Hello,

Starting a new branch here.

"All of the other issues pale in the face of fractured SJs due to
soldermask compression during cyclic operation."

Is this concern specifically for BGAs, or the same for any soldermask
defined pad, even including selectively waved through-hole (PbFree)?

Thanks,
-Chris
