DSM's new high performance polymer Stanyl® ForTii™ has been employed by one of Europe's leading manufacturer of electro-mechanical components to design two new series of SMT pin connectors for unattended domestic appliances, thereby extending its SMT RAST connector portfolio. As a result of the trials conducted with the new polymer for this application, STOCKO Contact plans to make all their SMT connectors to Stanyl ForTii. The new series of pin connectors can be used in dishwashers, washing machines, dryers, refrigerators and cookers, all falling into the IEC 60335-1 norm due to the polymer's unique balance of properties for this apllication. They are ECO-FLEX M SMT: MS 9481, which meet RAST 5 standard and ECO-TRONIC SMT: MS 7246/7247 to RAST 2.5 standard. Both can be fully integrated into the latest printed circuit board manufacturing processes with all the advantages of the SMT technology.
According to the company, Stanyl ForTii offers excellent dimensional stability, full compatibility with lead free reflow soldering, high stiffness and mechanical strength at elevated temperatures, high melting and glass transition point as well as excellent processability in terms of flow and processing window. The high performance polymer is characterized by reflow soldering ability, which is better than PPA, very high pin retention values which are better than LCPs, stable and fast processing, very good electrical properties (CTI 600V), low moisture uptake and proven lower corrosion on molding equipment compared with competitive products. In addition, the Halogen Free V-0 material was able to pass the Glow Wire Test on end products according to IEC 60335-1.
