Martin has launched the dream team for QFNs at the SMT 2006 show in Nuremberg, Germany.
With a Rework-Dispenser and Auto-Vision-Expert, the company presented an innovative machine pair for solving demanding soldering tasks. To ensure the required quality in reworking QFN components, Martin proposes not to rely solely on residual solder and to re-ball the QFNs, or apply solder paste onto the printed circuit boards 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 uncompromising camera controlled positioning of the components. This rework method, which includes the application of solder paste, exactly matches the technological state of the in line mass production process.
