Have you posted any Photos or Specs of your controller and driver PCB on this forum ??? If not could you ??? Clamp your MOSFET's to the bus bars for testing or assembly ???

By "clamp" I mean using spring heat sink clips e.g. MAXCLIP08G. We clean the back of the MOSFET, polish the bus bar, spread a little anti-oxidant grease, and screw down using a hole drilled and tapped into the bus bar.
Each MOSFET has the tiny gate drive connection board slid onto its leads, then the source pin is soldered to a tinned copper strip that makes the connection to the adjacent bus bar.
I think I've posted the board outline of the gate driver and STM32 controller boards before, but I'll do it again this evening if there is interest.
Update: Here is the post with the gate driver board.
