TI's RoHS "Gold" Aids Customers in RoHS Transition

Aug 15, 2005

DALLAS (August 15, 2005) - Texas Instruments Incorporated (TI) (NYSE: TXN) announced the implementation of its RoHS (European Union Restriction of Hazardous Substances) "Gold" strategy for its integrated circuit products. Developed to offer easy solutions to RoHS component transition challenges, RoHS "Gold" provides customers with the preferred finish for lead-frame based products, Nickel-Palladium-Gold (NiPdAu), which means no "tin whiskering" worries, as well as unique part numbers for easy Bill-of-Materials (BOM) management and easy on-line access to key material content information.

"TI's RoHS 'Gold' strategy was developed to help make the RoHS transition process easier," stated Eric Williams, Manager for TI's Pb-Free Program Office. "Our customers have routinely highlighted the importance of these 3 elements in order to meet their time-to-market needs."
TI first implemented the Nickel-Palladium based finish to its Logic ICs in 1989 and has since shipped over 30 billion units into the market. The NiPdAu finish is TI's primary RoHS compliant finish for lead-frame based products. Today, over 98% of those products have already been converted to the NiPdAu finish which is also backward compatible with traditional "leaded" manufacturing processes.
TI's RoHS "Gold" strategy also features unique part numbering which makes it easier for customers to manage their new RoHS compliant BOMs, ensuring RoHS compliant parts are ordered, received and board-mounted properly. For lead-frame based products, TI has adopted a two-character suffix based on the JEDEC JESD97 solder finish codes. For example, the standard part number "ADS1286UA" now has a RoHS compliant, unique part number "ADS1286UAG4". For BGA-based products, the RoHS compliant version is not backward compatible, so a different unique part numbering scheme is used that includes a "Z" in the package suffix. For example, the "leaded" part number "PCI1620GHK" now has a RoHS compliant, unique part number "PCI1620ZHK."
The final element of TI's RoHS "Gold" strategy is to provide customers with easy access to key RoHS related information, including a best-in-class material content search tool with downloadable results, as well as a material declaration certificate, application notes and more. (See www.ti.com/leadfree.) TI recently was the only semiconductor supplier to receive a "best" ranking of "5" according to RoHSwell.com. An independent third-party resource, RoHSwell.com ranks suppliers websites based on the depth and breadth of RoHS related material.
