CuP-200 is a cost effective surface prep formulation providing controlled copper surface for better solder mask, Dry film and resist bonding.

CuP-200 is a novel cost effective alkaline aqueous surface preparation formulation used for multiple applications. CuP-200 provides superior substrate cleaning with controlled copper roughness. CuP-200 is the second in the series of copper surface preparation family of products.

CuP-200 is capable of providing:

- Controlled copper etch and surface roughness

- Organic and inorganic contamination removal from various surfaces

- Improved adhesion of solder mask, dry film and resist bonding with copper
