Consists of a non-destructive optical inspection. Binoculars with magnification between 1x and 60x and with a relatively large and accessible field of view are employed for this purpose.
The aim of this process is to verify the conformity of the exterior of electrical, electronic and electromechanical components (EEE parts) with the acquisition document.
