ABSTRACT:
The method of assembling a CRT includes (1) providing at least one envelope part having a unique, optically machine-readable, process-survivable coded marking on an external surface thereof, (2) optically machine-reading the marking, (3) generating a signal in response to step (2), (4) in response to the signal, initiating a local process for action with respect to the envelope part and (5) recording data of the local process with reference to said coded marking. The action may include transportation of the part, assembly of other parts or subassemblies to the part, or testing of an assembly including the part.
