Hi Everyone, Could someone please tell me - What happens if a N-type connector having chromate coating over silver plating is hand soldering to a PCB. Does the Chromate coating form a compound with silver, Or does it come off while cleaning excess

We're unaware of any such reaction. The RoHS Directive bans the use of six hazardous materials. The materials are four metals: lead, cadmium, hexavalent chromium, and mercury; and two brominated flame retardants: polybrominated biphenyls (PBB) and p

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)

Hopefully the coating does contain a UV tracer. We used a silicone years ago that did not, but UV did make it fluoresce to a degree, you just couldn't ensure 100% coverage. One time we did have a problem with the coating getting on connector pins,

Hi Guys, I have few question would like to ask regarding pcb conformal coating: 1. Can I know which masking material is the best for easy apply, fast cure, fast & easy to remove after coating & baking. And no chemical reaction which will whiten the

Hi I am looking for some type of peelable mask or plug to cover the connector during the conformal coating. The problem we have is the moisture get into system and eventually penetrate under the connector creating short circuit to the board. What I r
