Relationship between Copper Weight, Trace Width and ...

Relationship between Copper Weight, Trace Width and Current Carrying Capacity. Theoretically, PCB (Printed Circuit Board) current carrying capacity is determined by cross-sectional area of trace and temperature rise. Furthermore, cross-sectional area of trace is directly proportional to trace width and copper thickness.

How Copper Weight Impacts PCB Board Manufacturing

Nov 18, 2013 · One of the critical steps when ordering a printed circuit board is specifying the copper weight. Finished copper thickness on the printed circuit board is an important aspect of PCB design. The thickness along with the width of the trace is the determining factor in the amount of current (amps) the circuit can carry.
