Hitachi High-Technologies’ modular direct-drive mounter GXH-1S with 4 gantries supplies maximized throughput for rates of up to 80,000 parts/hour – capable of also handling odd-shaped parts. The modular GXH-1JS is equipped with 2 gantries for about 40,000uph throughput. The concept of the GXH-platform allows to select for each line the best solution from 2 to up to 6 gantries. The system GXH-1S places parts on PCBs at a theoretical throughput of 80,000cph using direct-drive head technology. Reportedly, this is the industry’s top in its class, and the machine is also suitable for a wide range of component types. The system can be equipped with high-speed heads to place components from 01005 to 44x44mm, with heights of up to 12,7mm, or alternatively, with multifunctional heads handling components of up to 55x55mm in size and 25,4mm in height. For example, these are QFP, BGA, CSP, odd-shaped parts and connectors of up to 100x26mm. It is possible to combine high-speed heads with multifunctional heads in one machine. Each of the 4 heads is equipped with 12 nozzles. The XY-axes have linear motor drive, which allows high-speed and high-accuracy positioning. The high placement accuracy is achieved by using line sensors which check for the presence of components on the nozzles, and also feed back to the Z-axis for optimum placement descent. The placement system offers one-shot recognition of 12 components on the fly, and can handle boards of up to 460 x 460mm, allowing loading of 200 component types in 8mm dual-tape feeders (GXH-1JS 100 component types). The feeder system allows full component traceability. Changeover is provided quickly by use of a bank-feeder-change cart. Tape splicing is accomplished without stopping the machine. GXH-1S and GXH-1JS are ideal for both low-volume assembly with a wide variety of components, and for volume production.
