Copper base PCB Etching quality and problems existing in the early stage

The basic requirement for PCB etching quality is to be able to completely remove all copper layers except under the corrosion resistant layer, and that is all. Strictly speaking, if we want to define accurately, the etching quality must include the uniformity of line width and the degree of lateral etching.Due to the inherent characteristics of the corrosion solution at present, etching not only downward but also on the left and right sides of the direction, so side corrosion is almost inevitable.


Lateral etching is often discussed in etching parameters. It is defined as the ratio of lateral etching width to etching depth, which is called etching factor.In the printed circuit PCB industry, it varies widely from 1:1 to 1:5. Obviously, small side etching degree or low etching factor is the most satisfactory.


The structure of the etching equipment and the etching solution with different components will affect the etching factor or lateral etching degree, or, to put it optimistically, it can be controlled.Some additives can reduce the lateral corrosion.The chemical composition of these additives is generally a trade secret, and their creators do not disclose it to the outside world.
