(((nodding in agreement)))

It's always the ancillary costs associated with NCP that when tracked, and
reported upon, scream the loudest about any given quality issue... 

Most often the only number (dollar amount) tracked is material cost, and
maybe process cost, but what about all the bs or administrative cost (loss)
in dealing with the issue, or more precise, recovering from the issue...
This should be factored into the cost of nonconforming product as well...

Sure. Why not? They have that goal to cut costs.......

Do you keep track of quality issues for circuit board suppliers? Every
time a PWB fails receiving inspection (or anywhere else in the process)
an Non-conforming Material report should be written. Keep track of all
of the NCMs. Keep track of all of the hours spent in rework hours, your
time, purchasing time, supply line engineer's time, time spent
re-ordering replacement boards, re-receiving them, re-inspecting them,
re-stocking them, scrap costs for PWBs, etc. and then add those costs
back into the total amount spent on circuit boards at the end of the
year. Go back over all of the SCARs issued to that vendor.

Insist that that amount be removed from whatever "savings" were realized
by your purchasing department going to cheapo vendors. Compare these
numbers with the "good" fabricators.  Run it up the flagpole, issue
reports to your company's top management, etc.

As Dewey would say, this type of good behavior shall not go unpunished.

We put a lot of money and effort into material and finish selections in
the RoHS chageover.

We have strict specifications on our fabrication drawings.

We have previously fully qualified 3 high volume and 2 prototype PCBs,
and maintain them in a world wide AVL.

but purchasing sees pennies.............

This is just a proposed vendor - only sample quantites assembled, we
haven't ordered anything yet (I hope).

So far the proposed vendor has:
claimed to be a fabricator, but is actually a broker fabricated at two
shops, neither was included in the site visits or D&amp;Bs switched the
laminate we approved (twice) changed layer spacing used some alien
plating material performed microsectioning and solder testing on a
non-RoHS PCB, but shipped a completely different (hopefully RoHS) panel
The other (passed) microsection showed innerlayer separation.
Shipped PCBs with soldermask on pads.

Best scenario is that this finally wakes purchasing up to what I've been
telling them about buying boards in China.  Worst case is - they buy
these anyway.
