Electronics Forum / CAD / February 200520 Ga. Wire
Hello everyone, I have to make jumper pads for 20 Ga wire jumpers. The spec for the wire is 32 mils ( .812mm). Should I just go one size larger (18 Ga.. 40 mil) or larger? I appreciate everyone's advice. Ivan > Hello everyone, > [quoted text clipped - 5 lines] > > Ivan Always leave at least 5 mils minimum of "slop"; 2 mils for hole tolerance and 3 mils for easy insertion (or removal if rework is needed). 40 mils is fine. Robert- Thank you! >> Hello everyone, >> [quoted text clipped - 10 lines] >needed). > 40 mils is fine. As a rule of thumb, I just up the diameter from 25% to 50%... With 50% being used on small wires, and 25% on large wires. Don't just add a fixed amount of oversize because on larger wires you will find they are too tight to rework, and smaller wires the parts are too loose. -Chuck > Hello everyone, > [quoted text clipped - 5 lines] > > Ivan |
