Okuno Pharmaceutical Industry has established a final surface treatment process that forms a void-free and uniform plating film on the circuit surface.
Okuno Pharmaceutical Industry has established a final surface treatment process that forms a void-free and uniform plating film on circuit surfaces. The "ICP-COA process" is a low film thickness Ni-P/Au plating process that utilizes a reducing cobalt catalyst. This process consists of a reducing cobalt catalyst solution "ICP Accel COA" and an electroless Ni-P plating for cobalt catalysts "ICP Nicoron COA-GM." In conventional processes using palladium, the copper material corrodes during the catalyst application step, leading to the formation of voids between the copper material and the plating film, which has been a challenge. In this process, a uniform catalyst film can be formed through reduction deposition, enabling the reduction of the film thickness of electroless nickel plating (electroless nickel plating thickness: conventional process: 3.0µm, ICP-COA process: 0.5µm). Furthermore, since a void-free and well-covered film can be obtained, it is possible to reduce the film thickness of electroless Ni plating without compromising solder joint reliability.
