I was intending to use the Lumberg 1503 02 3.5mm stereo jack connector on a PCB. After progressing some way through the design, I noticed that the pins for the connector are not on the bottom as I expected, but ~1.5 mm up the body. The rear pins also have a strange bend in them.
Based on the 3D model, I can identify three possible places where the connector could sit on a PCB:
I have highlighted the rear legs as they don't show up well otherwise.
From top to bottom, the green lines show possible PCB locations:
- The PCB sits flush with the pins. This required a cutout for the body as well as the rear pins where they drop down.
- The PCB sits flush with the lowest point of the rear pins. This required a cutout for the body and the front pins are in mid-air.
- The PCB sits flush with the lowest point of the body. All pins are in mid-air.
Option 1 seems the only viable choice, but the datasheet makes no mention of a cutout, only standard PCB pads and holes for the locator pins.
What am I missing and how do I correctly design a PCB footprint for this connector?
