I'm looking for the good practices to do PCB tinning to increase the current handling capability of traces on a power supply board.
My questions are:
- is there any table of the tinning width/thickness and the increased current handling?
- should the soldermask windows be aligned or perpendicular to the solder wave direction?
- is there a min/max/ideal width, should it cover the track completely or leave some soldermask on the edges?
- what about tinning ground planes to increase thermal?
