Assembléon expanded its M-Series pick-and-place machines with the MG-8, extending its capability to deliver standalone or multi-machine line solutions to high-end, mid-volume manufacturers.
With the same look and feel as the MG-1, MG-8 is equipped with three servo-controlled FNC (flying nozzle change) heads, each carrying six nozzles, and a new area CCD camera. Component range extends from 01005 to 55 mm sq. fine-pitch to oddforms with height up to 25.5 mm. Precision z-force control delivers snap-in force for connectors and handling of 01005s.
Achieves accuracy ratings of 50 microns for chips and 30 microns for QFPs, placement speed for ICs and QFPs is 8.4k cph. Has twin board support system with double, independent push-up units.
Accommodates 90 smart feeders along with stick, bulk and tray feeding solutions. The feeders are equipped with RFID technology to simplify machine set-up and provide real-time component inventory management. Feeder trolleys can be set up and verified off-line for fast changeover. A large component sequencer contains 60 pallets, with two in-line loading heads doubling the rate of delivery of components to the machine. An automatic tray stacker holds up to 30 trays in quick-change containers.
Coplanarity system checks three components simultaneously; a side viewing camera option verifies 01005 or 0201 presence at the nozzle while the heads fly over the line array camera for component recognition. A nozzle cleaning system prevents nozzle contamination for improved quality and reduced maintenance.
The Quadris-S four-gantry placement machine, with built-in turret technology, leverages advanced motion controls to achieve a high throughput-per-machine footprint and a wide part range without changing heads. Has 100ppm final placement performance. Combines 80,000 cph placement performance, 0201 to 44 x 44 mm component range, support for tape and tray feeders including dual-track feeders, automatic board centering between feeder banks, on-the-fly gang recognition and bank feeder change. In addition to high-speed placement of SMDs as small as 0201, fine pitch capabilities support BGA or leaded packages of 0.5 mm pitch, with ball diameters down to 0.3 mm or leads 0.18 mm wide.
“The Quadris concept concentrates turret-style and gantry placement capabilities into a far smaller footprint than discrete inline machines capable of comparable throughput,” said Prashant Vithlani, Product Manager. “Quadris-S now extends this performance-per-square-meter advantage by boosting throughput and supporting an even wider range of component sizes. This also simplifies scheduling of assemblies, and enhances line balancing and utilization because fewer large components must be placed further down the line.”
Includes direct drive, linear motion, linear sensor and gang recognition. Options include bad board reject, extended BGA/CSP options and 610 x 460 mm board handling. Other options: library data teach, pattern program data teach, automatic component validation (ACV) and an offline feeder setup station.
Comes with UCT-53 offline programming software, and runs on Windows XP.
High-speed linear motors with 0.0048 micron resolution ensure fast, accurate x-y motion. Inter-axis correction control for the y-axis, combined with twin drives, ensure accuracy and repeatability. Each gantry has a compact, direct drive 12-spindle head featuring low weight and inertia, high resolution, high speed and high reliability. Has theta resolution of 0.0027° and a z-height resolution of 1 micron. On-the-head linear CCD sensors provide automatic placement height optimization. The sensing system can detect missing and vertical components, and measures component thickness, to automatically adjust the height control.
Non-stop on-the-fly gang recognition of up to 12 components at high speed enables synchronous control of all four x-y gantries. Productivity Shift board transfer system centers the PCB between feeder banks for optimal balancing across the beams. Bank feeder change and splicing capabilities facilitate rapid replenishment and product changeovers.
LPKF MicroLine 350Ci laser system provides stress-free depaneling of assembled PCBs. Features higher cutting speeds for mechanical depaneling methods; requires no expensive tooling. The laser technique leaves no residual dust on the PCBs and will not damage sensitive components. Cuts any contours while maintaining higher precision than mechanical routing systems. The non-contact and stress-free cutting process, with a very small beam diameter, allows components to be placed close to the edge of the board for optimum utilization of the panel. Can be integrated in an existing SMD production line, or used as a stand-alone work station. LPKF Laser & Electronics, lpkf.de
