SpletThe Most Common PCB Copper Thickness in Manufacture. The most common unit of measure for the copper thickness on a printed circuit board is ounces (oz). But most of people have no idea about how thick is it. It's the finished thickness when 1 oz copper is pressed flat and spread evenly over a one square foot area, which equals 1.37 mils. SpletThis design tool is based on the charts in IPC-2221. First, the Area is calculated: Area [mils²] = ( Current [Amps] / (k* ( Temp_Rise [°C] )^b) )^ (1/c) Then, the Width is calculated: Width [mils] = Area [mils²] / ( Thickness [oz] * 1.378 [mils/oz] ) For IPC-2221 internal layers: k = 0.024, b = 0.44, c = 0.725.
