Abstract:

The availability of electronic parts rated for operating temperature ranges wider than -40 to 85^oC is decreasing as semiconductor manufacturers are driven by commercial applications such as computers and communications. The need for parts rated for higher temperature is growing for applications such as avionics, military, and automotive electronics, although their market share is insignificant. Efforts are therefore underway to devise methods for using electronic parts outside the part manufacturers' specified temperature range. This paper presents the "parameter re-characterization" method for part use outside part manufacturers specified temperature range. Step-by-step approach for parameter re-characterization has been presented along with the cautions that need to be undertaken for successful parameter re-characterization.
