Post by thread:[EE] Eagle newbie question

I've got a question about the following picture: http://www.ls1m.com/demo/eagle_r1.JPG This is a resistor on my first attempt at a circuit board, using Eagle. I think I've figured out that the green is the solder pad (on the bottom side, I assume), the cross-hatched octagon is the solder flow area, and the yellow circle is the drill size. If that's true, then how can the drill size be bigger than the solder pad? How do I fix it so the hole is smaller or the pad is bigger, without building my own library symbol? Thanks -Mark

It's not the drill size - it's a drill bit positioning guide. Turn off all the layers (Tools->Layers or View->Layers iirc) except Top, Bottom, tPlace, bPlace and Dimension. The green donut is the pad, the drill hole is the hole in the middle of the donut.

Ah. That makes more sense. It confused me because the yellow circle shows up on either layer holes or drills - don't have it in front of me right now. Btw, as an Autocad user, I find Eagle very easy to use. Love the way you can type the commands in. One more question. I need to send this in to be prototyped. I was looking at pcbexpress.com; they'll do a simple 2-layer board for $80. Anyone have experience with them, or a better company to go with? Thanks. -Mark --- .....philpemKILLspam@spam@dsl.pipex.com wrote: {Quote hidden}> "Mark Chauvin" said: > > > and the yellow > > circle is the drill size.

OK I lied. I have another question. When I layed out the board, I used the autorouter to place the traces, then moved some around the way I liked. All the settings for the autorouter were set to the defaults. Are there any particular settings that I should change or tweak? This is a very simple, 2-layer through-hole design.
