PCB FEA: Pogo Pin Stress
Budget: $10 – $30 USD
I need a finite-element simulation to show how my FR4 board behaves when it is pressed simultaneously from the top and bottom by spring-loaded pogo pins. The board is captured in a custom fixture that relies on a mix of hold-down support and tooling pins rather than standard clamps, screws, or snap-fits, so the boundary conditions must reflect that hybrid restraint.
Key physics
• Static analysis that captures contact forces from a randomly distributed array of pogo pins on both sides of the board.
• Output of von Mises stress, principal strain, and any through-thickness deformation so I can judge whether the present support is enough.
What I expect to receive
1. FEA results and model plots
2. Your recommendations for additional supports if margins are low.
I will supply PCB geometry, pin locations, and loading values the moment we start. Let me know which solver you prefer, any assumptions you need clarified, and the turnaround time you can commit to.
