Laser trimming machine for Automobile industry Temperature/Positioning Sensor

Product Specification

Laser trimming machine for Automobile industry Temperature/Positioning Sensor

Distription

The laser resistance trimming machine 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:

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.

Equipment model and performance

LT7 series laser resistance trimming machine is a high-end configuration type laser resistance trimming machine

LT7 series products adopt advanced special laser for laser resistance trimming.

High precision of resistance adjustment

Fast resistance adjustment

Strong function

High reliability and stability

The laser electro-optical conversion efficiency reaches 25%, and the average daily power consumption is less than 10 degrees, which is 1/10 of the traditional flash lamp pumped solid-state laser. Long-term use can save users a lot of energy expenditure, reduce carbon emissions, long service life, high performance Stable and maintenance-free, reducing downtime.
