Help for footprint (edge mounted connector)

Carsten,

The attached isn't exactly what you want, but it should serve as a guide

on how to design an edge connector.  It's a 50-pin card edge connector

with three different configurations - left end of board edge, right end

of board edge, and middle of board edge.  As Richard mentioned, you will

have to work with your board house to specify the gold plating.

Note that zero-width wires are placed in the Dimension layer to specify

the cutout.  What's NOT in the design is a polygon or rectangle that

specifies the top and bottom finish.  Eagle has tFinish and bFinish

layers to specify exactly this.  You can add sections to your CAM job to

produce gerber files for these two layers, then name the output files

AuTop.gbr and AuBot.gbr.  That and a note in the README file should make

it pretty obvious to the board house which pads should be gold plated.

Argh!!!  I had to zip the file to get it to post - it's just a hair over

50k unzipped.

HTH,

Hello,

I'm doing my first few boards in Eagle, and so far everything is running

perfectly (and will upgrade to the full version now)

On a new board I'm trying to do I have two 6 pin connectors that I would

like to mount on the edge of the board (horisontal). I'm having a hard

time how to design that as a footprint. There needs to be to cutouts in

the board and these should be plated. I have attached a picture of the

connecotor and a picture of how it has been done in another product.

Any help out there ? This is the last thing I need to resolve before my

board is being sent (I'm using PCB-POOL)

 

Thanks for any help (would even consider paying you for a ready made

footprint that would do this if reasonable..)

thanks Chuck!

That did guide me in the right direction! I will have a talk with the PCB guys and see what they say about this.

Thanks for your help !

Chuck -

Very helpful library!

I am modifying your CARDEDGE-50 to be a 72-pin edge connector that I need.

I noticed that the odd-numbered SMD's in CARDEDGE-50 did not exclude stop and cream. That is, the did not have the stop="no" cream="no" attribute. See below.

All the other SMDs in the library did.

Is this by design, and, if so, for what reason?

<smd name="4" x="-27.94" y="5.08" dx="1.397" dy="10.16" layer="1" stop="no" cream="no"/>

<smd name="2" x="-30.48" y="5.08" dx="1.397" dy="10.16" layer="1" stop="no" cream="no"/>

<smd name="21" x="-5.08" y="5.08" dx="1.397" dy="10.16" layer="16" rot="R180"/>

<smd name="23" x="-2.54" y="5.08" dx="1.397" dy="10.16" layer="16" rot="R180"/>

I am making a simple extender card so I'm not sure it matters. But I certainly would like to know.

Thanks again for the great card-edge library!
