Zenith 3D AOI system offers measurement-based inspection

Koh Young Technologies recently introduced the Zenith 3D AOI System. The new automated optical inspection (AOI) system measures the Z-axis profilometry of whole PCB assemblies, including components, leads, and solder joints, based on the patented multi-frequency Moir technology.

Koh Young says that Zenith is the only measurement-based AOI system available. It enables users to confirm that their products conform to IPC acceptability standards (i.e., IPC-A-610). Zenith's eight-way light projection and z-axis measurement yields true profilometry, eliminating false calls and escapes. Zenith distinguishes and flags all defects, and even offers enhanced PCB warpage compensation.

Measurement-based inspection means that no 'golden board' is required; outputs are compared directly to the IPC-A-610 Reference. Zenith's EasyUse Operator interface with Touch Screen, combined with a short programming time (no fine-tuning needed) significantly improves the system's user-friendliness and power.

Koh Young Technologies President and CEO, Dr. Kwangill Koh says, "The inability to measure the height of objects makes detection of defects such as lifted leads and components difficult in traditional 2D AOI. True 3D AOI provides the ability to measure the height and shape of components and even shiny solder joints, and allows a true comparison with the IPC-A-610 standard for inspection." He adds, "Thus, there is no longer any ambiguity regarding the acceptability of the solder joint."
