4.6 Capability verification inspection. Capability verification inspection shall be in accordance with the TRB
approved capability verification inspection plan. The frequency of this verification shall be as a minimum every 2
years. Each base material type qualified shall be verified. The following tests and inspections should be considered
when accomplishing capability verification inspection: thermal shock, rework simulation, and moisture and insulation
resistance testing.
4.7 Methods of inspection.
4.7.1 Visual and dimensional inspection. The printed board specimen shall be inspected in accordance with test
method number 2.1.8 of IPC-TM-650, except that the magnification shall be 1.75x (3 diopters), minimum.
*
4.7.2 Microsection inspection. Microsection inspections shall be accomplished by using methods in accordance
with either test method number 2.1.1 or 2.1.1.2 of IPC-TM-650. The plated-through holes shall be microsectioned in
the vertical plane with an accuracy of +/- 10 percent of the center of the hole. A minimum of three holes shall be
evaluated per microsection.
4.7.3 Chemical test methods.
*
4.7.3.1 Cleanliness. The printed board specimen shall be inspected for ionic cleanliness in accordance with test
method number 2.3.25 of IPC-TM-650.
*
4.7.3.2 Elongation of copper. The test for elongation of copper shall be performed in accordance with ASTM E345
or test method number 2.4.18.1 of IPC-TM-650. The travel speed of testing shall be 50.0 mm ± 1.0 mm (1.97 ± .03
inches) per minute.
*
4.7.3.3 Tensile strength of copper. The test for tensile strength of copper shall be performed in accordance with
ASTM E345 or test method number 2.4.18.1 of IPC-TM-650. The travel speed of testing shall be 50.0 mm ± 1.0 mm
(1.97 ± .03 inches) per minute.
