WC,
This is not proper or legal. It takes more than Group A, In-Process and
Microsections to be listed on the QPL.
First, one qualifies the manufacturing process by producing and testing the
test boards required by the specification. The testing is done by a
laboratory that is qualified by DSCC. For 55110 these are Group C tests.
Second, in any month where production occurs, the most complex sample is
sent out for Group B testing. These tests go above and beyond what the Group
A tests require.
Paragraph 3.2 of MIL-PRF-55110 is very clear "the manufacturer shall certify
for QPL before contract award."
3.2 Qualification. Printed wiring boards furnished under this specification
shall be products that are authorized by the qualifying activity for listing
on the applicable QPL before contract award (see 4.3 and 6.3). In addition,
the manufacturer shall certify for QPL or receive certification from the
qualifying activity for QPL/QML that the product assurance requirements of
3.3 have been met and are being maintained.
Company A does not meet any of these criteria. The boards are not compliant.

Subject: [TN] QPL question
Company A, who is "not" on the QPL receives an order from a customer for a
product to be certified to current revision of MIL-PRF-55110.
The customer is informed that company A cannot accept the po nor can they
fabricate this because they are 'not' on the QPL. The customer does not
care, just want board fabricated with the proper documentation.
On the direction of the owner, Company A (not on QPL) fabricates the
product anyway, then they send it to company B who "is" on the QPL to
perform and generate the Group A, In-Process, and Microsection activity, the
product ships from company B, but is billed by company A.
Is this legal? proper?
