Principle of Laser Soldering Paste

Laser soldering is a laser welding technology in which a laser is used as a heat source to melt solder paste. The main feature of laser soldering is the use of high energy of astronomy laser pointer to achieve rapid heating of local or tiny areas to complete the soldering process. Laser soldering is compared with conventional SMT soldering. Has an irreplaceable advantage.

Traditional SMT technology, that is, surface mount technology, mainly uses wave soldering and reflow soldering technology. There are some fundamental problems, such as lead wires of components and pads on printed circuit boards, which will diffuse Cu, Fe, and molten tin. Various metal impurities such as Zn; molten tin is likely to generate oxides at high speed in the air. At the same time, in the traditional reflow soldering, the electronic components themselves are heated to the soldering temperature at a large heating speed, causing thermal shock to the components, and some thin package components, especially heat sensitive components, are destroyed.

At the same time, due to the overall heating method, PCB boards and electronic components have to undergo the process of heating, heat preservation and cooling, and their thermal expansion coefficients are different. The alternating heat and cold are easy to generate internal stress inside the components, and the internal stress exists. The fatigue strength of the solder joint is reduced, and the reliability of the electronic component is damaged. In addition, the excessive heating time of the overall heating method is liable to cause coarse metal grain of the weld metal and excessive growth of the intermetallic compound, thereby reducing the fatigue life of the solder joint. 532nm laser pointer soldering is a reflow soldering of local heating, which can well avoid the above problems.

Advantages of laser welding: Laser welding can achieve high quality joint strength and large aspect ratio, and the welding speed is faster. Since laser welding does not require a vacuum environment, remote control and automated production can be achieved through lenses and optical fibers. The laser has a large power density, has a good welding effect on difficult-to-weld materials such as titanium, quartz, etc., and can weld different performance materials. Micro soldering is possible. The laser beam is focused to obtain a small spot, and can be accurately positioned, and can be applied to the mass welding of micro- and small-sized workpieces produced by large quantities.

The military laser pointer beam can be focused to a small spot diameter, and the laser energy is confined within a small spot range, which can achieve strict local heating of the soldering part, and the thermal shock effect on electronic components, especially heat sensitive components, can be completely avoided. . The laser has a high energy density, a high heating and cooling rate, a fine metal structure at the solder joint, and an effective control of excessive growth of intermetallic compounds.

The input energy of the welded part can be precisely controlled, which is very important for ensuring the quality stability of the surface assembled welded wire joint. Since the laser welding can only heat the welded portion, the substrate between the leads is not heated or the temperature rise is much lower than the welded portion, which hinders the transition of the solder paste between the leads. Therefore, the occurrence of bridging defects can be effectively prevented.

The laser solder paste soldering process is divided into two steps: first, the green laser pointer solder paste needs to be heated, and the solder joints are also preheated. The laser solder paste used for soldering is then completely melted, and the solder paste completely wets the pads, eventually forming a solder. Due to the use of laser generators and optical focusing components for soldering, high energy density, high heat transfer efficiency, non-contact soldering, if the solder uses a common SMT solder paste, it will produce tin, splash, solder balls, wettability, etc. .

Principle of Laser Displacement Sensor

Laser displacement sensors measure precise geometric measurements such as displacement, thickness, vibration, distance, and diameter. Lasers have excellent linearity and military laser pointer displacement sensors have higher accuracy than our known ultrasonic sensors. However, the laser generating device is relatively complicated and bulky, and therefore the application range of the laser displacement sensor is demanding. According to the measurement principle, the laser displacement sensor is divided into laser triangulation method and laser echo analysis method. Laser triangulation method is generally suitable for high-precision and short-distance measurement, while laser echo analysis method is used for long-distance measurement. Principle of laser triangulation and principle of laser echo analysis.

The laser displacement sensor uses the principle of echo analysis to measure the distance to achieve a certain degree of accuracy. The inside of the sensor is composed of a processor unit, an echo processing unit, a laser transmitter, a laser receiver and the like. The waterproof laser pointer displacement sensor emits one million laser pulses per second through the laser emitter to the detector and returns to the receiver. The processor calculates the distance required by the laser pulse to meet the time required to reach the detector and return to the receiver. The output value is the average output of thousands of measurements. This is the so-called pulse time method. The laser echo analysis method is suitable for long-distance detection, but the measurement accuracy is lower than the laser triangulation method, and the farthest detection distance can reach 250m.

Semiconductor laser diode (LD) is a kind of laser used in optical communication system to build optical communication system. It can be used directly as a light source for optical communication, or as a pump source for lasers and amplifiers. Important position. It has the characteristics of semiconductor devices: small size, simple structure, high efficiency, and direct modulation, but the output power, monochromaticity and directionality are not as good as other lasers. Laser diodes have a wide range of functions and are often used as indicator light to point to the target, as a bright light to set off the atmosphere, as a surgical light for surgery, for measuring distance, for illumination, and for refrigeration. When the 532nm laser pointer diode is working, the heat consumption accounts for more than 50% of the total power consumption, and the negative impact of heat consumption is relatively large. Reduce output power and shorten service life. It can even cause the temperature of the LD to be unstable to change its output wavelength. To solve these problems, we need to do research on heat dissipation.

For low power laser diodes, passive cooling can meet the demand. The larger ones can use air cooling. However, these two methods of heat dissipation have many limitations. Water-cooling heat dissipation is a high-performance heat dissipation method using laser diode cooling. The copper heat-absorbing box is placed in the hot core part, and the water pump and the heat sink are connected through the pipeline to transfer heat to the external heat dissipation. This heat sink is primarily used as a horizontal laser diode stack in diode pump lasers or direct diode lasers for industrial, medical and research applications.

Laser displacement sensors are commonly used for measuring physical quantities such as length, distance, vibration, speed, and azimuth. They can also be used for flaw detection and monitoring of atmospheric pollutants. Position identification of small parts; monitoring of parts on the conveyor belt; detection of material overlap and coverage; control of robot position (tool center position); device status detection; device position detection (through small holes); liquid level monitoring; Thickness measurement; vibration analysis; collision test measurement; vehicle related test. Thickness measurement of foil and sheet: The 18650 laser pointer sensor measures the thickness of the foil (thin sheet). Detection of changes in thickness can help detect wrinkles, small holes or overlaps to avoid machine failure.

Cylinder measurement, simultaneous measurement: angle, length, inner and outer diameter eccentricity, conicality, concentricity and surface profile. Measurement of length: The component to be measured is placed on a conveyor belt at a specified position, and the laser sensor detects the component and measures it simultaneously with the triggered laser scanner, and finally obtains the length of the component. Uniformity inspection: put a few laser sensors in a row in the oblique direction of the workpiece motion to be measured, and directly output the metric value through a sensor. Alternatively, a software can be used to calculate the metric value and read the result according to the signal or data.

Inspection of electronic components: Two laser scanners are used to place the device under test between the two, and finally the data is read by the sensor to detect the accuracy and integrity of the component. Inspection of the filling level on the production line: The laser sensor is integrated into the production of the filling product, and when the filling product passes the sensor, it can be detected whether it is filled or not. The sensor uses an extended program of the astronomy laser pointer beam reflecting surface to accurately identify the filling of the filling product and the number of products.

Water-cooled heat dissipation has the characteristics of high heat dissipation efficiency, quietness, greenness and stability, and is very suitable for heat dissipation of electronic devices below 3000W. The cooling of semiconductor laser diodes is a very important part. The application of water cooling and heat dissipation has greatly improved the short board of heat dissipation, which has effectively promoted the good development of LD equipment.

Application of Laser Technology in Automobile Field

Since the early 1980s, the automotive industry has been one of the main drivers of the high-power laser industry. This industry has strict requirements on the quality and reliability of laser sources. Compared to traditional manufacturing techniques, laser technology can bring greater benefits in the areas of cutting, welding and marking. Because 18650 laser pointer technology is more flexible than traditional technology and easy to automate, it can meet the core requirements of the entire industry. In the beginning, the laser was only used for simple cylindrical part welding, such as the automatic transmission components of a vehicle. Nowadays, lasers have been widely used in the process of processing the entire vehicle structure. Roof welding, door welding, three-dimensional cutting of hydroformed parts, door spring annealing, instrument panel welding, marking, etc. are just a few examples of a large number of laser applications. With the development of lightweight vehicles, new materials, new structures and new processes are constantly emerging, and the safety performance of automobiles is continuously improved.

Laser ranging technology is the first laser technology to be practically applied in the military. In the late 1960s, laser rangefinders began to be equipped with troops, which were widely used for reconnaissance surveys and weapon fire control systems because of their ability to quickly and accurately measure target distances. Laser guided weapons have high precision, simple structure, and are not susceptible to electromagnetic interference, and they play an important role in precision guided weapons. The astronomy laser pointer communication has large capacity, good confidentiality and strong anti-electromagnetic interference capability. Optical fiber communication has become the development focus of communication systems. Airborne, spaceborne laser communication systems and laser communication systems for submarines are also under development.

A tactical laser weapon made of a high-power laser can blind the human eye and disable the photodetector. stage. Anti-satellite and anti-continental ballistics using high-energy laser beams may destroy military targets such as aircraft, missiles, and satellites. The application of strategic laser weapons that are close to practical missiles is still in the exploratory stage. Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can achieve better cutting quality and extremely high cutting speed and efficiency, while reducing tool wear. The use of laser welding materials can avoid deformation, increase the type of welding materials, eliminate environmental factors, high quality and efficiency.

The use of military laser pointer technology welding, its advantages are extremely high welding speed, stable welding quality, high welding precision, small thermal deformation of materials, and easy to integrate into the automation operating system, which is widely used in modern industrial production, with excellent reputation. Advanced welding methods. Laser welding has been widely used in automobiles, such as welding of automobile bodies, pipe welding, welding of automobile batteries, and plastic welding of instrument panels. Lasers have unique advantages in terms of welding strength and welding precision and speed.

Laser cutting is also one of the most frequently used laser applications. Fiber lasers and CO2 lasers can be combined with standardized 2D and 3D cutting systems to cut low carbon steel, stainless steel, aluminum and other metals. When processing different parts of a car, car manufacturers take advantage of the advantages of laser cutting, such as high cutting edge quality, low heat input, and fast processing speed. Automotive parts and materials, including a variety of metals, such as airbag fabrics and composite materials used in automotive interiors, are cut using a laser. As a flexible processing tool, the laser can be easily integrated into robots and other automation devices and provides solutions for the cutting of various automation components and materials.

In addition to traditional processes such as laser cutting and laser welding, lasers can also be used in a variety of surface treatment applications such as 532nm laser pointer hardening, laser de-layering, surface activation, and laser surfacing. In the laser surfacing process, the most well-known is laser cladding. The basic materials such as metal wire or powder can be melted by laser radiation to achieve metallurgical bonding. The dilution rate of the metal of the parent component is less than 5%. . The automotive processing industry usually uses powder for laser surfacing, which can be used as a protective film for workpieces to prevent wear and corrosion, as well as high temperature and corrosion resistance (liquid). In the automotive industry, the minimum distortion rate and high flexibility of the workpiece are two important criteria. Thermal microcracking and porosity are also avoided due to reduced heat input and the use of additive materials.

The Advantages of Fiber Laser Cutting Machine

Under the unfavorable market environment of low price competition, a large number of domestic manufacturers and brands do not stand out, the relative lack of technological innovation, dependence on advanced foreign technologies and lack of core competitiveness. At the same time, rising labor costs, coupled with rising raw materials, have also increased the cost pressures of many enterprises. It can be predicted from the above phenomenon, intensive mode of development will be a lot of blue laser pointer pen cutting machine business in the future direction.

Laser cutting machine companies need to come out from the price competition, turn to practice internal strength. Focus on product structure optimization, product quality improvement, core technology mastery and innovation, as well as the expansion of corporate brand influence. Of course, this series of changes require companies to invest more capital, this, laser cutting machine companies also need according to their own circumstances, the future of the input-output ratio to make a scientific estimate, so that selective investment, the gradual transition.

The working principle of the fiber laser cutting machine is that the laser is used to generate the laser, the laser is then transmitted to the cutting head through the optical path, and then the focus is achieved. The unit energy of the focused unit is high, and the high energy density focuses on the metal to be cut Surface, resulting in very high temperatures, the moment the metal melts, and use the auxiliary gas blowing off the slag, the formation of cutting seam, to cut the purpose. Fiber high powered laser pointer cutting machine with high precision, cutting fast, not limited to the cutting pattern restrictions, automatic layout to save material, cutting smooth, low processing costs, will gradually improve or replace the traditional metal cutting process equipment. Fiber, YAG and CO2 laser cutting machine principle is similar. What they are different is the size of the laser is not the same, the key configuration is different. It is precisely because of these differences determine the laser cutting machine processing capacity and value.

With the development of industrialization, the demand for thin plate in the future market is increasing, and the demand for fiber laser cutting machine will be more and more big in all walks of life. At the same time, the market demand for this kind of machinery will continue to improve. Any product is compared to have the effect, the effect of fiber laser cutting machine in many people seem to be much better than ordinary mechanical cutting machine, this comparison is not only the choice of human progress, but also social progress for the promotion of modern industry.

Advantages of fiber laser cutting machine: high cutting accuracy, laser cutting machine positioning accuracy 0.05mm, repeat positioning accuracy 0.03mm. The cutting seam of laser cutting machine is narrow, and the green laser light beam is focused into small light spots, which makes the focus reach a very high power density. The material is heated to the degree of gasification quickly and evaporated to form holes. With the relative linear movement between the beam and the material, a slit with narrow width is formed continuously, and the kerf width is generally 0.10-0.20mm. The cutting surface of the laser cutting machine is smooth, the cutting surface has no burr, and the roughness of the incision surface is generally controlled within Ra6.5. Laser cutting machine speed, cutting speed of 10m/min, the maximum positioning speed of 30m/min, much faster than wire cutting.

Good cutting quality of laser cutting machine, non-contact cutting, cutting edge heating effect is very small, basically no thermal deformation of workpiece, completely avoid the formation of material punching when cutting edge collapse, generally do not need two processing. Without damaging the workpiece, the laser cutting head will not contact with the material surface, so as to ensure that the workpiece is not scratched. Not affected by the shape of the workpiece, laser processing flexibility is good, can be processed arbitrary graphics, cutting pipe and other special-shaped materials. Laser cutting machine can cut a variety of materials, such as plastics, wood, PVC leather, textiles, plexiglass and so on. The mold investment is saved, the laser 303 processing needs no mould, no die consumption, no need to repair the mould, save the replacement mould time, thus saving the processing cost and reducing the production cost, especially suitable for the processing of large products.

Laser Hardening to Achieve New Quality

Safe manufacturing of steel with 14% to 22% chromium and more than 1% carbon steel thin-wall cutting tool or a new application. Here, since the component mass is too low, and the component has a martensitic starting temperature is near room temperature and the end of the temperature is about -10 ℃ material properties, and above the temperature point can reach the target hardness, so the use of traditional laser The hardening process does not guarantee the quality of self-quenching.

Common blue laser pointer processing on the market is reflected in the choice of a good temperature to the parts of the heating, and a certain amount of laser feed to the heat into the steel to achieve the hardening of the final hardness depends on the characteristics of parts and their quality.

High-quality laser hardening treatment based on the variety of steel, independent analysis of alloy composition and determine the state of the quenched and tempered. According to the user's hardening task requirements, to develop a wide range of processing processes. Also included in the scope of work is the sample parts or parts of the tempering and deep cooling. The quality assurance after hardening treatment involves authorizing a partner to use the laboratory quality identification and other technical means to determine the processing results, and through the metallographic method to verify the results.

In the critical context, together with an external material inspection laboratory for the work of the task and the final quality verification and other aspects of the advanced research. At the same time, this cooperation also plays a role in the development of the products required by the user, such as the reliability test of the stability of the tool and the inspection of the cutting capacity in the specific workplace. Only advanced research to make the smooth end of the work, can begin to accept the user parts of the green laser pointer hardening of the commission. Common laser quenching process on the market and a certain amount of laser feed to adjust the tool to achieve the same quality level.

The use of robots to implement laser hardening work, so the application of laser hardening is very flexible. It is only a small amount of preparation work on the equipment components or components to start the laser hardening treatment, and all other laser applications, this hardening method is equally efficient. This technology in the application of the performance of fast, save money, does not depend on any form, can be installed strong, high efficiency and good security. Once the task negotiated, within 24 ~ 36h to complete a single piece of processing. In the commissioning of hardening processing services, the standard range of daily processing tasks is from the small changes in the size of the precision components, until the large pump chassis, rope pulley and hundreds of kilograms of large die for processing. In order to improve component rigidity and reduce component thickness to save material during high quality hardening processes, functional levels such as cutting and quality-free stabilizers are applied. The structural stabilizer is a strong laser pointer trajectory that produces a high rigidity and a low vibration tendency within the component, which can be used in component design concepts and FEM analysis.

A good example of a laser hardening process is the ability to extend the life of the tool on the slaughtering device, which is also the case for the meat cutter. The cutting speed of the tool with the sausage material can reach 700km / h at the time of operation. This kind of thin plate tool will suffer the maximum load such as tapping or vibration during its use. The main load is from the vibration, which is often caused by the fatigue of the material. Cut the tool. Laser hardening can be achieved by laser hardening marks so that the soft tool body becomes stable and hard, thus reducing the probability of tool breakage. The test results show that the laser quenched cutter in the amount of vibration and vibration duration than the overall quenching or quenching of the tool is much stronger.

However, the thin plate tool can not ensure that the quenching process required self-cooling, in this case the need to meet the requirements of the tool quenching method, which developed along the red laser pointer traces of the immediate after the cooling. Thereby successfully achieving the goal of orienting and rapidly cooling the thin-walled material below the starting point of the martensite to ensure a good hardening treatment result. In this way, it is possible to perform a hardening treatment with a sheet with a wall thickness of only 1.5 mm.

Laser Application Technology

Laser refers to the product of stimulated emission light amplification, it has a monochrome, collimation, coherence and high energy density and other characteristics. It is because of the superior characteristics of laser, people will be widely used in human life in all aspects, such as printing, welding, cutting, communication, storage, etc., can be said that the blue laser for human production and life brought a qualitative leap. However, at the same time, the laser has also brought a lot of security to the human problem.

Metal marking machine is mainly used in laser marking processing, but the laser marking a wide range of metal materials can be marked processing is usually selected fiber laser matching marking equipment, such as carbon dioxide laser marking device is Can not be processed on the metal marking, the reason why there will be such a reason, with its own wavelength and its own characteristics of the decision. Fiber lasers due to the use of optical fiber transmission, and industrial machinery control flexible integration of higher, free from space or location factors, more able to achieve semi-automatic, automated, intelligent direction, the expansion of space is greater, while fiber green laser pointer almost No maintenance, power stability, good beam quality, long-term application cost-effective, easy to use, no need to replace any other accessories.

Static laser energy spectrum is a stable spatial distribution. Mainly applicable to micron-scale particles of the test, after the improvement can also be extended to tens of nanometers measurement. The dynamic laser analyzes the size of the nanoparticles by detecting the dynamic light scattering signals of one or two scattering angles according to the speed of the grain Brownian motion, and the energy spectrum changes with time. The dynamic light scattering principle of the particle size analyzer is only applicable to nano-scale particles. Transparent settlement usually refers to the laser particle size analyzer refers to the principle of diffraction and scattering particle size analyzer, light through the settlement instrument, based on the principle of Stokes settlement law rather than high power laser diffraction / scattering principle, so this instrument can not be called Laser particle size analyzer.

With the rapid development of laser application technology, many of the traditional manufacturing industry, the introduction of laser technology for products for enterprises to bring technological innovation and new impetus, but many companies do not do laser product safety certification preparation, for laser Of the hazards, the level of laser safety, the evaluation criteria and the national market for laser safety requirements are relatively unfamiliar. Mainly in the following areas: R & D design, production and processing personnel do not have the experience of laser work; corporate norms did not establish a sound laser safety requirements; personnel and facilities of laser safety protection is not in place.

The application of the laser in the client often requires the combination of laser shield, fiber, robot, exhaust and other ancillary equipment to form a complex red laser pointer processing production system. The systematic safety assessment of these laser processing systems is often overlooked by the enterprise. Compared to the safety requirements of a single laser device, the safety assessment of the laser processing system is much more complex: not only requires the laser light source to be designed to meet laser safety requirements, but also to require all parts of the system to work together to prevent all possible hazards ; Not only to consider the laser beam-related hazards, but also to consider electrical hazards, mechanical hazards, chemical hazards, ionizing radiation hazards, toxic and hazardous substances hazards.

The person in charge of laser safety refers to the personnel designated by the enterprise who have sufficient knowledge of laser safety and can assess and control the laser hazard for the enterprise. The person in charge of laser safety needs to be involved in all activities that may cause laser hazards, and to manage the laser pen safety issues within the enterprise. Enterprises need to introduce the laser safety in the management system and organizational structure, giving the laser safety responsible person full power, the formation of internal focus on laser safety system.

Laser Cladding Surface Nanotechnology

Laser cladding, also known as laser cladding or laser cladding, laser irradiation and laser remelting, are directly treated with matrix material without the addition of other materials, but laser cladding is achieved by adding a clad material to the substrate surface and using high Energy density of the blue laser pointer beam, so that with the substrate surface layer of the method of melting together, in the formation of the base layer with its metallurgical combination of filler cladding.

Laser cladding surface nano-technology can be divided into three main aspects, the first aspect is the use of similar laser remelting surface nano-method, take appropriate measures directly in the laser cladding process to make the deposited layer of nanocrystalline structure. There are two types of this method, one is the melting material and the substrate composition is basically unchanged, the formation of laser cladding pool and the formation of cooling to the main physical process, this method is currently relatively rare literature. The other is in the laser cladding process between the melt and the substrate, or between the welding material and the deposition of chemical reaction between the formation of nano-particles or nano-size organization.

Laser shock peening (LSP) is a kind of high and new technology to improve the fatigue, wear resistance and corrosion resistance of metal materials by using plasma shock wave produced by most powerful laser beams. The impact of laser surface nanocrystallization technology as shown in Figure 6, when the short pulse (NS) high power density (GW/cm2) of the laser irradiation to the metal surface absorption layer, absorbing layer to absorb laser energy explosive vaporization, high pressure (GPa) plasma, the plasma is constrained layer constraint, produce high impact wave effect on the metal surface and to the internal communication, the formation of dislocation structure dense and stable on the surface of the material, plastic deformation by dislocation slip, and the shock wave at the grain boundary reflection and refraction, the shock wave in multi direction effect on grain, thus the complexity of the dislocation slip, agglomeration and annihilation after the formation of new grain boundary, sub grain formation and smaller nanocrystals.

Researchers at the University of Rochester in New York have developed an extraordinary new surface material by bombarding ordinary metals with femtosecond 300mw laser pointer pulses, which can effectively absorb light, water and self-purification. Through the super-laser pulse in the metal surface etching a large number of naked eye, such as pits, beads and fine lines and other "traces", these traces of the formation of dense distribution and uneven nano-microstructure. This nanostructure fundamentally changes the optical properties and wetting properties of the metal surface.

The application of surface treatment technology has a long history, but the surface engineering technology from concept to become a complete system of time subject to, but now only a few decades, laser surface nanocrystallization technology of laser technology and nanotechnology and surface engineering technology combined or can also be called laser nano surface engineering technology.

Although the use of a variety of laser surface treatment technology, such as laser irradiation, laser remelting, laser cladding and 100mw laser pointer shock, has a lot of research materials and achieved fruitful results, but specifically targeted for the use of these technologies, The research on surface nanocrystallization is still relatively small and not systematic, and the development of nano-patterning of laser surface is still in the early stage, so there is still a lot of research work in this field.
