During the inspection process, a tall component will naturally cast a shadow over nearby component placements, which has historically been a signifcant challenge for accurate inspection of the shorter components. Yet, the Zenith S, like other machines in the lineup, includes an option for 3D inspection of components up to 25mm tall. The Zenith S overcomes component shadow challenges by incorporating multi-projection moiré interferometry system.

Combining innovative vision algorithms and advanced optical inspection technologies, Koh Young delivers highly-reliable inspection of through-hole and selective solder joints.

With the Zenith series, inspection capabilities extend beyond components and solder joints. By combining 2D and True 3D technologies, the AOIs identify foreign object debris (FOD) across the whole board. WFMI technology provides solutions for dropped components, solder balls, dust, debris, and burrs, as well as copper exposure, markings, and more. By identifying these issues, the Zenith can help reduce feld failures.

The Zenith S system is a versatile inspection solution that is adaptable to many application scenarios, including pre-refow, selective soldering, and post-refow inspection. With a high degree of functionality, it can be confgured as an ofine Inspection-Verifcation-Repair work cell for an operator to perform all three functions efciently. Since the program is compatible with our inline systems, the Zenith S can be used for
ofine program generation to maximize the SMT line for production.

The Zenith S system handles large PCB panel sizes up to 650 x 600mm (25.6×23.6”). With the open board loading area and reciprocating shuttle, board loading is simple, easy, and efcient. Additionally, this system can be confgured with a third-party robot board handler or multi-axis robot to further simplify panel loading and unloading.

The Zenith S system is fully compatible with other Koh Young inline True 3D AOI systems. Manufacturers using the inline and standalone AOI systems like the Zenith S can prepare the job program on either
machine. Additionally, operation and maintenance training is minimized thanks to the commonality between the platforms. Finally, the Zenith S uses the same central library, Ofine Program Optimizer (OPO), and the AI-powered Koh Young Auto-Programming (KAP) features as the inline versions.
