WebIPC‐4554 Immersion Tin (2007) The immersion tin thickness will be: 1.0 µm (40µ”) minimum at ‐4σ from process mean as measured on a pad of area 2.25²µm (3600² mils). Typical value of 1.15µm ( (46µ”) to 1.3µm (52µ”). The immersion tin Specification IPC‐4554 was … WebIPC-4554, a full color document, is intended for use by supplier, manufacturer, contract manufacturer (CM) and original equipment manufacturer (OEM). The immersion tin (ISn) is a metallic finish deposited by a chemical displacement reaction that is applied directly over the basis metal of the PCB, that is, copper.
