Hitachi High-Technologies Europe GmbH will introduce at Productronica in Munich the new modular direct drive mounter GXH-3, which is, with maximized throughput, capable of placing components at ultra-high speed and handling odd shape parts.

Besides the increased throughput of 95,000 cph, the optimized GXH-3 has been improved in comparison to the current type GXH-1S in regard to operability, prevention of operation errors, easier handling and visibility.

At the same time optimized modular expansion GXH-3J is introduced. While GXH-3 is offering 4 gantries, the GXH-3J is equipped with 2 gantries. The modular concept of the GXH-platform allows to define for each production line the best configuration, e.g. with 2 gantries (GXH-3J), with 4 gantries (GXH-3) or with 6 gantries (GXH-3 plus GXH-3J). The GXH-3J can be used to increase the componenthandling spectrum, to increase the production throughput and to optimally expand the existing production capability according to the demand.
 
The HITACHI direct drive modular system GXH-3 places chips on PCBs at a theoretical throughput of 95.000 cph (GXH-3J: 47.500 cph) using “direct drive head technology”. This is not only the industry’s top in its class, but the machine is moreover suitable for a very wide range of component types. This new placement system is highly capable. It can be equipped with high-speed heads to place components from 01005 to 44x44mm and components height of 12,7 mm, or alternatively, with multifunctional heads, which allow handling of components up to 55x55mm and a height of 25,4 mm. Possible component packages are QFP/ BGA, CSP, odd shape components and connectors up to 100x26mm. As a result of the interchangeable and modular concept, it is also possible to combine high-speed heads with multifunctional heads in one machine.

The GXH-3 offers 4 gantries, each with one placement head. Each of the 4 heads is equipped with 12 nozzles. The XY-axes have linear motor drive, which allows highspeed and high-accuracy positioning. HITACHI achieves high placement accuracy by using its well-proven line sensor, which not only checks the presence of the component on the nozzle, but is also feeding back to the Z-axis for optimum placement descent. This placement system offers one-shot recognition of 12 components on the fly. Furthermore the GXH-3 can handle boards up to 460 x 460 mm (optionally 610 x 460 mm) and allows loading of maximum 200 component types in 8mm dual tape feeders (GXH-3J: 100 component types). The intelligent electronic feeder system allows full component traceability. Changeover is quickly done by use of a bank feeder change cart. Tape splicing can be done without stopping the machine. GXH-3 and GXH-3J are ideally qualified for both low volume batch production with a wide variety of components, and for mass production. The modular concept allows both full flexibility and maximum productivity. www.hht-eu.com
