KeepIS had special capacitor boards made for his build as he was using large screw mount capacitors. I was referring to the boards that would be supplied through me as part of the inverter project build that I presented here.
Re using JLCPCB to populate boards - personally I would use them if it was a surface mount board with many SMD components. For the through hole PCBs I try to maintain ability for home builds with many components being sourced from our parts bins. Also the many non mainstream parts (ie high current terminals) used in the inverter and non standard lead bends of the power Mosfets etc could be a bit of a challenge for them. Also not sure what documentation and pictures they would require for a project like this.
I go to a lot of trouble to ensure accurately aligned Mosfets to the mounting holes on the power PCB by using a long necked TO220 mounting bush and 3mm screws etc and ensure the 3 legs are pretty central to their pads, this is repeated for all 16 FETs. It means if I ever need to remove a MOSFET half the battle is already won if the legs are not under tension against the internal bore of the flow through joint, a few seconds with the solder sucker and they just fall out. I am confident that this sort of attention to detail would not occur with their builds, the low cost would not allow it.
