VVS, which stands for Virtual Verification System, enables PCB manufacturers to significantly improve AOI cycle efficiency by reducing the number of verification stations and their associated manpower.

How does VVS work?

VVS consists of a server that pulls the images of defects from every CIMS AOI and then sends them to VVS stations for sorting and filtering. In VVS stations, those images are shown to operators who then quickly remove non-critical and non-functional calls while passing only images that are most likely to represent true defects directly to CIMS Verification & Repair stations (CVR).

As a result, subsequent visual verification of actual panels with CIMS CVR focuses mostly on marking and repairing of the real defects rather than skipping over non-critical and non-functional defects.

Moreover, VVS operation enables defects classification that is normally done on CVR. This further simplifies the visual verification process.
