Hi Jens In your region , contact Carl from Alpha Metals ; AM in conjunction with launching of their new silver Alpha Level ( we tested it up to 100000 switching cycles against carbon pads fine ) did a huge comparing study of ALL copper finishes on solderability , vetability , etc. If you express interest in the silver AlphaLevel , you'll get it as part of presentation . Otherwise, you can not expect much from tin to gold shift on solderability, especially with more passes .
