Kita says its AU1000 gold plating process for test probe plungers offers surface hardness of 1,000 on the Vickers scale, significantly harder than traditional plating options.
According to the company, test probe plungers historically have been plated with hard gold (Hv 200) or combinations of gold and/or palladium plating (Hv 400-500). This was adequate because the plunger tips were contacting solder balls (Hv <50) or gold-plated IC pads. With the introduction of nickel-palladium-gold plating (Hv 400) on IC leads and pads however, a harder surface finish is required on the plungers to prevent tip wear and yield loss, Kita says.
