<< What is the plating on the board? Could it be that the boards are now two
months older than when you started and you are beginning to get a shelf life
problem? Is this a new batch of boards? We need some more data on the board
construction, hole to lead ratio, solder mask type.

Hello Al,
These boards are consigned, but I'm assuming it's just regular ol'
tin/lead HAL, looks like it to me anyway. Datecode says 4098...just last
month, two-layer board, nothing special. LPI SMOBC, axial holes (where the
solder's falling out) are .035", and my Mitutoyo tells me that the leads are
.025" - .027".
While I send this off, I'm gonna go back to the stockroom and get me a
bare board and REALLY scope that puppy out, supposedly, we just got another
kit today and maybe I can see something on the fabs...
I appreciate you taking your time on this...thanks!
