SAS testing environment is based on Aleader AOI i3D Automatic machine.
Aleader machine covers all defect ranges including all kinds of lifted leads and all defects on small chips, as well as all coplanarity defects.
Continuing miniaturization of components and increasing complexity of boards is driving the need for PCB AOI Testing:
PCB Parts inspection is a computerized function that compares the image of a PCB captured by a CCD camera with the image of a good PCB memorized in advance, and determines whether it passes inspection or not.
This determination is performed at high speed by the specification of the portion to be inspected, the inspection of the existence of parts, positional divergence of parts, wrong parts, etc. As color factors are also inspected, objects which cannot be discriminated between good and defective by brightness alone can still be judged reliably.
PCB Solder print inspection is a function that inspects the status of a solder printed surface by examining its area, place and form. Data processing is carried out in natural light, as in the previous parts inspection. Moreover, no special hardware is required.
The reference data for the solder printed surface to be inspected may be GERBER data, automatic sampling, or a manual designation.
