MARTINs Dream Team for QFNs |
Press release 3/2006 |
|
|
Wessling, June 2006.
MARTIN GmbH launches the Dream Team for QFNs at the SMT 2006 show in Nuremberg, Germany. With the Rework-Dispenser and the Auto-Vision-Expert the company presents 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 from MARTIN, consisting of the improved Rework-Dispenser and the Auto-Vision-Expert, 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.

Clever Nozzle Copes With Height Differences |
|
The MARTIN Rework-Dispenser is the ideal equipment 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 & Dispense" method.
