The principle of the laser cutting machine is to use a very thin laser beam and appropriate energy density to irradiate the thick and thin film resistors. The resistance body of the chip resistor is gasified to change the cross-sectional area of the resistance to realize the cutting. With the process of laser cutting, the change of resistance value of chip resistor is measured and monitored by measuring system in real time. When the actual resistance value of chip resistance reaches the target value, the laser beam is turned off, that is to say, the laser resistance repair process is realized. Laser trimming resistor has the characteristics of high precision, high speed, high reliability and low cost.
PCB laser resistance repair machine
Laser resistor adjusting machine is a key equipment for engraving thin film or thick film resistor and realizing precise adjustment of resistance value. In the production of portable electronic products, the use of precision laser resistor modulator as processing equipment has great development potential. Due to the high technology content of laser resistor trimming machine, it is necessary to master the semiconductor end pump laser technology, laser focusing and image monitoring technology, coaxial numerical control software and image vision automatic identification and positioning technology, ate (automatic test tooling) and other technologies.
