A.O.I. - Automated Optical Inspection

PCB AOI

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.
