Introduction to High Temperature Electronics

Metro IMAPS Vendor Day

By Tom Terlizzi GM Systems November 19, 2013 Clarion Hotel, Ronkonkoma, N.Y

PURPOSE

◆  A BRIEF INTRODUCTION INTO THE WORLD

OF HIGH TEMPERATURE ELECTRONICS

2

AGENDA

◆  DEFINE HIGH TEMPERATURE ELECTRONICS

◆  DESCRIBE SOME APLICATIONS

3

WHAT ARE TYPICAL INTEGRATED CIRCUIT MILITARY OPERATING TEMPERATURE RANGES?

4

MAXIMUM JUNCTION AND STORAGE TEMPERATURE

150oC

MAXIMUM OPERATING TEMPERATURE 125oC

MIL-PRF-38535

DEFINITION OF HIGH TEMPERATURE ELECTRONICS?

◆  NO INDUSTRY STANDARDS OR AGREEMENT

◆  “ELECTRONICS OPERATING AT TEMPERATURES IN

EXCESS OF THOSE NORMALLY ENCONTERED BY

CONVENTIONAL SILICON-BASED SEMICONDUCTORS

OR THEIR AUXILLARY COMPONENTS.”1

◆  TYPICALLY >125oC OR >150oC BUT SOME REPORTED

LAB WORK TO 600oC.
