What are the issues that need attention when etching processing of optical inks？The problems that should be paid attention to in the process of using the photosensitive ink during etching are mainly the following points:1. Drying temperature and time: In order to achieve the effect of the coating, y

Improve the uniformity of the etch rate across the board surfaceThe etching uniformity of the upper and lower sides of the board and each part of the board is determined by the uniformity of the etchant flow on the board surface. During the etching process, the etching rates of the upper and lower p

The main problems that should be paid attention to in the process of using photosensitive ink before etching are as follows:1. Drying temperature and time: In order to achieve the effect of coating, a certain amount of solvent will be added to the photosensitive ink as dilution to adjust the viscosi

In the chemical etching process method, the parts or parts that have been coated with a graphic anti-corrosion layer are placed in the corrosive solution for corrosion, and the corrosion is continued until the metal thickness reaches the requirements or the graphic depth reaches the requirements. In
