IMMERSION GOLD PCB / GOLD PLATING PCB / GOLD PLATED PCB

Immersion nickel / gold is a thick layer of nickel-gold alloy with good electrical properties and can protect the PCB for a long time. Unlike OSP PCB Board, which is only used as a rust-proof barrier layer, it can be useful and achieve good electrical properties during long-term use of the PCB. In addition, it also has environmental tolerance not available in other surface treatment processes.

Features of Immersion Gold PCB

Immersion Gold PCB

The immersion gold board is a pcb board produced by the immersion gold process.

Such immersion gold boards are mostly multilayer PCB boards. The immersion gold process is to deposit a stable color on the surface of the printed circuit, good brightness, flat plating, and good solderability Nickel-gold plating, PCB can be used for a long time without oxidation problems.

Immersion Gold PCB

It is mainly used on boards that have functional requirements for connection and long storage periods, such as the keypad area of a mobile phone, the edge connection area of a router housing, and the electrical contact area of a chip processor's elastic connection. Currently about 10% -20% of PCBs use the immersion nickel / gold process.

Immersion Gold PCB

The general process is: de-acid cleaning-> micro-etching-> pre-immersion-> activation-> chemical nickel plating-> chemical immersion gold; there are 6 chemical tanks in the process, involving nearly a hundred Chemicals, the process is more complicated.
