Need advice: Routing copper trace width
Hey, i'm in need of a rule of thumb when choosing the width for 1oz copper during PCB layout. I'm routing a pcb which is used in a 12W linear regulator.
I used to know about a rule which stated that for every amper going trough the trace you needed aprox x many mil of copper width. atm i can't remember what it was. So i was hoping some of you knew it or had suggestions. The trace needs to carry a maximum of 1A. The copper i have is 1 oz. Any help appreciated.

I've found this to be a useful site.
http://circuitcalculator.com/wordpre...th-calculator/ It is a trace width calculator that goes by the current IPC-2221 (formerly IPC-D-275). I have used the IPC specifications for boards for many PCBs.
