Where to buy tiny test clips?

Started by Klaus Kragelund October 17, 2021
Hi

For testing on prototype with small SMD components I normally clip off a leaded pin and solder it on the component

I need very small clips to attach with small diameter wire to have very little mechanical stress on the components

Anyone got a good reference?

(sometimes I use enameled copper wire, but it takes longer to set up) 

Regards

I could buy this, but 11 USD for a clip seems a bit high: https://www.digikey.com/en/products/detail/cal-test-electronics/CT2592-2/5028700 -- Klaus

Logic analyser test probes? Cheap as chips on eBay. -- Cheers Clive

Wire wrap wire.

I can get cheap ones from China, but unsure about the quality I recently bought some BNC to banana plugs, and the quality is horrible -- Klaus

Years ago I picked up some TP grabbers from digikey. The were $35 for 10p s. Now they are 10 bucks each. They are good for soic size stuff. Now I am looking for ridged arms that can hold my singer sewing needles in place. Sort of what Pico offers. The micro grabbers are too big for the smaller pitch devices. I tend to add pads for probing to work around the fine pitch probing issue. Cheers -- ----Android NewsGroup Reader---- https://piaohong.s3-us-west-2.amazonaws.com/usenet/index.html

I normally strip #26 tinned stranded wire and use the individual strands.
