Melplate CL-1000S2
Melplate CL-1000S2 is an acid cleaner as the pretreatment for elecrolytic copper plating.
◆Features
1. The working solution shows low contact angle to copper surface and excellent permeability to small sized holeTHs or BVHs.
2. Excellent cleaning performance.
3. Effective to suppress pits and nodules on copper sulfate plating.
4. Easy bath control based on analysis of bath components.

Contact angle and surface tension
Melplate CL-1000S2 shows lower contact angle to copper surface and surface tension compared with conventional acid cleaner. The working solution spreads quickly over copper surface.
Cross sections of BVH and high aspect ratio through hole after electrolytic copper plating.
Excellent wettability of Melplate CL-1000S2 is efefctive to wet the inside of BVHs and high aspect ratio through holes, leading to he supression of air voids. This contributes to form reliable electrolytic copper deposit.
