Quality Conformance Testing

   

Unlike standard commercial products, HiRel products must be submitted to various levels of quality conformance testing to ensure that the products are capable of performing to specifications in the often harsh environments of military and space applications. Both the United States and European community have each developed specifications that detail the sequence of quality conformance testing.

In the United States, the Defense Supply Center Columbus (DSCC) is the controlling agency and has issued specifications that govern the quality conformance testing sequence performed on semiconductor devices and hybrid modules, namely MIL-PRF-19500/MIL-STD-750, MIL-PRF-38534/MIL-STD-883 and MIL-PRF-38535/MIL-STD-883.

MIL-PRF-19500/MIL-STD-750 are the controlling specifications for discrete semiconductors such as diodes and power MOSFETs. MIL-PRF-19500 directs discrete semiconductors to be manufactured to either JAN, JANTX, JANTXV, or JANS levels (Note: the JAN level is not allowed for MOSFETs).

International Rectifier HiRel Products Group manufactures and tests hermetic products to one of three distinct quality conformance levels: (1) commercial hermetic, (2) source control drawing (SCD), or (3) MIL-PRF-38534, MIL-PRF-38535 qualified. The HiRel Products Group also provides screened plastic encapsulated devices.

Glossary

Class H: Class H is the standard military quality level provided in MIL-PRF-38534, General Specification for Hybrid Microcircuits. It is intended for space applications.

Level B: Class level B defines the screening requirements for high reliability military applications as specified in MIL-STD-883 and is intended for use in class H products.

Level S: Class level S defines the screening requirements for high reliability space applications as specified in MIL-STD-883 and is intended for use in class K products.

JAN: JAN (Joint Army Navy) is the prefix assigned by the DSCC to designate devices on the DSCC qualified parts list.

JANTX: Military screening level as specified in MIL-PRF-19500 for a DSCC qualified device.

JANTXV: Military with visual inspection screening level as specified in MIL-PRF-19500 for a DSCC qualified device.

JANS: Space level screening as specified in MIL-PRF-19500 for a DSCC qualified device.
