METROLOGY ROUND-UP
ADVANCES IN MEASUREMENT Automatic optical inspection 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. These include 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’s 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,” said Biemans. 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 three-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 features/test types, false failures can be eliminated easily.
Plug-and-play LVDT gauging system The new induSENSOR DTD-xG8 series from Micro-Epsilon is a complete preconfigured and calibrated inductive measuring system that consists of a DTA gauge (inductive LVDT probe) and controller integrated into the sensor
cable. The cable is suitable for use in drag chains. The factory-calibrated system is fully linearised, enabling fast, easy plug-and-play installation. The induSENSOR DTD inductive
sensor system is based on the proven LVDT (linear variable displacement transducer) measurement method. The fact that the sensor and controller are permanently connected to each other allows the system to be pre-adjusted and calibrated at the factory so that the system can be installed and used straight from the box. The system offers extreme precision and delivers high signal stability and resolutions down to the sub-micrometer range. Due to its high temperature stability, resistance to shock and vibration, as well as insensitivity to dirt and dust, the induSENSOR DTD is suitable for use in harsh industrial environments. The system has an adjustable
current and voltage output, as well as an RS485 interface, which are output via a standard industrial connector (5- pin, M12). Parameter settings are carried out using freely downloadable software and an optional USB cable. Modern fieldbuses such as Ethernet, Profinet and EtherCAT are supported via optional interface modules. The sensors are available in four measuring ranges of ±1 mm, ±3 mm, ±5 mm and ±10 mm.
