Help...

A customer has brought a problem to our attention. The yare experiencing
'air bubbles' in through holes after wave soldering.

The copper plating in the hole is averaging 1.25 mils, we have not seen
any compromised hole walls, only bubbles, they even extend up and out of
the hole next to the component leads.

I have uploaded pictures on our website, any assistance would be
appreciated.

These boards were fabricated here in Texas 13 months ago, the customer
did not bake the boards prior to processing. Thanks
