Re: gEDA-user: Cutouts



I'm not sure what to make of this part. If this is the only info you have on this part, I wouldn't use it until I get one in hand. It looks to me like this is intended for the body of the part to sit in the plane of the board with pins along the edges. Notice the drawing shows the edge of the PCB being cut back for the part. The three pins have two outlines, an inner and an outer one (I've got no idea what that means). The two rectangles at the top look like surface mount tabs to me. That is a very strange way to mount a part, especially in the center of the board. Is that what you see?

I think this drawing can only be properly interpreted if you have a clear idea of what the part looks like.

That is the link. I'm not too worried about cost. I'm really wondering how to create the footprint that has the cutout in it.

If they are large enough (somewhere in the range of 0.1 or 0.2 inches wide or more) they can be routed, but that often costs a bit more. A small rectangular pin is typically accommodated by notching the edge of the board, but if you want it in the middle, that would be a long notch.

In fact, I fudged the sizes a bit so I didn't have lots of different drills. My power connector (may be similar to yours) used five rectangular electrical pins and one alignment pin. The round holes seemed to work just fine. CUI jack barrel 5.5x2.1 mm PJ-051AH
