Hi Jason
At my former company I did lots of profiling. We had worked a lot with KIC
whom introduced me to the aluminum tape method to attach TCs. Please see
their paper "A comparison Method for attaching TCs to PCBs for thermal
profiling" on www.kicthermal.com. The study finds aluminum tape a reliable
alternative to high temperature solder. I also conducted a similar study
internally and found the same result. The aluminum tape is easy to use and
very reliable and repeatable. It is also an environmentally clean method
to profile boards.

What is everyone's (anyone's?) preferred method of thermocouple attachment?
Does anyone prefer soldered wires over aluminum tape? Or Temprobes over
epoxy? Also, is there any spec versus rule-of-thumb about alloys to use to
profile PCBs? Is there any concensus that SN96 is best to use when
profiling
SN63 boards? Or HMP to use when profiling SN96 boards? There obviously is
need when soldering probes to go over the liquidus of the PCB you are
attaching to, but by how much?
Any replies appreciated.
