What is the latest on low stress sockets?
3D printer ones coming along?
 
I am keen to hear from you all about the latest successes.
 
Anyone contemplating a ZIF style  - either rotate or slide locking etc?

Would be nice, I finally should be able to test my EZ10A tubes.

Otherwise, does a printed socket withstanding 15 soldering actions without troubles? I would rely more on CNC milling….

I do mine in 2-steps:
  • Low-insertion socket pins soldered to PC bpard
  • 3D-printed collar that sets over the pins. It's mostly for aesthetic reasons, because the pins dont fit snugly into the collar. The collar certainly helps guide the tube into the socket. However, you should avoid plugging/unplugging unless necessary.

It’s not the insertion of the tube that worries me, but the long term stress due to slight misalignment of the bushings. That concerns particular hydrogen and helium filled tubes. Keep in mind tubes like EZ10A and B have a very dense 13 pin socket that needs narrow tolerances in alignment. It’s therefore not wise to use PCB-sockets, a floating wiring is better.
