Custom pads...

Hi there

 

I need to make a pad for this kind of pin:

I have made it like this:

Is there a better way to design the pad than this? it is a combination of a

bottom SMD and two pads.

Perhaps the con-faston is something for you.

I know the lib, but it is not suiteable for this design.

Is it not possible to design a custom pad in eagle?

In the pad i designed above, DRC is complaning about overlap (pad on a SMD)

but i dont know how else to do it when I want a different shape than the

given pads.

I posted asking the same question. I found a post in some electronics

forums which claimed you can avoid the DRC errors by moving the SMD pad

to another layer but it gave no real details. I've searched and search

but I can't find the link again.I did find this post which indicates it

is possible:

I am mounting the power switch on my pcb board. The terminal is in

rectangular shape but the pad in eagle is round. Is there a way to

create a custom pad shape?

Not without a fair bit of trouble. You will have to find a board company

that will cut the hole out for you. Most people accept the round hole,

unless it's obviously a bad solution.

Thanx. I think I will stick with what i got so far.

What about miling 2 short slots (using layer 46)? This was often discussed

earlier in the groups. Talk to your boardhouse. Individual shape of pads is

long on our wishlist ...

Yes, this is really needed somewhere down the Eagle versions priorities

list. I asked about this a while back, and the only solution was to use

polygons to create the copper layer "drawing" around pads or pins, such as

might be needed when a custom shaped copper heat sink must be copper

connected to a pad or pin with or without using a trace (perhaps for

impedance reasons). The price is having to tell Eagle to ignore the DRC

"overlap" errors (i.e., "approve" them), but I think the approvals are

persistent between sessions of a newly loaded existing project unless the

affected part gets removed and then put back into an existing project.

Still, I think it best practice if the library designer includes a note in a

library doc layer, and the library preview itself, indicating which DRC

"overlap" errors must be approved for a device package used in a project.

==> It would be nice if the library itself could somehow keep a designer

specified list of allowed overlap errors and DRC could look at that library

list and automatically approve them.
