Typical Applications for 2 Layer Immersion Gold PCB

2 layer immersion gold PCB” refers to a printed circuit board with a two-layer design and immersion gold surface treatment. The surface of an immersion gold PCB facilitates the precise placement of components. This ensures that members adhere well to the gold layer, maintaining stability and minimizing the risk of damage during assembly or handling. Today we will introduce to you their main applications.

What are the advantages of 2 layer immersion gold PCB?

An “Immersion Gold” finish involves applying a thin layer of gold to a bare copper surface through a chemical deposition process. This immersed gold layer enhances the performance and reliability of the PCB. Advantages of 2-layer immersion gold PCBs include improved solderability, corrosion resistance, and a flat surface for component mounting. The gold layer prevents oxidation of the copper pads, ensuring clean and reliable solder joints. This is especially important for fine-pitch components or components that require precision soldering. The gold layer also protects the copper traces from corrosion. This increases PCB life and reliability. Let’s take a look at what applications they are suitable for.

Application of 2 layer immersion gold PCB in electronic products

Among various electronic products, 2 layer immersion gold PCB is usually used in lighting systems and control boards of different electronic products. Its two-layer design provides a cost-effective solution for simpler circuits while ensuring reliable interconnection between components. They can improve the overall reliability of electronic equipment. In particular, their immersion gold surface treatment enhances solderability and prevents oxidation of the copper pads during solder assembly. The immersion gold layer’s corrosion resistance is particularly beneficial for these electronic devices exposed to environmental conditions.
