Variable track width and spacing

lima7 wrote on Tue, 01 November 2011 05:16

Is it possible to configure Eagle to increase the track width and

spacing when there is plenty of space available? I appreciate that when

routing between pads or around other components tracks have to get pretty

close to each other, but Eagle seems to be quite happy to route a couple

of very thin tracks right next to each other even when there is plenty of

space available. I've just started using eagle and will be etching my own

boards, I know from experience that making your own boards can be hit and

miss affair, and I'd like if I can, to keep the tracks reasonably wide

and well spaced whenever possible.

The auto-router will always use the width specified by the net class

associated with the signal/net.  But it will always use the minimum

required.  It does not have the capability of using minimum when it has to

and a default value when it can (like Alitum does).

When manual routing, you can make any trace segment any width you want.

The DRC will flag anything too narrow (based on net class/DRC setting) or

any clearances that are violated but you can make it as large as you want.

HTH,

James.
