3.9 Workmanship. Semiconductor devices shall be processed in such a manner as to be uniform in quality and
shall be free from other defects that will affect life, serviceability or appearance.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a. Qualification inspection (see 4.2).
b. Screening (see 4.3).
c. Conformance inspection (see 4.4).
4.2 Qualification inspection. Qualification inspection shall be in accordance with MIL-PRF-19500 and as specified
herein.
4.2.1 JANHC and JANKC devices. Qualification for JANHC and JANKC devices shall be as specified in
MIL-PRF-19500, appendix G.
4.3 Screening (JANS, JANTXV and JANTX levels only). Screening shall be in accordance with appendix E, table
IV of MIL-PRF-19500 and as specified herein. The following measurements shall be made in accordance with table
I herein. Devices that exceed the limits of table I shall not be acceptable.
