The CircuitCalculator Blog PCB Trace Width Calculator

Jan 31, 2006The circuit boards can be series joined up by soldering end to end. However I have to bottleneck down to 1.5 mm every time I join one circuit to another, and that 1.5mm track has to carry the 6A over a distance of about 1 to 1.5mm, but is directly on the flooded areas either side. Your comments would be appreciated. 112. Brad - May 29, 2007 Clive,
