AURUNA® 5000 Fine Gold Electrolyte

AURUNA® 5000 coatings have a fineness of over 99.95% and a hardness of 70 – 85 HV 0.025, which means they comply with the ASTM B488 – 01 Type III Code A/B classification.

The printed circuit boards are plated in a matt nickel bath before gold plating, pre-gold plated and then coated with AURUNA® 5000. The result is gold layers with excellent bondability and solderability, high ductility and low electrical resistance.
