Khauta plating e sebelisa molao-motheo oa electrolysis, eo hape a bitsoang electroplating. Tse ling tse ngata tsa dikalafo tšepe holim 'a boela electroplated.
In the actual product application, 90% of the gold pcb board is the immersed gold pcb board,because the poor solderability of the plated circuit board is his fatal flaw, and it is also the direct cause of many companies to give up the gold plating process!
Ho qoelisoa thulaganyou e khauta beha ka holim 'a mapolanka hatisitsoeng oa potoloho le' mala o tsitsitse, khanya e ntle, plating boreleli, le solderability molemo tsa nikele khauta plating.

1. The crystal structure formed by Immersion Gold and Gold Plating is different. Immersion Gold is much thicker than Gold Plating. Immersion Gold will be golden yellow and yellower than Gold Plating (this is the method of distinguishing between gold plating and heavy gold plating.) a) Gold plating will be slightly white (nickel color).
