AI Technical Summary

Technical Problem

Existing memory module etching equipment cannot dynamically adjust the etching line speed, resulting in excessive line width deviations due to copper thickness fluctuations and material differences. This affects the electrical performance and signal transmission quality of the memory module. At the same time, the testing equipment is complex to maintain, increasing production costs and downtime.

Method used

By combining an eddy current sensor and a high-speed CMOS camera with a microcomputer, the speed of the conveyor motor is dynamically adjusted through a PID control algorithm to achieve precise regulation of the etching line speed. The detector is designed to be detachable for easy maintenance and installation.

Benefits of technology

It enables dynamic and precise adjustment of etching line speed, avoids line width deviation, improves production efficiency and product quality, reduces maintenance costs and manpower input, and extends equipment life.
