I am in need of building a lowcost magnetic board to board connector. There will be a lot of modules and a connector that connects both sides is needed 6x on each pcb.

I need a connection similar to this - 5x pogo pins on one side, 5 receptacles on the other side.

Board to board pogo pins

Has anyone tried using plated through-hole vias (castellated holes) as receptacles (female side) of a pogo pin? On top of that the pogo pins would need to be embedded in the pcb to be in the same height.

Thanks for comments, if this is a really bad idea.

I have something like these pictures in mind:

  • \$\begingroup\$ Never tried it... I could see it working, but you'd need your boards to be intentionally misaligned in the assembly. I've never seen mid-board-mount pogo pins. I suppose Mill-Max would make them for you if you're willing to buy enough of them... \$\endgroup\$

  • \$\begingroup\$ I want to use it as a kind of right angle connector. I think I would be able to use normal pogo pins soldered inside a pcb. \$\endgroup\$

  • \$\begingroup\$ and I would't need to misalign the pogo pins. If a choose a pin that is close to 1.6mm in height, it can be soldered inside the height of a pcb. \$\endgroup\$

    \$\begingroup\$ It's probably possible with castellated holes and plated slots to accept the pogo pins (and a jig to align them during hand soldering). The spacing would be relatively large. Reliable? Who knows. \$\endgroup\$
