Hi guys,
To answer some questions, Yes the face of the mosfet/diodes are touching the heat-sink, and the back with the metal is contacting the PCB for higher current capability. I loaded each mosfet and diode with a very fine aluminum particle grease thats meant for conducting heat. Im not sure how well the controller will work like this, but its not that hard to flip the components around to allow the metal back to contact the heat-sink. The problem with that though, is you still need to use the rubber isolation/heat transfer tape. If somebody wants me to build them one like that instead that can be arrange without changing very much. Should only take a few minutes.
I have also thought about liquid cooling it. It would not be very hard to machine a water block to mount to, instead of a heat-sink.
I have thought about paralleling 2-15 pair controllers back to back on one water block to create a monster 1800A controller. I still have to work out all the current sensor details, but I have hopes.
