This message is pointed to those of you involved in RF circuitry I think. 

The IPC-6012 specification for trace with tolerance of ±20% is coming under
fire here. Typically what can most PCB fabricators hold for trace width
tolerance regardless of what IPC says. How do other RF designers specify
trace width tolerances in critical circuits.
