The A.O.I. test verifies the finished conductor trace image for deviations from the Gerber data and finds errors that the E-Test may not discover, such as (for example) narrowed, but still unbroken conductor traces.
The A.O.I. test is especially important for the following application areas:
- High frequency
- High power loads
- High data transmission rates
- Op-amps with high amplification factors and input resistances
The inner layers of multilayer boards are checked using A.O.I. before they are pressed together. This guarantees the high reliability of Multi-CB multilayer circuit boards.
Your advantage with Multi CB is that A.O.I. is always included for multilayer boards!
On request, 1 and 2 layer circuit boards can also be tested with A.O.I.
