Hi,
Last June, I posted about arbitrary pad shapes. I was eventually able to
solve my problem and go to fab on my board. There were 2 problems which
apply to the new issue I describe below. One is line width and the other
is placement of the arbitrary pad shape on the final layout.
My new issue is I'm using a device which has through holes which are
basically rectangles with rounded corners. I can create the hole using the
milling layer as described in the manual. The problem (again) has to do
with the arbitrary pad shapes.
There are a couple of issues:
- In my previous post, the device was an SMT so a single pad wasn't a
problem. But my board is 6 layers. It seems (to me, a complete Eagle
novice) that this is a big deficiency in Eagle. The reason is you need to
create the pad in each layer, making lots of work. Another big problem
with this is the pad is not associated with the library part. So if you
move the device, you need to move the pad in every layer you've built it.
Wouldn't it be better to build the pad in the library part itself and then
have Eagle place the pad in all the layers, as it does with "normal"
devices?
- Line width is still an issues. It seems that since everything inside of
the lines of the pad are the pad itself, then zero width lines should be
allowed. Then you could specify the outer limits of the pad, preventing
the pad from encroaching on other devices, without having to calculate how
far outside the line the pad goes, or whether the line width is going to
violate the design rules.
I expect that any responses to this will essentially be "Yeah, that's the
way it is. Deal with it." But any advice on how to make this easier would
be greatly appreciated.
Thanks!
Dave
