CuP-100

CuP-100  can be diluted for use in both mechanical and chemical micro-etching processes.

CuP-100 has been successfully used in brush cleaning systems for copper surface prep/cleaning in high volume productions after copper pumice scrub type processes, etc.

CuP-100 is a cost effective surface prep formulation providing controlled copper surface for better solder mask, dry film and resist bonding.


CuP-100 is a novel cost effective alkaline aqueous surface preparation formulation used for multiple applications. CuP-100 provides superior substrate cleaning with controlled copper roughness. CuP-100 is the first in a series of copper surface preparation family of products.


CuP-100 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
