Immersion Silver
Immersion Silver describes a Lead-Free layer of silver plated onto a PCB, to protect copper traces from corrosion. Silver surface finishes have excellent solderability, comparable to solder plating, accommodating a straightforward and risk-free PCB Assembly Process. Immersion Silver also boasts a moderately long shelf life, though still less than some of the other finishes, such as ENIG. Immersion Silver is a popular choice due to the fact that silver is the most electrically conductive metal available, and thus ideal for High-Speed PCB applications. Silver surface finishes can be applied to copper traces with an electroless immersion reaction, displacing the copper layer.
The application process for this surface finish forms a very flat surface, which is advantageous for SMD Assembly, allowing for Bittele to streamline your Complete PCB Assembly project, and make sure your overall turn time is as low as possible. Silver immersion is a surface finish with benefits that far outweigh its costs, and thus it has gained widespread popularity since the RoHS and WEEE directives came into effect; however, Silver Immersion is not without its drawbacks. Silver is sensitive to contaminants, both in the air and on the board, and thus it must be packaged as soon as possible to prevent tarnishing.
