The A.O.I. test verifies the finished conductor trace image for deviations PCB from the Gerber data and finds errors that the E-Test may not discover, such as (for example) narrowed, but still unbroken conductor traces PCB. The A.O.I. test is especially important for the following application areas PCB: High frequency High power loads High data transmission rates PCB Op-amps PCB with high amplification factors and input resistances The inner layers of multilayer boards are checked using A.O.I. before they are pressed together. PCB This guarantees the high reliability of Multi PCB multilayer circuit boards.
