  • AEC-Q components go through a LOT of testing.

  • Do not use passives larger than 1206 without simulation - they can crack under pressure.

  • tablet should be able to be replaced easily in case things go wrong.

  • diode should cause a short, which blows the fuse and protects the load.

  • connectors should have latches. Or use glue (UV cured)...

  • terminal position assurance (TPA) can be used to keep terminals in (molex product spotlight pic)

  • current should go THROUGH cap

  • avoid header terminals (basically anything used for arduino/raspi projects). They are not well suited for resisting vibration.

  • thermal fuses are probably not the best considering the environment we live in...

  • E-fuses are recommended (Tesla uses them)
