Introduction

The laser 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

The laser trimming machine 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.

• lPowerful database function, the entire production process is recorded and traceable.
• lThe warning function of unqualified products can effectively prevent unqualified products from flowing into the next process.
• lThe positioning coordinates are obtained in real time through the image, which is easy to operate and improves the positioning accuracy of the product.

High reliability and stability

• The core components are imported to ensure the quality
• lUsing special granite pedestal: It can effectively reduce the inertial vibration caused by the start, stop and acceleration of the workbench; at the same time, it can maintain the stability of the temperature of the machine.

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

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.
