I have been working on my third board and have been stalled for over a year.
because of thermal pad issues. I have just started to see what is available. Some times the smallest things bog down my projects.
I have found digikey bergquist BER180-ND individual pads rated at 1.6 W/m-K for $0.57 ea. They may not conform to irregularities as good as a ber231-nd 1.5 W/m-K pad listed in the power BOM. They both have electrical isolation properties.
I an asking for coment and recomendation of one or the other for the 500 amp board.
Thanks 83 Subaru station wagon EV
has worked pretty good with salvage yard pb and a 2CM77 aircraft generator
