Etched mesh It belongs to precision etching, and the feedback from customers during the etching process shows a large deviation of tolerance, resulting in small or large, so what is the cause? It mainly includes the following aspects.

1、Precision of film and drawings: low precision of film and drawings will make the etching net small or large；

2、Etching time: etching time is too short, may lead to small etched mesh, need to adjust the etching time in time；

3、Etchant concentration: the concentration of etchant varies from reaction to reaction, such as the higher the concentration of etchant, the faster the reaction speed, Etched mesh will be larger, and vice versa. If the concentration is too high and exceeds a certain value, the etching speed will be slowed down instead.;

4、Exposure accuracy: If the exposure is not accurate, the mesh will become larger or smaller with the size of the exposure。

Etched meshSmaller, mainly because of the etching process process precision is not enough. Zhuolida electronic factory professional 23 years etching process, can be processed to 0.02mm thick metal materials, etching processing accuracy up to + / - 0.0075mm precision, can achieve batch production processing, and the processing of stable quality, clear batch, strict quality control system.
