Weblowing IPC standard: The IPC-A-610 Rev. G, Acceptability of Electronic Assemblies, which illustrates the requirements for many types of solder connections. Classification Through-Hole solder joint requirements are divided into three classes depending on the ultimate use, life expectancy and operating environment of the electronic assembly. WebIf we take a Start Copper of 70 µm it must have a minimum End Copper of 78.7µm under the IPC-A-600J-Class 2 Standards. Here we state +/-95 µm as “ Our Nominal End Copper Thickness ” again based on our manufacturing experience. The “+/-” again means approximately but has a guaranteed minimum thickness of 78.7 µm. howbeck road nottingham
