I have a customer that is required to use a Lead Free solder to attach some brass components (battery contacts) to a PCB. What he is experiencing is the brass will not tin using this solder. Anyone have any suggestions: Solder required for use: Cookson Electronics - Alpha Cleanline 7000 Alloy 96.5Sn 3.0Ag 0.5Cu Flux: P2 The contact material is: 360Brass His customer is in a rush for these components, and is demanding the Pb-free be used. BTW - the good old fashion No-clean and Rosin (both of these have lead in them) work great.
