Eagle footprint for Dean Connector

Former Member

Hi,

I was wondering how to make a foot print for a connector (Dean Connector) as shown below. Each blade is about 0.150 inch.  Thanks

    Those kind of slotted through-hole pads are kinda tricky with Eagle,

    especially with more than 2 layers. (I hope eagle will support through hole

    milling one day, its well over due).

     

    The way I do it is to define a normal circular pad, then draw polygons of

    the wanted pad shape on each layer, and I use a custom layer for

    through-hole milling. One of the problems I get is that I had to draw the

    polygon shape on every of the 16 layers to make it work for any stackup, and

    when only using a few of the layers, I get LOTS of errors on the layers not

    in use. Also, for some strange reason, current Eagle version forces all

    these layers visible after a DRC. If you define the part specificly for a

    specific stackup, you should be fine.

     

    Back in the days I got burnt by using oval shaped pads with curstom through

    hole milling. I was filling with GND in mid layers, and the manufacturer was

    not able to warn me that the through hole milling was causing unwanted short

    circuit, so you need to be extra (manually) careful with this.
