'Dream Team' for QFNs shown at expo

9 August 2006 Manufacturing / Production Technology, Hardware & Services

Martin launched its 'Dream Team' for QFNs at the SMT 2006 show held in Nuremberg, Germany, recently. With its Rework-Dispenser and its Auto-Vision-Expert, the duo comprises an innovative machine pair for solving demanding soldering tasks, says the company.

QFNs (quad-flat-no-leads) appear in increasing numbers in new electronic products. These components, without solder content, are somewhat cheaper than CSPs, which are provided with solder balls. The problem, especially in rework, is the missing solder reservoir. The Dream Team supports the user in reworking QFNs by automatic height measurement when dispensing in tight spaces and the firm camera-controlled positioning of the components. This rework method, which includes the application of solder paste, exactly matches the in-line mass production process. To ensure the required quality in reworking QFN components, Martin suggests to not rely solely on residual solder, but to re-ball the QFNs or apply solder paste onto the printed circuit boards.

Nozzle copes with height differences

The Rework-Dispenser is ideal for dealing with individual components. With the integrated height sensor, the gap between each pad and the dispensing nozzle is accurately established and precisely the required amount of solder paste is dispensed. There is no more need for stand-off pins with this new 'measure and dispense' method, says Martin.

Automatic placement

The Auto-Vision-Expert is unique in its approach to placement and soldering of components. With the high resolution camera and the motorised axes movements, the placement process can be observed at ease from the monitor. Users can be confident in reliable results, as the alignment does not depend on complicated calibration procedures, explains Martin. Instead, the fixed camera controls the process right up to the placement of the component.
