Detailed introduction
The LTR series laser trimming machines are prestigious products of Changchun Guanghua Microelectronics Equipment Engineering Center Co., Ltd., with an 18-year history. Laser trimming machines are advanced, modern equipment for adjusting the resistance values of chip resistors. They employ a non-contact laser processing technology, boasting high production speeds (800,000 units/hour) and high trimming accuracy (1%, 0.1%), and are widely used in the microelectronics industry. This product is a modern, high-precision industrial device integrating optics, mechanics, electronics, and computing. It covers a resistance adjustment range of 5mΩ~200MΩ and features 26 types of lithographic knife shapes, including L-cut, II-cut, Z-cut, and S-cut. It is mainly used in the production of chip resistors of various sizes and specifications (01005, 0201, 0402, 0603, 0805, 1206, etc.), including thick-film, thin-film, metal-film, and functional circuit resistors. Guanghua Company holds complete independent intellectual property rights and can customize machine models according to customer requirements.
