Laser trimming Machine for Automobile Sensor

Introduction:

The laser resistance trimming machine of Wuhan Questt ASIA Technology Co., Ltd. is specially developed and produced for the thick film circuit and thin film circuit industry. Source trimming (resistance adjustment) and active trimming (circuit function adjustment) are mainly used for high-precision trimming of thin-film, thick-film, hybrid integrated circuits and various electronic modules, involving the following industries:

1.Automotive Electronics

2.Sensors

3.Communication electronics

4.Military industry is in scientific research

5.Medical

6.Industrial Electronics

7.Aerospace

The laser resistance trimming machines produced by our company are independently developed from the core measurement control system, software system, etc., and have all independent intellectual property rights, which can provide customers with comprehensive laser resistance trimming application solutions.
