Hi Joe,

We use Loctite 495 or 416 with the 712 accelerator (we have a T/C welder in case they break upon removal). We also use an IR probe which connects to the multimeter for those hard to get locations.

Subject: Thermocouple issues
Date: Fri, 15 Dec 2000 14:52:45 -0500



        I am in the process of performing a thermal evaluation and am using
thermocouples to measure surface temperatures of IC's, etc.  I'm finding
that the thermocouple tape that I'm using tends to experience a degradation
of the adhesive as the temperatures increase (in the 80-100°C range) causing
the thermocouples to separate from the surfaces.  I'd appreciate any advice
that could point to a higher performing tape/adhesive for such an
application.  Some of the IC's are quite small which doesn't leave much
surface area for adhesion and I am using as many as 40 thermocouples per
card.

Thx,


Joe
