Title: Logic Analyzer probes for SMD
Post by: obiwanjacobi on March 18, 2015, 09:45:49 am
I am looking for a (the easiest) way to attach multiple logic analyzer probes (inputs) to a(ny) smd PCB that is under test/repair.

I know of the bed of nails technique/idea, but the boards are different every time and as exploration of the PCB/schematic advances so will the test points I require to measure. So I need something that is really flexible.

I thought of using the individual bed-of-nails pins but what would be a good way to fix them into position? 3rd hand alligator clips are to flimsy and do not keep my (normal) probes in place...

I cannot hold the by hand because I need those to trigger test scenarios and work the computer...

Any ideas are most welcome.
Marc

There was a guy who had a kickstarter here for brackets and pins for soldering that I would think could also be used for this task.

I've got the XKM grabbers that came with my Saleae unit that are pretty small but then again so are smd pins.  You can get them on eBay for a pretty good price if you search a bit.

Search for hp agilent 5090-4356 on ebay there are a lot of 20 packs.

Good luck!
