'Known good' SOIC Clip
I've designed this connector into a PCB, I think it's quite a neat solution - thank you for designing it.
Unfortunately the SOIC clip I used was a bit flimsy, and so never made very good contact with the PCB, and before long the plastic guide pins broke.
I was wondering therefore if you had the model number of a SOIC clip that was easy to modify, and worked reliably?
@joshtyler I'm afraid I have just been lucky with the cheapest of the cheap from eBay/Aliexpress etc. Let's keep this issue open for a while and see if anyone else has any tips for clips they'd recommend as it would be good to have one people could rely on a bit more.
I have been using this one https://smile.amazon.com/gp/product/B015W4PKR6. Requires modifying as normal but clips fairly strongly. You can remove the center pin and stretch the spring a bit for an even strong clip
Have you thought about designing something for 3D printing? Would mostly require an equivalent spring and contacts (maybe it could be designed for standard pin headers, after removing their plastic housing). This way the teeth could be made to grab the PCB before the pads are contacted
The cheap black soic8 clamps seem to use weak plastic, so they can be used ten to twenty times but then their spring will crush the guides. I got mine for $0.70, so next time I need them, I'll invest in these more rigid looking test clips, I haven't tried them yet though.

Interesting - I haven't experienced this but not done many tens of use cycles. Please do update us with what you find when you get the other clips.

No but open to suggestions. There are quite a few decent clothes-peg type custom clips out there, often built from PCB/Acrylic and pogo pins.
