Immersion tin pcb

WitrynaThe trade Association Connecting Electronic Industries, IPC, defines Immersion Tin (ISn) as a metallic finish that manufacturers apply directly over the basic metal of the circuit board using a chemical displacement reaction. The main functionality of ISn is to protect the underlying copper surface from oxidation. WitrynaImmersion Silver Similar to tin, this PCB finish is used in high-speed signals that don’t contain any nickel. Immersion silver, however, does require unique storage as it will tarnish if exposed to air. Advantages: Nickel-free Faster signal speed than tin RoHS compliant and environmentally friendly Disadvantages: Becomes contaminated easily
