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.
