Laser trimming is widely used in the electronics industry at present. Laser fine-tuning of resistors and capacitors makes it very small in thermal impact on the adjacent components when processing, and does not produce pollution. It is easy to be computer-controlled and has the advantages of fast speed, high efficiency and continuous Monitoring and other advantages, compared with conventional fine-tuning method, but also has high precision, good reproducibility and resistance does not change over time characteristics.
Laser trimming is widely used to fine tune the parameters of thick, thin film components and circuits, including resistors, capacitors, quartz resonators, parameter tuning of monolithic filters, hybrid integrated circuit amplifiers, voltage dividers, current stabilizers, digital simulations and simulations Digital converters, high frequency oscillators, operational amplifiers, quartz crystal devices (including oscillators, filters), and fine tuning of semiconductor integrated circuits, eliminating the limitations that affect the accuracy of multiple integrated circuits.
Timely insertion of gun procedures. It can prevent the welding splash from clogging the welding nozzle and the contact tip, ensuring the cleaning of the welding torch, improving the life of the nozzle, ensuring reliable arc starting and reducing welding spatter. Torch space transition requires a shorter trajectory, smooth, safe. Choose a reasonable welding sequence. To reduce the welding deformation, welding gun walking path length to develop the welding sequence. Optimize laser welding machine welding parameters. In order to obtain the best welding parameters, the production of test pieces for welding test and process evaluation. Reasonable position changer, welding gun attitude, torch relative connector position. After the workpiece is fixed on the positioner, if the weld is not the ideal position and angle, it is required to constantly adjust the positioner during programming, so that the welded welds will successively reach the horizontal position according to the welding sequence. At the same time, the need to constantly adjust the position of each axis of the robot, reasonable to determine the position of welding torch relative to the angle and the length of the wire protruding. After the position of the workpiece is determined, the position of the torch relative to the joint is difficult to observe by the eyes of the programmer.
Because the astronomy laser pointer beam can be precisely oriented, positioned within the minimum size area, and combined with a small thermal area of action in the specified form, precision thin-film elements can be fine-tuned because there is no intermediate (chemical) process in the process and can be performed in the atmosphere In the processing, so real-time test results, and laser processing process to achieve automation, with high precision, process is simple and efficient features.
Using traditional cleaning methods such as media ejection or chemical cleaning, real-time monitoring is often difficult. Blasting media and the accompanying dust can obscure parts and optical coated components, whereas chemical cleaning is essentially a corrosive process environment. It is irrelevant that these processes can also cause more damage to the substrate.
However, with laser cleaning, the machine vision can be integrated into the device and the part under cleaning can be checked with the appropriate filters. This makes it possible to inspect the components coaxially to determine if they are completely cleaned or if additional cleaning channels are required.
