C carmusic New Member Apr 25, 2008 #1 Hi i am presently designing a pcb and there will be 375V dc input, The pcb has solder mask. what should be minimum trace clearance for it to comply with safety agencies? is 30-40mil ok?

M mneary New Member Apr 30, 2008 #2 is 30-40mil ok? Click to expand... No. It depends on your application, but it probably won't be smaller than 4mm (0.160").

C carmusic New Member Apr 30, 2008 #3 it is for a dc/dc converter, i'll will check power supply pcb to compare
Boncuk New Member Apr 30, 2008 #4 To comply with CE-rules the trace distance should be at least 7.5mm (~300mil). For more board space and only if a solder mask is applied you may reduce trace distance to 2mm, keeping them apart 7.5mm at terminals. Boncuk
