CuP Products can be diluted for use in both mechanical and chemical micro-etching processes.

CuP Products have been successfully used in brush cleaning systems for smooth copper surface prep/cleaning in high volume productions after copper pumice scrub type processes, etc.

CuP Products are a cost effective surface prep formulation providing a controlled copper surface for better solder mask, dry film, and resist bonding.

 

CuP Products are a novel cost effective alkaline aqueous surface preparation formulation used for multiple applications. CuP Products provide superior substrate cleaning with controlled copper roughness.

 

CuP Products are capable of providing:

 

- Controlled smooth 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
