The choice of PCB surface treatment processes depends on the final assembly components, with five common methods including hot air leveling, organic coating, electroless nickel/immersion gold, immersion silver, and immersion tin, each offering specific advantages and limitations for different applications.
Typical Applications of PCB Surface Treatment Processes Read More »
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.
