I am trying to build a simple capacitor bank containing 40 of 47nF 2000V MKP type capacitors. Instead of conventional PCB manufactoring I prefer to mill the PCB because there are only holes to drill.
(Think of 40 MKP type capacitors connected in paralel and placed on a copper FR4 board.
PCB is has a very large area but has no routes rather than holes.
My main concern are the thermal pads for soldering I dont want to mill thermal pads around the holes .
because: The number of modules are high and I dont like thermal pads for high current pulse signals.
What can I do except milling thermal pads around the holes?
I plan to solder the boards wit a wave soldering machine.
