I have raised the question about soldering to Brass, which contains
lead, with a lead free alloy and ending up with a non compliant alloy
i.e. the lead in the brass goes into solution in the solder alloy.

However on an assembly that doesn't need to be compliant we use
Multicore 96SCLF300AGS85 and it wets a dream. I admit the brass was
machined about a week before we do our bit.

Subject: [TN] PB-Free Solder and Brass

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.



TIA
