Desktop AOI bolsters quality for traffic management system supplier

Mek delivers THT Automatic Optical Inspection equipment for intelligent traffic management supplier

Mek (Marantz Electronics) has delivered two desktop automatic optical inspection systems for Yunex Traffic, a supplier of intelligent traffic systems. The PowerSpector GDAz systems, which now integrate into Yunex Traffic’s manufacturing facility and support the inspection of THT and solder joints, are the most versatile AOI inspection systems, reliably inspecting SMT and THT component bodies for a variety of components including presence/absence, type, polarity, offset, text and colours. Suitable for use in pre-reflow, post-reflow, post-wave and post-selective soldering, they can also be used for 2D solder paste inspection and first article inspection.

According to Henk Biemans of Mek, high-performing AOI systems have the capability to do both topside through hole components and solder inspection which means Mek was able to provide an all in one system for Yunex Traffic. “We were delighted to meet all of Yunex Traffic’ specific requirements and it is great to see the equipment in use and making a difference to the manufacture of traffic equipment that’s installed all over the world.

The introduction of the automatic optical inspection systems at Yunex Traffic is making a real difference to how it manufactures key components for a wide range of traffic systems, enabling the company to continue manufacturing to the highest quality.

The PowerSpector GDAz series targets inspection of taller THT components with a top clearance of 60mm and side cameras with a larger Field of View and 20µm resolution. A larger 3 angle lighting system secures optimal meniscus profiling in combination with increased top clearance without foregoing the maximum inspection area. A z-axis camera enables the inspection of a large variety of boards, which vary in height. Due to the software’s abundance of features/test types, false failures can be eliminated easily.
