[neonixie-l] Re: Nail Head pins
My application is to make a small circular PCB which will 'plug' in place of a Z566 tube - hence the need for 1mm diameter pins. This small board will then have some interconnecting pins (positioned within the confines of the Z566 pin positions) that reach up to a similar small board which has matching positions for the interconnecting pins. The top board will have pin sockets (Harwin style) for an IN-18 tube. The track layout takes care of all the required pin mapping. The boards will be spaced sufficiently far enough apart to avoid any electrical contact between them other than that provided by the interconnecting pins. For the board interconnects I plan to use pins clipped from a strip of 0.1" spaced header pins - the commonly available type - there are no special requirements of these pins apart from being long enough! Ultimately - the completed item will allow an IN-18 to be used in a socket designed for a Z566. A variant of this would allow a Z566 to be plugged in on the top board so that IN-18 and Z566 could be intermixed and presented at the same height. This is something that I was asked to make for a colleague who wants to showcase different tubes on the same clocks - no other aesthetic justification (positive or negative) required! - Richard On Saturday, 12 March 2022 at 02:21:28 UTC nei...@gmail.com wrote: > Richard, I have quite a bit of experience with these in a number of > different applications.

Richard, I have quite a bit of experience with these in a number of different applications. On the off chance you haven't discovered this, here are links to the two biggest manufacturers: Mill-Max (obviously you've found them) https://www.mill-max.com/products/new/pcb-sockets-and-micro-plugs TE Connectivity (legacy AMP) https://www.te.com/usa-en/plp/Y30gv.html About Chinese suppliers . . . generally the quality is good but the number of sizes and styles offered is extremely limited. Basically they "cherry pick" their offerings to high market volume/demand versions. It would help to know details about your desired application or more specific question(s). Neil Q.

Very nice looking adapters though. I am looking at some pins that have a slight shoulder which will (hopefully) mitigate against them being pushed through the board. - Richard On Thursday, 10 March 2022 at 12:11:57 UTC Dekatron42 wrote: > I haven't used that exact type of pins but I tried a similar type and had > some problems with them when they were subjected to pressure from the side > which resulted in them coming loose.

I haven't used that exact type of pins but I tried a similar type and had some problems with them when they were subjected to pressure from the side which resulted in them coming loose. I had to minimize the hole diameter in the circuit board almost to a press-fit size so they couldn't flex/bend but then I also got some problems with a few that were pushed up when inserted as I guess that there was to little solder fastening them - a proper press-fit pin would have been better for my case but I didn't find any that fit my needs. It could probably have been done better but I didn't have the space nor the time to experiment much more so I decided to go with longer pins and two circuit boards on top of each other. I ended up buying cheap gilded longer pins without the head from eBay (Chinese seller), similar to the ones used in the adapter below.
