High power PCB's

fr0st · 23rd February 2003, 07:50 AM

As a general guide, If I put bras plating on my PCB tracks how much would this increase the current handling of them?
Plating is about 0.5mm thick, tracks are approx 1cm wide
Is there a better way I can increase with power handling of the tracks without making them wider?

Solder a bus bar to them. You can use a piece of heavy gauge copper wire for a bus bar.

1 cm copper traces, 35 µm thick can take 30-40 A without fusing the traces. 70 or 105 µm can you also test. How many amperes do you have in your circuit?

About 75 @ full load.
I have a fair bit a 1mm copper winding wires. If i solder it onto the traces every cm or so along with iss act as the same thing right?

What is it? An amp? Think also that the half current will flow in all traces except for speaker output (if it's an amp). 70-105 µm will do the trick for you also soldering extra copper wire.
