Conformal Coat Underfill on HD connectors | 9 September, 2004

Does anyone have any experience with underfill of HD connectors? New customer wishes to underfill 6 HD connectors that have been pressed into PCB. Capillary action is causing the conformal coat to wick up into connector. Material is acrylic.

Check with your connector supplier, but most press-fit contacts will pierce through Types UR & XY conformal coat (military approved).

Acrylic (AR) Urethane (UR) Epoxy (ER) Silicone (SR) Parylene (XY)
