The Juki SMD placement machines R-series (KE-2050R, KE-2055R, KE-2060R and FX-1R) reportedly focuses on low cost of ownership. All assemblers are equipped with bad-mark recognition, and additionally, can be equipped with the revised intelligent-feeder system, improved setup-control system, self-calibration system, as well as a multitude of more features. The KE-2050R is a flexible high-speed placer, equipped with a quadruple-placement head and multi-laser-centering, reaching a throughput of 13,200cph with an accuracy of 50µm at 3-sigma. The precise laser measurement in all three axes supports placement of 0201-parts. The KE-2055R features an additional vision system for the quadruple-placement head, and thus is ideally suited for placing µBGA and conventional components up to a maximum size of 20 x 20mm or 11 x 26,5mm. It reaches a throughput of 12,500cph for chip components and 3,290cph for vision-centered items. The KE-2060R is a highly flexible all-rounder, placing the complete range of SMDs and being equipped with a quadruple-placement plus a high-precision head. As with the KE-2055R, the quadruple head can optionally be equipped with laser and vision recognition. This almost doubles the throughput for vision-centered components to 3,400 cph. The high-precision head allows for a placement accuracy of 30µm at 3-sigma. High flexibility and throughput makes it the ideal solution for single-module lines, as well as for applications with several high-speed modules. The FX-1R is the fastest member of this family and reaches 25,000cph. The horizontal axes are driven by precise and fast linear motors. The arrangement of board fixture and of the two placement heads on the XY-axes minimizes idle times to virtually zero: while one head is placing, the other is picking components simultaneously. A further advantage of this concept is its simplicity and reliability if compared to conventional and complex dual-head configurations. Although the FX-1R is stuffed with technological improvements, it is compatible with all earlier Juki placers – as are all modules in the R-Series.
