SEM-E stands for Standard electronics module format E and is a Military standard module in format E particularly for avionic applications. The objective of the 'Advanced SEM Processes' effort was to simplify the development and qualification processes and reduce the related process times and costs from the current way of doing business. The object was to define new processes for development and qualification that used existing commercial and military technology in applying 'MultiChip Modules' (MCM's) to (SEM-E) packaging. The primary objective was to reduce the current development cycle time from three - five years to twelve months and costs from $500,000 - $1,000,000 to $100,00 - $250,000, therefore providing a baseline for standardizing electronics hardware acquisition processes into the twenty first century and beyond. One configuration is a standard electronics module (SEM-E) frame that fits a 3/4-width standard air transportable rack chassis. This configuration must have a backplane interconnect because of the chassis type.

This is the Company’s first SEM E Module produced in about 1984. It is missing the 1553, NED, 8086 and Graphics Processor chips.
