Thank you Benoit but I need actual data to make a footprint to use in PCB design application.
I think I'm mostly there but was really seeking a better picture so I can confirm the accuracy of the supplied numbers and to which pins they apply - some of the ones buried in the centre of the display are not so clearly linked to the numbers at the side. - Richard On Saturday, 4 November 2023 at 14:37:27 UTC Benoit Tourret wrote: > try to find 0.5 mm inner diameter pipe, 10cm long, fit all the pins, pour > some silicone, you should have a good representation of the socket... if > you didn't forgot to add some wax or similar to unmold the silicon. > the more parallel your pipes will be, the more accurate your print will be. > for a good print, the end of the pins is not important, the most important > is the place they have at the beginning, the nearest to the display. > without sacrifying a display; I don't see any other way to have a good > measurement. > > Le samedi 4 novembre 2023 à 10:04:19 UTC+1, Richard Scales a écrit : > >> Hello, there are indeed a few the line up - it's the ones that don't that >> worry me the most! >> - RIchard >> >> >> On Saturday, 4 November 2023 at 08:54:44 UTC Benoit Tourret wrote: >> >>> Hello Richard, >>> >>> have a look on the SP-351, >>> >>> https://www.tube-tester.com/sites/nixie/data/datasheets/SP-351_SP-352-drawing-01.jpg >>> [image: SP-351_SP-352-drawing-01.jpg] >>> not the same number of digit, but some of the pins should be identical... >>> On my SP-356, there is 0 aligned pins on a diagonal way. only in >>> horizontal. >>> >>> Le samedi 4 novembre 2023 à 07:31:29 UTC+1, Richard Scales a écrit : >>> >>>> I used to so that but it relies on all the pins being straight and for >>>> this particular display - there are 30+ pins in a very small space - the >>>> more accurate the better - especially when it finally comes to plugging >>>> the >>>> things in! >>>> [image: TTPicture.JPG][image: PPpicture.JPG] >>>> >>>> Perhaps the differences are so subtle it's not worth worrying about. >>>> It's like staring at constellations!
