Paul,

we run SN96 here A LOT and it is, by design, 96.5/3.5. The SAC alloy is the
same, but with .5 percent copper taking away from the silver side.

Subject: [TN] Pb-Free


Does anyone think that 3.5% Pb in a SN96AG4 (aka Pb-free) is abnormal? I
think it is, but I have doubters here. This was measured by EDX.

Does anyone have any evidence what this does to reliability?
Specifically mechanical cycling.
