SOICbite ISP board-connector thingy
MarkR42:
Hi,
I just saw this and it looks amazing- a PCB footprint which can be placed on the edge of a board and mates with a cheapo soic8 test clip. Very space efficient and simple.

Has anyone tried it? Any thoughts?

Hi, I made the footprint. It's not the most secure contact with the PCB but I put one on pretty much all my boards now.
However, I'm clearly biased and this person has done a review recently, which might be useful to you.

Thanks for making it!
I've got some 1.0mm boards on order to test if this will work for my application. Hopefully it will work the same as thicker boards. I've bought a test-clip and I'm going to try it out.
If this works ok, I'll use it on the next batch of my boards, as it will replace using pogo-pins on to through-hole pads, it's smaller and less fiddly.

You're welcome!
I hope you noted from the linked review that on thinner PCBs it is less reliable and you may need to cut more of your clip away to make contact. Also, you may (and this can apply to 1.6mm boards too) need to press the clip ends together if you haven't made your clip spring apply more force in the closed position. There's a link in the readme.md in the github repo that shows the different areas that may need to be trimmed on the clip.
Also, for 1mm PCBs, you may want to consider removing the two outer "claws" on one "jaw"/side of the clip and the two inner "claws" on the other "jaw"/side. That way, if the claws would have met before the spring contacts had made contact with the PCB pads, they now won't, but you should still get the mating benefit of the "claws". Does that make sense?

I only need 4 signals, not 8, so I've spaced them out among the pins and arranged them in a way which means nothing Bad happens if they short with the opposing pins. I'm also not 100% sure that this capacitor here, won't foul on the sioc clip,
If needed I can adjust the springyness.
