Immersion tin board for Automotive
Application area: Automotive Product feature: Immersion tin board Layer: 4 Surface treatment: Immersion Tin Material: FR4 Line width/Line space: 0.254/0.20mm Thickness: 1.6mm Min hole φ: 0.45mm What is Immersion Tin Plating? Immersion tin is a coating of tin deposited on the copper layer of a PCB using an electroless chemical process . The tin layer protects the board from oxidation, extending its shelf life. It is usually white after electroplating, so it is called white tin. What is Immersion Tin PCB? PCB tinning is the process of covering copper traces with a layer of tin, which will prevent any possible degradation, oxidation or corrosion of them. Tin plating also helps mask copper traces when etching the board itself. Immersion tin pcb surface finish describes a very thin layer of tin applied to the copper layer of the PCB. This method is a lead-free PCB alternative that produces a consistently flat surface that solders well and is cost-effective. The tin layer is us...
