Susan,

1. I would think this situation might fall under para 4.2.2 "Referee Tests"
in 6012.

...back to "microsection defects that are isolated or random in nature"

2. ERGO, It appears this person is saying the registration defect is in an
"isolated" area of the board.

3. If this para applies, he would need two additional sets of sections
without defects.


Mike

Even tho we are not finished with the first topic of Zone B I would like to
start another conversation.

I have a note from a board fabricator that was sent to his customer that
says

"Group A microsection submissions for this part number do nt meet your
internal annular ring requirements.  This notification relates to parts from
panels 1 and 2.  In an effort to minimize cost and meet customer delivery
requirements, it is our policy to alsvage partial panels on lots with
internal annular ring failures.  In this case we used additional
microsections or rgistration coupons to show that the internal annular ring
on some of the parts on the panels mentioned ar compliant.  The
non-compliant parts next to the failed microsection coupons have been
scrapped.  We hope that yu see the benefit of this practice and that it has
not created you any inconvenience."

This note was submitted because some of the coupons I received for Group A
testing for this lot, as an independent check, were rejected since they did
not meet specification or drawing requirements for annular ring.

The board fabricator asked "well where does it say that the whole panel
fails, if the coupons fail?"

Of course at this moment I have not been able to find those exact words.

SO - do we need to add those explicit words with the instructions that ONLY
THE BUYER OF THE BOARDS CAN WAIVE NON-COMPLIANT CONDITIONS ON A PANEL OF
BOARDS.

Thanks again for all the help
