Comment: Great set of links. I ended up going with Telatemp because I needed something sensitive from 45-50C, something none of your listed suppliers were able to do. Still this gave me hope that I was searching for the right thing and that possibilities were out there. Thanks.

Comment: Hello Larry, You are welcome. Actually, that's exactly what I bought those film sheets for -- finding shorts in PCBs. I actually had to get the paper backing and adhesive off the sheets -- used Goof Off! Do it outside! For finding shorts, you need 20-25, and 25-30 deg C sheets. 4x6" or 4x4" are preferable over larger sheets. To not have your fingers heat up the sheets, use gloves or a piece of a plastic to press the sheet over the board, and apply a little pressure while rubbing. You will need 5-10A power supply. Start very slowly. Reach 0.5A slowly, while making sure to inspect whole board before each current increase. Then go up if short does not appear.

Comment: Michael, thanks so much for the links. Previously to seeing this, I had only located the Omega site selling the adhesive-coated sheets. Now I have a few companies to choose from. I need to buy some sheets of liquid crystal film, for diagnostic purposes. Actually I want to use it in assistance of locating shorts on a circuit board. Which is so much cheaper than buying a good IR camera for 3k or 4k USD. Thanks again; Larry C
