SAE AS6294/1

Description / Abstract: This document establishes common industry practices and recommended screening, qualification, and lot acceptance testing of Plastic Encapsulated Microcircuits (PEMs) for use in space application environments.

Purpose

Plastic encapsulated products have been used based on testing and analysis for high reliability applications such as those for Medical, Military hardware and in Space applications. There are some complex Electrical, Electronic and Electromechanical (EEE) products that may only exist in plastic packages and have been risk mitigated for the intended applications. However, the industry has different ways of screening and qualifying PEMs. This document was created by a subcommittee of SAE SSTG G12 to standardize a PEMs flow and address possible future extension of the QML system to include PEMs for space. The committee has utilized existing documents such as NASA Goddard PEMS-INST-001 (Instructions for Plastic Encapsulated Microcircuits (PEMs) Selection, Screening, and Qualification), NASA EEE-INST-002 (Instructions for EEE Parts Selection, Screening, Qualification, and Derating), NASA Marshall Space Flight Center MSFCSTD- 3012 (EEE Parts Management and Control Requirements for MSFC Space Flight Hardware) and SAE SSB-1 (Guidelines for Using Plastic Encapsulated Microcircuits and Semiconductors in Military, Aerospace and Other Rugged Applications), as well as reviews of multiple industry practices. In many cases, MSFC-STD-3012 (Revision A, dated 2/12/2012) was used as the baseline for this document.
