Release of the new Yamaha high-speed dispenser “YSD” -Major advances in tact time and dispensing performance-

May 29, 2013

Yamaha Motor Co., Ltd. has developed the new high-speed dispenser model “YSD,” boasting the industry’s highest levels of tact time at 0.07 sec./shot plus improved versatility. This new model will be released for sale on July 1, 2013.

The YSD comes to market as the successor to Yamaha’s “YGD” dispenser model that won a reputation for answering market needs for compactness and low cost while achieving the industry’s highest levels of dispensing speed and precision at the time of its release in April 2004. The YSD achieves major improvements (over 20% compared to the YGD) in tact time and dispensing performance.

In a conventional production line for mounting electric/electronic components on printed circuit boards (PCB), a dispenser for surface mount technology (SMT) systems is a special machine used to apply adhesive that temporarily holds the parts to be mounted on the PCBs in place. The YSD, however, is designed to perform a variety of dispensing functions in addition to temporary adhesive application, while also providing the capacity to handle large-sized PCBs of up to 510 mm in length and 460 mm in width, coming with a touch panel as standard equipment and other functions to increase versatility and operability. Environmental and safety concerns are also addressed with measures such as meeting CE marking requirements and operational compatibility with a low compressed air level of 0.45 MPa.

Using the YSD together with Yamaha’s high-speed modular type surface mounters makes for a surface mounting production line that not only has a high level of productivity, but is also very efficient in its use of floor space.

Plans call for the new YSD to be on display at the JISSO PROTEC 2013 (15th Jisso Process Technology Exhibition) scheduled from June 5 to 7, 2013 at the Tokyo Big Sight exhibition center (Koto Ward, Tokyo).

Market Background and Product Outline

Currently, demand is still high for the dispensers that apply adhesive to temporarily fix surface-mount parts and components onto PCBs. At the same time, there is a strong demand for models that can accommodate the increasing density of part concentration on today’s PCBs. Furthermore, in addition to adhesive application, there are new uses emerging such as application of supplementary solder paste to large lands in the case of mounting complex mixes of extra-small chips and large-size components. Attention is also focusing on the potential of dispenser technology to perform other tasks such as permanent bonding of parts like shield cases, sealing and coating of things like insulation, dam and fill applications, etc.
In recent years, demand in the SMT market has become much more sophisticated and diverse in its calls for greater productivity. To answer this demand, as Yamaha’s first new dispenser model since the YGD released in April 2004, the YSD is a high-speed, high-performance, multi-functional model that achieves major improvements in tact time and dispensing performance while providing new functions such as non-contact dispensing, line dispensing and more for increased versatility.
