Koh Young Technology introduces its Zenith 3D AOI System, the new Zenith 3D AOI System measures the Z-axis profilometry of whole PCB assemblies, including components, leads, and solder joints, based on the patented multi-frequency Moiré technology. Zenith is the only AOI system available that’s measurement-based, and gives the user the ability to confirm - without any ambiguity - that their products meet IPC acceptability standards, i.e., IPC-A-610. Zenith’s eight-way light projection and z-axis measurement provide true profilometry, eliminating false calls and escapes. Zenith identifies and flags all defects, and even features enhanced PCB warpage compensation.
 
Measurement-based inspection means that no ‘golden board’ is needed; results are compared directly to the IPC-A-610 Reference. Zenith’s EasyUse Operator interface with Touch Screen, coupled with a short programming time (no fine tuning needed) enhance the system’s user-friendliness and power.
 
“The inability to measure the height of objects makes detection of defects such as lifted leads and components difficult in traditional 2D AOI” Dr. Kwangill Koh, President and CEO, states.
 

 “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. Thus, there is no longer any ambiguity regarding the acceptability of the solder joint.”
