Locating a specific standoff for PCB

[tharptroy]

I realize that this is a long shot, but does anyone know where I might find the supplier that makes these?

I realize that the circuit board manufacturer has some sort of automated machinery to insert and flare these, and we would be looking to have something similar for our (non-circuit board) application.

any help/ideas or even another place to look would be awesome.

google search has failed me on this. (or I have failed, not sure which)

Never seen one that is "swaged" on both sides but we use Lyntron for all our swage standoffs/swage spacers. And they give the best pricing we have found if you need a custom one too.
Not really sure what the purpose of the swage on the non-pcb side is though.. A regular swaged standoff "should" work too.

Looks to be flared for easier insertion of a screw, and so it won't slip into a hole with screw clearance.

There have been many a board stack I've assembled for which this would have been really slick...

I'd guess it might just be cheaper for the manufacturer of that standoff to use smaller round stock and swage to keep it from slipping in a hole versus just using the next size up of round stock.
Unless there is some other purpose of that double swage a regular swage standoff "should" work just fine.

Thanks for the suggestion, I will contact Lyntron about a custom piece for us.

The secondary flare is absolutely necessary for my application (not being used as a PCB standoff).

This was from a generic ignitor module for a furnace. I guess the flare could provide better stability, and it certainly allows for a much greater tolerance when screwing it in.

I've never seen one like that for a PCB. But, it's basically a custom eyelet. If you need something identical, check with Stimpson Eyelet - they've got millions of different varieties. Not all are shown in their catalog, and they do customs as well.

Otherwise, if your volumes are not extremely high, I would use a swage spacer - these are made by using a screw-machine instead of a deep drawn sheet metal press. As suggested by others, Lyntron is a good source (and their swage tools dies are excellent). Keystone also makes swage spacers, both threaded and clearance. Most Keystone is stock at Mouser. Lyntron's quality is higher, but Keystone is more available in low volume. I frequently use Keystone for prototypes, and Lyntron for production.

You guys were right, it is in fact, an eyelet! Thanks for the tip.

Unfortunately, the size that I need (not pictured) is not a standard part. Stimpson has also told me that they cannot manufacture a part with the length/diameter ratio that I have requested, since these are drawn parts.

I guess I need to look into having these made on a screw machine.

Thanks again guys!

I still see no real/good reason that a standard swage standoff cannot be used. But that's up to your engineering judgement not mine.
