tractive system on PCB - "under coating"?

Hi,

in the FSAE rule EV4.1.7 for tractive system voltages on a PCB there is a table with minimum required spaces. One coloumn with min. spaces has the title "under coating". What does this "under coating" mean? Is solder resist such a "coating"?

Thanks,

Best would be to ask the official judges through your team login.

Hi,

the word missing in the rules is "conformal" - see here for explanation. That´s at least what standards I know refer to. There´s multiple companies producing such "conformal coatings" and some are avilable as spray can so you can apply it on your own. I´m sure customer support of one of them will be happy to advise you a product and send you a sample of it ;)
