I use Eagle Cad 6.4 to prepare PCB layouts then manufacture them at home. As I use amateurish equipment and method, I would like to have bigger pads as much as possible so that when I drill the pad holes, I will have a very large ring of copper around the hole to solder. It would be convenient to have bigger pads (when it is possible on the layout). I can do it on photoshop for sure or maybe by redefining each component's packet description on the library, but it is a little bit time consuming. I wonder if there is an easy tool like change tool to enlarge the pads I want.

The pads I'd like to enlarge are the green circles below image. For example, the diode (the most left circle ) has a bigger pad area, where as the resistors (the closest two green circles) have thinner circles.

When I drill these holes, sometime the drill takes the copper away and I'm left with rings that are too thin. For example, please see the below photo. These pins are not important but in some cases, it would be better to have a larger copper area. Is it possible to do it on Eagle Cad 6.4?

• You can't set the thickness in Eagle. Even if you could, it would not be for individual pads but for the board, or at least that layer, as a whole. You tell the board house you want "1oz copper", "2oz copper", or whatever. In your case it depends on the copper thickness of the stock you get. – Olin Lathrop Jul 7 '13 at 16:22
• Now you are really confusing things. It appears you mean the diameter of the pads, but you explicitly say you do NOT mean the diameter of the pads. Giving up. – Olin Lathrop Jul 7 '13 at 17:18
• The pad (green circles) are made of traces. 0.6 mm or 3.5 mm diameter drill radius would not enlarge thickness of the trace, the thickness is the same. I want to enlarge the thickness of the trace that creates the green circle. Therefore I do NOT mean the diameter. I hope it is clear now? – Angs Jul 7 '13 at 17:25
• No, you DO mean the diameter of the pad. And again, this has nothing to do with the thickness of the copper. The first time I can attribute to unfamiliarity with English, but if you keep doing it after this was explained to you then it's just wrong. Do a HELP DIAMETER in Eagle. – Olin Lathrop Jul 7 '13 at 19:31
• Pads are drawn by the CAD software as a circle, with a hole in the middle. It's not a circular trace, so you're thinking about the mechanics of making the pad larger incorrectly. – Connor Wolf Jul 7 '13 at 21:12
