A.4.3
A.4.3 Inspection conditions. Unless otherwise specified in the applicable test method or procedure, inspections
and tests shall be performed in accordance with test method number 1.3 of IPC-TM-650.
A.4.4
A.4.4 Printed wiring board performance verification. Printed wiring board performance verification shall consist of
inspections on the production printed wiring boards and the QCTC or test coupons referenced in tables herein for in-
process, groups A and B inspections. Selection of test coupons for testing shall be in accordance with the applicable
inspection table. Each production printed wiring board or panel of printed wiring boards shall include sufficient test
coupons to complete the applicable verification requirements specified. The design of test coupons shall be as
specified on the applicable master drawing (see A.3.1.1). The minimum number of test coupons on the production
panel and the requirements for positioning the test coupons on the panel shall be in accordance with the requirements
A.4.4.1
A.4.4.1 Verifications preformed by a certified suitable laboratory. Because of the performance nature of this
document, the design and construction details of the printed boards, or the test coupons that represent the printed
boards, shall be supplied with the sample units to be inspected or tested by a certified suitable laboratory. The design
and construction details are needed so that the resulting evaluations can confirm compliance to both the master
drawing and the acceptability requirements herein. This communication of design and construction details shall apply
whenever printed wiring boards, panels of printed wiring boards, or test coupons are tested and inspected to either
group A (including electrical testing) or group B inspection herein performed by a certified suitable laboratory.
A.4.5
A.4.5 Qualification inspection. Qualification inspection shall be performed at the manufacturing location and a
laboratory acceptable to the Government (see 6.3) on sample units produced with equipment and procedures
normally used in production.
A.4.5.1
A.4.5.1 Qualification eligibility. The fabrication of the qualification test vehicles may begin before authorization to
test is granted; however, before the start of qualification testing, the manufacturer shall receive authorization from the
qualifying activity.
A.4.5.2
A.4.5.2 Samples.
A.4.5.2.1
A.4.5.2.1 Qualification test specimens. Qualification test specimens shall conform to the following for the type of
printed wiring boards for which qualification is sought:
a.
Type 1: The qualification test specimens for type 1 shall meet the requirements specified on DSCC Form
19W and the hole locations and conductor patterns of master drawing IPC-100041.
b.
Type 2: The qualification test specimens for type 2 shall meet the requirements specified on DSCC Form
19W and the hole locations and conductor patterns of master drawing IPC-100042.
c.
Type 3 using thermosetting resin base materials: The qualification test specimens for type 3 using
thermosetting materials shall meet the requirements specified on DSCC Form 19W and the hole locations
and conductor patterns of master drawing IPC-100043.
Type 3 using thermoplastic resin base materials: The qualification test specimens for type 3 using
d.
thermoplastic materials shall meet the requirements specified on DSCC Form 19W and the hole locations
and conductor patterns of master drawing IPC-100044.
e.
Type 3 alternative: The qualification test specimens for type 3 using thermosetting resin base materials shall
meet the requirements specified on master drawing IPC-100047.
If design defaults are not listed on DSCC Form 19W, then the values specified in IPC-2221 shall apply. See
modification to the requirements of IPC-100041, IPC-100042, IPC-100043, and IPC-100044 specified in A.4.5.2.1.1.
