Surface treatments for printed circuit boards (PCBs) encompass various methods like gold plating, tin spraying, immersion gold, immersion silver, and OSP. These treatments cater to different needs, offering advantages such as oxidation resistance, good solderability, and environmental friendliness. Gold plating, though costly, remains vital for high-performance connectors, while tin plating predominates due to lower costs, especially in mainstream electronics like motherboards and memory modules. Immersion gold boards mitigate issues like the tin whisker effect, providing superior solderability and flatness, making them increasingly preferred in modern PCB applications.
The evolution of PCB surface treatment technology, influenced by environmental concerns and evolving industry standards, emphasizes lead-free and halogen-free processes like organic coating and electroless nickel plating/immersion gold, while also considering factors like component type and assembly requirements, leading to a dynamic landscape of options with a focus on meeting customer needs and environmental standards.
Various surface treatment options are available in PCB production, each differing in price and process; today, we focus on OSP treatment. OSP PCBs require careful handling, storage, and solder paste application to maintain quality and longevity.
Selecting surface treatment processes for 5G base station high-frequency circuit boards is crucial; while bare copper boards perform well, opting for processes like immersion silver, immersion tin, or nickel plating/immersion gold ensures optimal solderability, electrical performance, and resistance to environmental factors.

The electroless nickel/immersion gold process provides a thick protective layer for PCBs, enhancing electrical properties and offering environmental tolerance. Immersion silver falls between organic coating and electroless nickel/immersion gold in complexity, providing good electrical performance. Immersion tin shows promise but faces issues such as tin whisker formation and migration. Other widely used surface treatment processes include nickel-gold electroplating and electroless palladium plating for enhanced welding reliability and surface smoothness.
