We are currently in the process of creating Hardware-Test-Boards where we want to "plug-in" our PCB's and do a couple of tests. Our Boards have a rather complicated shape and are mostly surface mounted. Thus we have a hard and error-prone time to figure out, how to automate our tests due to connectivity issues.

Recently I found something on the Omega2s that would perfectly fit our needs.

enter image description here

The HDK of the Omega2s features those nifty little springs to plug in the sourface-mounted Omega2s which are holding it snug in place. But we are unable to find those Springs on e.g. Mouser and Digikey.

How are they called? Where do I find some?

(We already have a footprint, just one hole and a long-hole).

  • I bet onion.io could tell you, and let you know about any special requirements, if any, at the same time. – Andrew Morton Nov 15 '18 at 10:40

    @AndrewMorton we already contacted onion.io but they only tell us generic stuff that an engineer will contact us, "soon". A BOM is also not available. At least we found none. – bam Nov 15 '18 at 11:28

    Those are "spring contacts". I don't know where to buy exactly these, but you can buy them similar things as battery connectors for e.g. the old exchangeable lithium batteries in pre-smart-era phones. – Marcus Müller Nov 15 '18 at 11:40

    Do a search for "Pogo Pins" – EE_socal Nov 15 '18 at 17:02
  • [Tag-Connect](http://www.tag-connect.com/EdgeConnectIntro) sells something similar. – Jeroen3 Jan 04 '19 at 22:54
  • That looks like a custom spring, and would have to be hand-assembled. For mass production, elastomer one-dimensional conducting strips, so-called Zebra strips, are often used. – Whit3rd Jan 05 '19 at 07:37

Mill-Max (mill-max.com) makes a huge variety of spring-loaded contacts, some forms of which are commonly known as "pogo pins". They come in a variety of shapes, sizes, spring travel, and (most important) shape of the contact end of the pin. Digikey carries a lot of them.

You'll also need some kind of jig to hold the part under test firmly against the contacts, but presumably you already know this.

    Those are **not** pogo pins. The question is about the wire looking things around the hole in the pictured PCB. – JRE Jan 04 '19 at 22:40
