Requirements for Plastic Encapsulated Microcircuits in Military and Avionics Applications
This standard documents and establishes common industry practices, and screening and qualification testing, of Plastic Encapsulated Microcircuits (PEMs) for use in military and avionics application environments.
Rationale: This document provides requirements for screening and qualification for use of plastic encapsulated microcircuits (PEMs) in military and avionics applications. The level of testing on PEMs depends on the application and reliability requirements of the system allocated to the PEMs. It is the responsibility of the user to have the tests conducted using the requirements specified herein. This document addresses many of the concerns associated with PEM construction and manufacturing, primarily the non-hermetic packaging and the supply chain situation of multiple material sets and assembly sites.
The approach to establishing PEM reliability defined herein leverages several existing industry standards, including AEC Q100, JESD47, MSFC-STD-3012, and SAE SSB-1.
