Surface appearance after chemical polishing
SEM images of copper material surface after chemical polishing (40℃/15 s) using Melpolish CU-1220 and a reference (conventional process). Surface roughness is drastically improved by applying Melpolish CU-1220.
Results of salt spray test
Surface after salt spray test (35℃/96 h/, no sealing) of copper pieces plated with nickel/gold after chemical polishing. No corrosion was observed on the piece applying Melpolish CU-1220.
Influence of temperature on etching rate
Ething rate increases with proportinal to bath temperatures: 1µm/min for 5℃.
