I am developing a cost sensitive product. The printed circuit boards need to be programmed and tested. It seems like a waste of money to put a programming/test connector on the board just to use it only once.
Ideally, I would just put down some through hole test points spaced 50 mils or 100 mils apart, plug something into it, and then remove that device when I am done programming/testing.
Is there some kind of connector that has little spring contacts that fit in a 30 mil or 50 mil through hole test point? Something like a row of really tiny banana jacks?
Over the years I recall having seen various crimp connector pins with springy contacts that probably would fit into holes on the order of 50 mils or so, but I can't recall what they were called and if I have ever seen them arranged into something like a single row 100 mil connector strip.
I know pogo-pins exist, but those are meant to press against a SMD pad. I would need to build a fixture for that to work, and I want to avoid that unless I have to. Something that just plugs into the holes seems like it would be simpler.
