Electric connector plating common problems

Electric connector is a very important electronic component for connection, plating on the connectors is also necessary for protection and anti-corrosion, which can also improve connector durability and wearability.

Below is plating common problems and solutions.

1.       Plating layer roughness;

(1)    Main salt level is high.

Solution is to dilute the plating bath and adjust other composition.

(2)    Temperature is high.

Solution is to lower temperature.

(3)    Cathodic current density is too high.

Solution is to reduce current density.

(4)    Free ammonia is less.

Solution is to add ammonia.

2.       Plating darkens.

(1)    Main salt level is low.

Solution is to add main salt.

(2)    Ammonium chloride is too high.

Solution is to add main salt or raise the temperature.

(3)    Temperature is too low.

Solution is to raise the temperature.

3.       Plating is too fragile and connection performance is not good.

(1)    Cathodic current density is too high.

Solution is to reduce current density.

(2)    Pretreatment is not good.

Solution is to improve pretreatment.

(3)    Cu impurity is too much.

Solution is to recover palladium and use new plating bath.
