WitrynaIPC‐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 amended in 2011. WitrynaDisplacement reaction between copper and tin leading to a tin deposition on copper substrate is widely used in the printed circuit board technology [3-7]. According to the value of the electrode potential the tin deposition on copper is couldn’t be realized. Addition of some complex agents to the solution allows the reversion to be achieved.
