How to make footprint for a jack with rectangular tabs?

of pins that go through circular holes, it has tabs that go through

rectangular holes. How do I do this in the footprint editor?

 

Draw the rectangles or wires in the milling layer and ensure you include and

explain the presence of the routing layer to the board house

Verify the dimensions of your slots are greater than the minimums of the

board house.

Take guidance here from the board house you intend to use.

Also, the jack has five round pegs that appear to be for positioning.

Is there a way to indicate this on the footprint in such a way that

they will be drilled no matter where I place the jack (as opposed to

putting holes on the board that would have to be re-positioned if I

moved the jack)? I suppose that I could make them fake pads - so what

if they get plated through? - but is there another way?

Place "holes: when you design the package. They wont be plated through and

copper pours will keep away from them as determined by your DRC settings

You could use pads if you see some advantage or use a cheap board service

option that does not offer un-plated holes (Its an additonal later stage

they remove to keep the cost down)

Or maybe I

will just ignore the pegs and let the piece sit 1 mm above the board.

But I fear that the pegs are important for handling the stress of

plugging a phono plug in and out all the time.

 

Finally, how are these pieces soldered in? Do the tabs have to be

folded over before soldering? If so, this has impications for the

board design too - there has to be a pad on the back side but only on

one side of the hole.

Usually the tabs are given a twist to hold the part in place for manual or

wave soldering
