Soldering the contacts directely in the PCB makes a quite stressfull connection for tubes with a high number of pins, because of designe tolerances. Therefore tube sockets for tubes with glass sealed pin feed-throughs alsways have loosly mounted socket contacts. That's just what Dekatron42 describes. eric _____

I intend to see how many pins are needed to support the weight of the tube, so that will give me an idea of the retention force. * Midsection, about 1.6mm diameter. I was planning to solder this into the PCB. I just need to be very careful no solder wicks into the region that contacts the tube-pin. * Tail-end, approximately 0.5mm diameter. I was planning to snip this off after soldering. I've thought about having a friend 3D-print a shell to hold the pins, but it's probably overkill. Everything below the tube base, including the PCB, will be hidden inside the case. Fortunately this clock will sit on a shelf, and never moved, so it's not necessary for the nixies to be tightly gripped. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
