Current on a PCB
Mike Witherden email (remove spam text)
Hi I must say that one of the ways around this problem is to use Current Shunts
soldered or bolted (or both) to the track. These Current Shunts may be copper
wire, copper rods or copper bars (square or rectangular.) My favorite are the
copper common and earth bars used in mains DBs.
Some of these have holes drilled at regular intervals giving you an ideal way
of connecting large cables to your PCB.
This enables hundreds of amps to effectively flow on your PCB with no overheating problems.
Another, not so neat, Current Shunt is old solder wick!
(These Current Shunts also act as great Heat Shunts)
