Subject: Junction Temperature
Message:
Based on thermal analysis, measurement and thermal resistance given by IC manufacturers, we've estimated in our developmental systems, some of the junction temperature of the commercial grade ICs have exceeded the maximum junction temperature of 150 degrees. We're thinking of changing these ICs to industrial grade. However, is there any difference in the junction temperature for commercial and industry grade ICs ?
