#Building Test Jigs The rest of this page is a collection of random notes on building test jigs. Mostly it's a record of mistakes to be avoided.

Making the pogo board

• Design and manufacture tester PCB from 0.93" FR4
  • Use socketed pogo pins (exclusively). IDI on Mouser. Expensive but worth it
  • Use 4/40 hw for standoffs - 0.125 ID holes, 0.250" clearance
  • Pogo holes 0.063" (see below)
• Laser cut a spacer plate of 1/16" clear plexi to line up the pogo sockets
• Use IDI Size 3 preferentially - 0.125" centers
  • Tester board holes 0.063"
  • Spacer plate holes 0.095"
  • Parts
    • R-3-SC receptacles (sockets)
    • S-3-H-4-G waffle head
    • S-3-A-4-G cup head
    • S-3-B-7-G spear
• Use 0.100" only for those things that require tighter spacing
  • Tester board holes 0.063"
  • Spacer plate holes 0.067"
  • Parts
    • R-100-SC receptacles (sockets)
    • S-100-WO-8-G-S crown head
    • S-100-A-6.7-G cup head
    • S-100-J-6.7-G headless radius
    • S-100-B-6.7-G headless spear
    • S-100-AP-6.7-G-S headless sharp chisel
• Assemble all electronics first before attaching pogo pins
  • e.g. regulators, connectors...
• Attaching pogo receptacles to tester board
  • Insert receptacles into all holes to be filled
  • Position spacer plate roughly over holes
  • Insert pogos through plate to line up pogo receptacles with spacer plate holes
  • Carefully work the plate onto the pogos
    • Stop at the annular detent ring
    • Push too hard and will crack the plate
  • Before soldering - ensure first pogo is at right angle to the board!!! Very important!!!
  • Solder it and do another pogo at the far end, also at a right angle
  • Solder only on the side with the trace to make removal easier (if you eventually need it)
  • Do not flex the sockets. They will break off at the collar
