1.1.3. DZA25P, AN515

The microetching agent is composed of DZA25P and DZA200, which is used for the microetching treatment of copper surface in the production of printed circuit board. It can uniformly reduce the thickness of copper layer and clean the rough copper surface. The liquid medicine is suitable for pre-dry film or pre-OSP microetching process.

Its main features are:

1) The etching rate is stable, the solution is clear and easy to maintain, and contains no organic solvent, which meets the environmental protection requirements;

2) Suitable for selective gold (silver) -OSP plate microerosion pretreatment, can avoid the copper plate erosion and wire breaking defects caused by the Givenini effect;

3) The copper surface has low roughness after microetching, which can improve the solderability of OSP plate and avoid the color phenomenon of OSP film surface.
