I have built 6 QRP Class D/E type of PA kits (QCX, QDX, and QMX) that use the board as a heatsink and did not see this excess solder on the board.? I was surprised, as the quality has been much higher in the past.
?
I will use some paste and see what happens.? I have another QMX+ on order in case it has problems.
