PCB Trace Width Calculator and ANSI IPC-2221A PCB Trace Width Calculator belong to the tools introduced just now. Elements Determining Maximum Current Carrying Capacity Although a simple formula can be directly employed to calculate maximum current carrying capacity, practical cases are not that ...
Trace width Assumed temperature rise and conditions The tables relate width and weight to maximum current for common PCB parameters. An excerpt is shown below: Width (mm)1 oz Current (A)2 oz Current (A) 0.251.42.5 0.52.23.9 0.753.15.9 ...
If you have determined that your design requires more current than 1 oz can carry, you'll need to consider increasing the copper weight or increasing the width of your traces. Here is a link to a current calculator: http://circuitcalculator.com/wordpress/?p=25/...
