Immersion tin 불량
WitrynaImmersion Tin. According to IPC, the Association Connecting Electronics Industry, Immersion Tin (ISn) is a metallic finish deposited by a chemical displacement reaction that is applied directly over the basis metal of the circuit board, that is, copper. The ISn protects the underlying copper from oxidation over its intended shelf life. WitrynaPoniżej przedstawiamy krótkie zestawienie najczęściej stosowanych wykończeń powierzchni.

WitrynaAn immersion tin plating solution is a re-usable solution that deposits tin onto copper traces on a circuit board. Professionals call this process immersion tin plating and reserve the term electroless for something else. The solution can plate 1.0 to 1.5 microns, depending on the size of the part to undergo plating.
