A solution for the TMP36, using a female bullet crimp, opening up both ends and drilling a hole through it. The wire is rated to 200 or 300 degrees. Next step is to heat up an A600 scrap board and see what melts, then the A4000, wouldn't relish the idea of having to remove the coprocessor slot or the bridgeboard sockets.
First temperature test on A600 board, the cookie tray it's sitting on started to buckle so I will need to get a proper 3mm+ steel plate, possibly 5mm.
