Home-Splash_SMTAutomatic or automated optical inspection is an important technique used in the manufacture and testing of PCBs. This advanced technology enables quick and accurate inspection of electronic assemblies for specific PCBs to ensure that the final product achieves high quality standards and complies with the customer’s requirements

With the constant evolution of technology, manufacturers have been able to design and build automated optical inspection (AOI) systems that detect faults and respond faster to ensure speedy correction, ultimately resulting in an error-free production line. Since high volumes of quality products need to be manufactured quickly today, reliable and fast inspection methods are needed to ensure that product quality remains consistent..


CyberOpticsModel: SQ3000, Brand: CyberOptics, Manufacturer: CyberOptics Pte Ltd, Singapore

The SQ3000 is powered by CyberOptics’ breakthrough 3D sensing technology comprising four multi-view 3D sensors and a parallel projector delivering high-grade accuracy at production speeds. SQ3000 offers the revolutionary MRS technology by precisely identifying and rejecting reflections caused by shiny components and reflective solder joints. AI² (autonomous image interpretation) technology keeps it simple with no parameters to adjust or algorithms to tune. The CyberReport offers full-fledged machine-to-factory SPC capability, with powerful historical analysis and reporting tools delivering complete traceability for process verification and yield improvement.
