Unrivalled quality. Why it is vital to choose the best technology

At the heart of the state-of-the-art SMT line now in action at C-LED’s factory are two Yamaha Z:LEX YSM20 dual-stage two-beam mounters.

Each machine is capable of placing components down to 03015 size, at up to 90,000 cph, on boards as large as 810mm x 490mm..


The YSM20s deliver the perfect combination of high-volume placement and the ability to handle our high-mix production needs. We usually need to do two to three product changeovers per day, typically placing over 300,000 LEDs plus associated components such as control ICs, passives and connectors..

To take care of quality on the other side of the soldering process, C-LED has chosen a Yamaha YSi-V 3D Automatic Optical Inspection (AOI) machine. This gives us the greatest flexibility to inspect prototypes or production units as and when the company needs. The YSi-V provides the benefit of Yamaha’s well-known multi-angle, multi-wavelength inspection using red, green, blue and infrared sources, which ensures ultra-dependable defect detection with minimum false calls. In addition, the machine’s built-in laser height inspection is extremely effective at detecting any coplanarity errors that can indicate problems with mounting or soldering processes.

C-LED’s Yamaha YSi-V 3D AOI is used offline to inspect assemblies at any stage of development or production.

At every stage of the production process, we use only the very best technologies. This is what happens behind the scenes. The visible benefits are what the customer sees in terms of product quality and lifetime reliability.
