English copy

Audio contact reliability depends on more than appearance. Base material, plating system, contact force, alignment, contamination, wear, and strain relief all influence signal continuity.

Plating should be selected according to mating frequency, environmental exposure, required service life, and cost target. The supplier should be able to identify the base material, plating material, thickness range, and inspection method for the approved model.

A useful validation plan includes contact resistance, insertion and withdrawal force, repeated mating, corrosion or environmental exposure where relevant, cable pull, and signal continuity after testing.

FAQ

Question	Answer
Is thicker plating always better?	Not necessarily. The plating system and application conditions matter together.
What causes intermittent audio?	Contact contamination, wear, insufficient force, misalignment, cable damage, and poor soldering can contribute.
Can plating options be customized?	Material and plating options can be reviewed for the required mating and environment.
