RE>>OSP Coating 11/6/96
Lothar,
Our Workmanship Standards are essentially IPC 610, Class 2, Rev B, but we've added a waiver to address the lack of a "sufficient" top-side through hole fillet. Rev B is a bit more generous than was Rev A in this respect, but the waiver is still needed.
Regards,
Greg B.

My question is: When using OSPs with mixed technology, how is the issue
of hole fill and top-side wetting of the annular rings addressed?
