I need to pass high current on some part of my circuit. I used an online PCB track width calculator to see that required track width is about 5mm and minimum clearance is 1mm, which makes it about 7mm width at total just for one track. I need several of these high current carrying tracks on my PCB which will consume too much space to afford.
I am thinking of soldering copper wires on the top side of the PCB which will be parallel to the thin and symbolical tracks on the bottom side. But I would like to know if there is a more professional way of overcoming this problem.
Answer
High-current PCB bus bars are available from several suppliers, such as:
and are an ideal solution. A quick search for "PCB bus bars" will yield a number of suppliers.
