Re: Yet another article (with pics) on QCX Mini regulator replacement #qcxmini #magicsmoke

Very nice "cooling" article. You probably should put some thermal compound between the FETs and the large solder pad on the circuit board, as that's the primary heat sink for those transistors. The washer just holds the FETs in good contact with the board and has minimal contact area due to the rounded backs of the FETs.
