... is the chemical silver refinement uncomplicated and reliable, but once the manufacturing parameters have been set they can be dependably utilised for further processing | MULTILAYER CIRCUITS SHOP | and continued use. Due to the thin surface layer – a thickness of 0.15 – 0.3 mµ is recommended – the surface of the pad | MULTILAYER CIRCUITS SHOP | is smoother and therefore there are, even in fine pitch areas, no restrictions when assembling. The silver functions merely as a protection against oxidation, and | MULTILAYER CIRCUITS SHOP | the actual solder point is between the copper and chemical tin, therefore the solder point is absolutely stable.
