adding PCB mounting holes in Eagle

rjm · 21st April 2005, 12:40 PM

dumb question but...

How do you add 3mm mounting holes to the layout diagram? I seem to be limited to wire pads of much smaller dimensions.

TIA

Hi,

there's a library 'holes' that contains many different diameters, both with and without a copper ring (that can be connected to any signal).

Thanks.

One more question:

For single sided boards it is desirable to have a large pad size, say 70mils for through-hole components, right?

The resistors in Eagle all seem to have small pads, maybe 50 mils or so. Fine for double sided, I suppose, but a bit dicey for single sided with no plating on the through hole.

Does anybody worry about this? Is the only solution editing the component libraries?

Your concerns are well founded. The older Eagle libraries had larger through-hole component pads that are more suitable for single-sided boards or hand soldering.

Here you have standard elements library with bigger pads for version 4.X

1a.lbr library includes some capacitors which are a better substitute than the stock Eagle library, but unfortunately no resistors over 7.5mm lead spacing are to be found.

I'll try editing the libraries myself, then.
