The glue should have 2 functions
  • Reinforcement of the connectors when being manipulated for plugging/unplugging or mechanical mouvements
  • Insulation of some accessible pins

Applications

  • Samtec connectors
    • At the base of the connectors on the inner side → Reinforcement
    • On the pins sticking out on the outer side → Insulation
  • Grove connectors → At the base of the connectors on the inner side → Reinforcement
    • Contact Plate
    • BMS
    • I/O
  • XT Connectors → On the pins sticking out on the outer side → Insulation
    • Contact Plate
    • BMS
