In most SMT lines, a high percentage of the error alerts generated by AOI optical inspection equipment machines are false calls. As a result, anywhere from 30% to 80% of the PCBs that AOI machines report as failed are later judged to have passed once they are reviewed by an operator. Checking every single unit failed by the AOI machine requires a huge amount of manual work and time, significantly reducing line productivity.

The Valor AOI Machine False-Call Reduction Predictive Analytics Solution uses artificial intelligence to predict with high accuracy whether a failed board is a false call or a real error. It reduces the number of false calls from AOI machines, and thus reduces the manual review work associated with them.

Depending on the value of data that is collected from your AOI SMT machine, the Valor AOI Machine False-Call Reduction Solution can eliminate up to 60% of manual work at the visual inspection phase, driving high throughput and supporting zero-defect production.

Any AOI machine is supported, and the solution is suitable also for high-mix production environments. 

The Valor AOI Machine False-Call Reduction Solution is available as an annual subscription. Contact your local representative for pricing information.
