MX-Series SMT assembly systems are for medium- to high-volume operations. They feature real time vacuum monitoring prompts the operator (without stopping the machine), when a job is loaded and when running. When it detects the vacuum threshold in the heads is low, it also alerts the operator. Each feeder, in addition to storing part number, lot code and feeder pitch, carries its presentation performance forever.

The series consists of two systems, MX-310 and MX-240. Features include:

• Placement accuracy of 33 µm at 4-sigma accuracy for QFPs, BGAs and CSPs.
• A line scan camera inspects large parts and odd-form.
• A coplanarity checker inspects parts for pre-placement lead warpage.
• Improved illumination on all systems allows for more LEDs (both collimated and oblique), resulting in improved recognition of the full component range.
• Light settings invoked for each part, preventing machine stoppages from "false failures" due to non-uniform lighting. 
• A flip-chip camera, for processing FC devices.

Also, the MX-310 has a four stage transport system that enables 25% more speed when processing 8" x 12" boards; a head mounted servo driver/motion controller that permits machines to run at higher speeds through faster response times and eliminates 75% of the cabling from the head to the bottom chassis.

The MX-240 has a closed-loop force control head to minimize impact force. These spindle-mounted sensors operate in concert with high-response vacuum control for force control; a high-speed tray presentation, a side-mounted P40TSU (40-tray shuttle unit) that presents tray fed components without limiting feeder space or board size; and can be configured with two units, which allows 170 unique part numbers to be held per machine.

Tyco Electronics will premiere the Mirae MX-Series at Assembly Technology Expo, Sept. 26-30, 2004.
