Hello All,
Have to much "Current" being draw on my PCB. Input Resistor burnt up (oops), my question is, how wide should my "Input Trace" be for 2 amp draw? I got some "google" data, but want to know from yall. Also, should the 5v Trace around my (4 x 3) be set to a minimum?
1) Input Trace (width)
2) 5v Trace around the PCB (width)
Just ordered 2amp input resistor and 5v 3amp regulator.
May add a 2nd 5v reg. to handle the Serial/Parallel Display(s).
Thanks for any insight/help
Howard

The only help I can think of is this web-based calculator - http://circuitcalculator.com/wordpress/ ... alculator/

Re: Trace width
Neat question: http://circuitcalculator.com/wordpress/ ... alculator/
On a board with 1.6 ounce copper 1.27mm will handle 2 amp on an internal layer and .488mm on an external layer.
With my DRC trace width set to .15mm I would need to build a net class for the net carrying the power to the consumer of that current.
And while I was typing Tomg beat me to the enter key!
Google is our friend....

Re: Trace width
This is my favorite free calculator. It uses the latest IPC-2152 standard for multilayer board (takes adjacent plane layers into account). It has lots of other related calculators as well.
