Hi Jack,
There is a free program that has been put out by Saturn PCB Design that has calculations that give the Power, Current, Voltage, etc of traces on a board. It takes into account the copper thickness, material, Temps, plating, etc. I like this calculator, but I’m not exactly sure what each of the calculations may be based upon. We have found one calculation to be questionable and they were VERY prompt in replying to us and making the correction. Have you looked at this or talked with the owners? And if Saturn employees are lurking – thank you for a very useful program.

Subject: Re: [DC] Is Fusing Current Current?
wow.
Not even one reply?
Not even one additional reference?
Is this a subject no one has to deal with?
I'm SO disappointed....tsk, tsk, tsk,
Well, I suppose I should just go home.
seeya Monday!

Greetings all you lurkers...
Hey, I noticed someone over on TechNet was asking about fusing current,
which prompted me to re-read Doug Brooks extremely valuable 1998 article
on the subject
I just realized that this topic would be a perfect addition to the new IPC-2152
"Standard for Determining Current-Carrying Capacity in Printed Board Design",
and as long as I can put something together by May 1st, I can probably insert
it before its too late.
So my question is, does anyone else have any sources for this subject?
At the time, Doug wrote it purely from theory (no empirical data) but as far as
I know, no one has ever disputed the conclusions and the results have always
worked.
Doug, if you are out there, is there anything in your article you would edit after
these ten years? Any refinements?
currently,
Jack
