Hello Technetters. Is there an IPC specification which gives the quality levels of workshops (temperature, humidity, cleanliness) according to the quality of the assemblies? For example, assemblies IPC class 3 must be necessarily assembled in clean rooms or just with control of humidity and temperature?
