Kwamitin PCB electro-gold obtains gold through electrolysis, while chemical gold obtains gold through chemical reduction reaction!

Simply put, PCB electroplating gold, like other PCB electroplating, requires power and a rectifier. There are many kinds of processes, including cyanide-containing, non-cyanide systems, and non-cyanide systems, such as citric acid type and sulfite type. All non-cyanide systems are used in the PCB industry.

Sinadarin zinare (electroless gold plating) baya buƙatar samun kuzari, yana sanya zinari akan allo ta hanyar sinadarai a cikin maganin.
