Automobile sensor film laser trimming microfiber towel
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
High reliability and stability
Low operating and maintenance costs
High efficiency, low energy consumption and cost saving
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.
Laser trimmer solution
The principle of laser resistance trimming is to use a very fine laser beam to hit the thick and thin film resistors, and realize the cutting of thick and thin film circuits by vaporizing the resistor body. The laser beam cuts the thick and thin film resistors according to the program predetermined by the computer, and changes the resistance value of the resistors by changing the geometric shapes of the thick and thin film resistors. As the laser cutting process progresses, the real-time measurement circuit monitors the changes in the resistance values of the thick and thin film resistors in real time, and the resistance values of the thick and thin film resistors are constantly approaching the target resistance value. That is, the laser resistance trimming process is realized.
When the thick film resistor is used in the electronic module, the function modification of the electronic module can be realized by adjusting the resistance change so that the output signal of the electronic module also changes.
Laser resistance trimming changes the conductive cross-sectional area and conductive length of the resistor body, and can trim the resistor body below the target resistance value to the required accuracy range.
