In figuring out the required conductor width, you can use the chart in MIL-STD-275, Rev. E (p. 34, Fig. 4a). This chart is used in determining current carrying capacity and sizes of the etched copper conductors for various temp. rises above ambient. _______________________________________________________________________________ Subject: Conductor widths From: Alan H Matsunaga Date: 4/10/96 4:43 PM I thought that one of you two could help here.

Thanks, Tom _______________________________________________________________________________ Subject: Conductor widths From: [log in to unmask] at CCGATE Date: 4/10/96 7:11 AM Help, We are laying out a power distribution board. We have current requirement of 35 amps and 15 amps. Our design is using 2oz copper, 2 layers, and 20 degrees temperature rise. I am not sure of the conductor width required for both 35 & 15 amps. Can anyone help answer this question? Any help would be appreciated....
