This pick-and-place system is capable of placing 3-D-MID technology. Is based on inline pick-and-place FLX2011-LCV system. Is completed by a palette transport system, a five-axis robot and a dispensing head with two valves. A free-motion robot arm is located in the chassis and grips the 3D-MID module from the transport system. Dispensing head is equipped with two individual touch-less dispensers: one for precise dispensing of solder paste, the other for accurate metering of fast-curing adhesive. Solder paste is applied to the electrical contact surfaces. Glue is dispensed on other locations to hold the SMD part until the reflow process and absorb mechanical stress. SMD components are placed with a vacuum tool and are picked from feeders, measured and aligned by an optical centering system, then placed to contact surfaces. Standard components are aligned on-the-fly with a laser system. For BGA, QFN and QFP, Cognex Vision is used.
