4 Frequently Asked Questions about “Capacitor Screening Criteria”
Can DWV test reveal defective capacitors?
Experience shows that the effectiveness of the DWV test to reveal capacitors with defects is low; however, a comparative analysis of distributions of VBR before and after stress testing can reveal the presence of defective parts. 3/ In addition to C, DF, and IR measurements, VBR is measured using a technique as in Gr.1.
What are the requirements for monitoring open and closed circuits?
All open and closed circuits shall be monitored per MIL-STD-202, Method 310 or equivalent. There shall be no opening of closed contacts or closing of open contacts in excess of 10 microseconds. Vibration shall not result in any broken, loose, deformed or displaced parts.
Do SCD devices need a pre-cap inspection?
SCD devices require pre-cap Inspection. DPA can be substituted for pre-cap inspection. Class M or Non-JAN Compliant parts (with SMDs) are acceptable as a level 2 part only when a Class Q (or B ) microcircuit is not available. Otherwise, the Class Q (or B) level part should be used.
Which microcircuits are acceptable with additional testing?
Class Q (or Class B) microcircuits are acceptable with additional testing as level 1 parts only when Class V (or Class S) microcircuits are not available. Otherwise, the Class V (or Class S) level parts should be used.
