PCB Surface Finish Possibilities Pros & Cons
PCB Surface finish form the interface that is critical the board and the elements. In recent years, their availability that is widespread has some electronic designers. This post hopes to shed some light in the pros and cons for the four most principal PCB area finish solutions available on the market: Organic Solderability Preservative (OSP), Electrolysis Nickel Immersion Gold (ENIG), Electroplated Nickel Gold and Immersion Tin or Silver. The after post pertains to Rigid Printed Circuits Boards (PCB) and Flexible Printed Circuit (FPC).
Note: PCBs are often manufactured from rigid materials and can maybe not bend during their application. FPCs are thin making of materials with the capacity of bending movement that is and/or application. Processing and application demands dictate whether or not the PCB surface finish is electroplated, electrolysis, immersion or deposited.
Conditions that influence PCB Surface Finish Selection:
Oxidation protection of …
