What is PCB Trace Width?
IPC-2221 Standard.
How it Works
Based on temp rise and current.
Example
Input: 1A
Result: 10 mil (approx)
FAQ
Temp rise?
Acceptable heat (e.g. 10C).
Copper weight?
1oz is standard (35um).
Internal layer?
Needs wider trace (less cooling).
Voltage drop?
Check for long traces.
Via?
Vias handle less current.
