The Meaning of "Verified"

Finding a schematic is easy; finding a verified schematic is hard.

A standard schematic is a map of how a device was supposed to be built. A verified schematic is a map of how it actually exists.

When an engineer stamps "LAE791P REV 20" as verified, it means:

  1. Reality Check: They have physically held the PCB up to the light, comparing the silk screen to the paper. They confirmed that the capacitor on the diagram is actually a capacitor on the board, and not a last-minute jumper wire added by a factory technician in 1985.
  2. Error Correction: Manuals lie. Datasheets drift. A verified diagram has been scrubbed clean of the typos and "oops" moments that plague technical documentation.
  3. Continuity: It means someone, somewhere, has taken the time to ensure that this specific piece of history can be repaired again. It has been saved from the scrap heap.
