With laser-assisted cleaning technology is the mechanism to solve this problem: First, by using laser light to be clean material, particulate or surface absorption of laser energy, the force generated due to thermal diffusion impact will leave the surface of the particles. Second, the laser energy by particles around and following cleaning agent (water) absorption, leading to cleaner heating and explosively rapid vaporization of the particles away from the surface. The third is to be cleaned material to absorb the laser energy, this energy is then heated cleaning agent, leading to explosive vaporization and remove particles. Experiments show that with laser-assisted surface cleaning methods get rid of the semiconductor particles is effective for highly integrated semiconductor devices to improve the yield shows a bright future. The workshop prepares the new working table ofGreen laser pointer.High-power microscope with a beam of laser focus to 1-2μ, the particles in the vicinity of the laser waist was captured by force, the captured particles can be fixed or moving up to the desired location. This laser tweezers technology has been used in biomedical research, it is being studied for microelectronics manufacturing. In the laser welding process, when the laser beam hit the metal material, the heat transfer by thermal conduction to the surface and deeper below the surface. The role of the laser heat source, the material melting, evaporation, and the thickness direction of the workpiece through the formation of long and narrow hollow, with the laser welding carried out holes along the seams between two moving parts, thus the formation of the weld. Salient features of laser welding is a big melting, bead, small heat-affected zone, and high power density. The workshop has changed the working time table ofgreen laster pointer. Laser welding represents a small area in between the heating and cooling fine balance. The purpose of laser welding is produced by radiation absorption liquid bath, and make it grow to the ideal size, and then move along the solid interface, eliminating the welded components of the initial gap between the formation of high-quality welds. Pool is too large, too small, or the evaporation of a serious, will lead to weld failure. In addition, the final weld quality may also change due to deterioration of other factors, such as the alloy composition of the evaporation, the thermal gradient is too large (leading to thermal cracking), and the weld pool size and geometry of the instability (leading to holes and empty points) and so on. Balance between heat input and output of the laser stability of Wei Hu and energy absorption of the uniformity of the workpiece within the transmission. Laser to the workpiece transfer means? Is often the focal point of the laser interference generated by the steam, under certain conditions, this steam can be turned into plasma, thus leaving the sputtering due to the absorption and laser intensity decreased. Thegreen laster pointercompany has the strict rules and regulations. Exist in the weld pool, the fusion zone and the surrounding matrix material between the stability of the interface geometry, heat transfer is to determine the internal stability of the workpiece major factor in moving the workpiece during welding or laser beam is moving, the solid-liquid interface? Often been interference, therefore, the cooling rate in the weld pool must introduce additional geometry factor. Since there are so many potential limiting factor will be hard to imagine high-quality laser welding seam. However, regardless of the excitation laser welding process and cooling balance of the number of constraints exist, a lot of heat and mechanical time constants can still work together to meet the requirements of laser welding, and reduce to a certain degree of volatility, and thus establish a stable welding conditions. Thegreen laster pointercompany asks the staff members to wear the labor protection appliance during the manufacture process. Laser Welding Research Analysis of the primary goal is to affect the stability and reproducibility of laser welding parameters, and seek to control these parameters. This is the first departure from the laser source itself, because the volatility of output power and mode converted into the weld pool thermal fluctuations, leading to the stability of the laser welding process does not produce. Laser-material interaction with the highly nonlinear characteristics of the process means that some of the fluctuations in the amplitude of the rapid increase, which also provides the possibility of controlling the laser welding process and the reality, namely the use of a variety of sensors to detect sound, light, fluctuations in signal power, and effective treatment, thereby selectively changing the laser output. The shoe for the worker in thegreen laster pointerworkshop is specially made.
