Not to make a pest of myself but I have another question on my remote
light switch system.
In laying out the printed circuit board, how do I figure the trace width
to carry the required power? I figure the +12V buss will have to
carry about 15A max but want to double that for a safety margin to say
30 amps. Total length of the trace is about 3" and the board will be 2
oz (2.8 mils) copper. The limiting factor is clearance to the pins. Is
that possible or do I need to go to wire?
I'm building a 45' cutter in strip/composite. Watch my progress (or lack
there of) at: http://www.rutuonline.com
