Market Background and Product Outline

In recent years, various products from home electronics, personal computers, to mobile phones have become miniaturized, high-density, multi-functional, and diversified. In addition, their product cycle is becoming shorter. In line with these trends, the electronic component mounting process of these products requires efficiency and flexibility to allow both various product types in small quantities as well as mass production to be carried out using the same production line, instead of simply mass-producing one product for over an extended period.
With even further miniaturization and diversification of electronic components, a recent trend has been to have multiple heads (such as a head that mounts only small components at high speeds, or a head designed for mounting components that are large and odd shaped). And in order to handle a wide range of components while maintaining productivity, these heads were replaced according to the component characteristics and production quantity. However, there have been various issues associated with employing interchangeable heads. For example, head replacement may cause production time loss, as well as investing loss because of the underutilized expensive spare heads cost. Furthermore, if there is even a single large component that needs to be mounted on a PCB, a general-purpose low speed head may have to be used, which does not allow high-speed mounting of smaller components, which will then cause a loss in efficiency due to lower throughput and/or bottlenecking.
In order to solve these issues, Yamaha Motor has been developing and marketing its YS Series with "1 head solution" as the ideal concept, where a 1 type of head can provide compatibility from small chips to large components.
The new Z:LEX YSM20 is developed as "the ultimate" high-efficiency modular mounter that pursues the "1 head solution" ideal further: it flexibly and efficiently caters to a variety of production processes without the loss caused by head replacement, while achieving the world's fastest mounting speed in its class.
In addition, our advantage of offering a full lineup of surface mount equipment, including printers, dispensers, surface mounters, and inspection systems, allows an in-line mounting system to be set up seamlessly. Thus Yamaha Motor has achieved an improvement in production efficiency and quality for the entire mounting line.

Product Features

1) Two types of beam variations
The fundamental structure of the new Z:LEX YSM20 features a highly-durable, precision-made monocoque frame that is designed to maintain mounting accuracy over extended periods. In addition, the new model employs a universal platform, where customers are able to select from either the 2-beam or single-beam X-axis configuration to meet demands for mounting capacity, versatility and budget. This provides more freedom in configuring mounting lines.

2) Featuring two types of newly-developed heads that are based on the "1 head solution" concept
Compatible with super-small components (such as the 03015 (0.3mmx0.15mm) size) to large components
The two types of new heads are developed with the ideal of the "1 head solution" concept, which allows compatibility with a wide range of components at high speeds without the need for head replacement. The new heads can help reduce downtime due to head replacement, as well as expensive costs for purchasing spare replacement heads. Both head types come standard with side-view recognition function, enabling the detection of the existence of components as well as its pick-up orientation and tilt status. In addition, the unit’s nozzle self-diagnosis function ensures a high level of mounting quality and reliability.
• HM (High-Speed Multi) Head: An all-round "high-speed multi-purpose head" which provides the world's fastest mounting speed in its class, as well as the versatility to handle super-small chip components such as the 03015(mm) size, as well as larger components of up to L45mmxW100mmxH15mm.
• FM (Flexible Multi) Head: An "odd-shaped components head" which is compatible with load controls, and handles super-small chip components such as the 03015(mm) size, as well as larger and taller components of up to L55mmxW100mmxH28mm.

3) Components supply device with excellent operability
• Compatibility with the electric-drive intelligent tape feeder "ZS Feeder" and "SS Feeder" that employ microcomputer controls to provide a high-speed components supply and high-accuracy components positioning. A maximum of 140 units (max. 8mm tape feeder conversion) can be installed. (When using the fixed plate; up to 128 units can be set for feeder carriage options.) When the "ZS Feeder" is used, a non-stop feeder replacement option can also be selected.
• The Z:LEX YSM20 is available with the sATS30 30-step fixed automatic tray supply unit, and the cATS10 10-step automatic tray supply carriage unit which allows for replacement with feeder carriages. A mixture of the two different tray supply units can be installed, and up to two tray supply units can be installed onto one YSM20 device.

4) Ability to select the conveyor system according to the production process
The conveyor system can be selected from dual stage (available for the 2-beam option only), dual lane, or single lane according to production volume and circuit board size. This enables the Z:LEX YSM20 to be compatible with a minimum circuit board size of L50mmxW50mm, and a maximum circuit board size of L810mmxW480mm (for dual stage or single lane) or L810mmxW230mm (for dual lane).

5) An excellent mounting speed of 90,000 CPH (under optimum conditions as defined by Yamaha Motor)
Through the use of the next-generation servo system featuring a high-speed control technology similar to that found in Yamaha Motor's high-end model "Z:TA YSM40'. Furthermore, other detailed refinements have been made, such as the newly-developed Z-axis linear motor, the use of a miniature scan camera unit, and miniaturization and weight reduction of the head. As a result, the new model has increased mounting capabilities. With the 2-beam, 2-head configuration (HM spec) and under optimum conditions as defined by Yamaha Motor, the Z:LEX YSM20 achieves the world's fastest mounting speed in its class of 90,000 CPH. This is an improvement of over 20% compared to the YS24 mounter.
