No, but it was a valid test, even if the temperature was "uncalibrated." > No, I don't know of any which are made out of a high temp plastic. > What is the application?

This is for capacitor testing of small boxed film parts. The reason we aren't using solder is because we are measuring specs with our LCR bridge up to 100KHz which needs the parts in a special fixture. A bread board is nice for a number of reasons, one of them being pre-made. I may have to go with a PCB and either socket pins or IC sockets spaced appropriately. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
