Gold Plating for Probes

26 April 22

The probe plunger materials are mainly beryllium copper, SK4, brass, etc.

The plunger of the probe is usually plated with gold to prevent the copper from rusting, because the patina produced after rusting will increase the resistance, and the stability and function of the probe will also be affected.

Gold plating enables low contact resistance, good electrical conductivity, easy soldering, strong corrosion resistance, and makes the plunger has a certain wear resistance.
