Taisol Electronics, the second largest Taiwanese memory card manufacturer with branch offices in China, Singapore, Japan and the US and worldwide distribution, has commercialised halogen-free V-0 Stanyl ForTii for its 5-in-1 memory card socket, readily usable for memory stickTM, SD CardTM, MMCTM, Smart MediaTM, and xD-Picture CardTM.

These 5-in-1 memory card connectors are already used in printers produced by one of the leading top two OEMs. Such memory card connectors are a central interface in today’s electronics. Applications include notebooks, desktop PCs, card readers, LCD projectors, monitors, etc.

Taisol was looking for an improved material that could reduce warpage in their 5-in-1 memory card connectors. Although the previous solution, a GFR PA9T, was specifically developed as a low warpage grade, Stanyl ForTii F31 could reduce warpage by an astonishing 50 per cent in comparison.

Amin Hsu, assistant general manager at Taisol Electronics China, says: “Thanks to its high stiffness and related excellent low warpage properties after reflow, we were not only able to fulfill our customers’ requirement for a flame retardant, reliable card connector, but could also offer an entirely halogen-free solution while reducing their total cost.

Dramatic improvement

Ong See Wee, senior application development manager at DSM Engineering Plastics in Asia, who worked intensively with Taisol, commented that a dramatic improvement in coplanarity versus competitor materials was a significant improvement to DSM customers.

“ForTii has been developed to keep a high stiffness even at elevated assembly temperatures above 300°C,” he said. “ForTii drastically improves warpage yield loss and is outperforming any other polyamide as well as PPS and LCP. The unique properties of ForTii are also helping manufacturers to reduce their manufacturing costs.”
