1) Improved productivity and accuracy due to revised XY axis design
Introduction of leading-edge control technology together with the adoption of an off-set type linear motor through a logic-based design revision of the XY drive axes. The supporting beam of the head has been made more lightweight and with reduced vibration. Because of this, the effective tact delivers a 5% productivity improvement on average over existing models. At the same time, mounting accuracy of ± 25um (3sigma), which corresponds to handling the extremely small-sized 0201 chip components, has also been achieved.
2) Compatibility with Current sigma Series Model
Compatibility of the main options with the current model ?-F8 has been maintained, including with the head, nozzle, nozzle stocker, and tape feeder. This allows for users of the current ? series to continue to use their specialized equipment as they implement this new equipment hassle free.
Z:LEX YSM20W New Model Features
1) Outstanding versatility thanks to industry top level PCB adaptability
Handles a maximum PCB width of up to 356 mm where the same width PCB is being conveyed at the front and rear while in dual-lane specification mode. In this case, the head will continue to function without front or rear head strike for up to a maximum PCB width of 324 mm achieving high-efficiency implementation without loss.
In single-lane specification mode, PCBs can be conveyed at up to a maximum length of 810 mm, maximum width 742 mm, a conveyable weight of up to 10 kg, and a thickness of up to 8 mm. This new model is also compatible with a wide range of extra-large-sized PCB's and jig conveyance etc., including for automotive products, industrial, medical, power devices, and LED lighting.
