Description
Data Sheet

Laser trimming equipment adopts highly focused micro laser beams with matched energy density to irradiate thick-film and thin-film resistor materials. The resistive body of chip resistors is gasified locally to adjust the effective cross-sectional area, so as to achieve precise resistance trimming. During the whole laser processing cycle, the integrated measurement system conducts real-time sampling and dynamic monitoring on chip resistance parameters. Once the measured resistance reaches the rated target value, the laser output will be cut off instantly to complete the automatic resistance calibration process. Laser resistor trimming technology features superior accuracy, high processing efficiency, long-term operational stability and cost-effective production performance.

PCB laser resistance repair machine

As core precision processing equipment, the laser resistance trimmer is dedicated to thin-film and thick-film resistor carving and accurate resistance parameter calibration. It possesses remarkable application potential in the mass production and manufacturing of portable electronic devices.

This high-end processing equipment involves sophisticated core technologies, including semiconductor end-pumped laser solution, laser focusing control, real-time image monitoring, coaxial numerical control software, visual automatic recognition and positioning, as well as automatic test tooling (ATE) and other key integrated technologies, leading to high overall technical barriers.
