What is TAOS Inc Lead Free Policy?

Demand for Lead ( Pb) -Free and Green Products Due to environmental concerns of lead (Pb) contamination around the world, the need for Pb-Free solutions in electronic components and systems is receiving increasing attention within the semiconductor and electronics industries.

Texas Advanced Optoelectronic Solutions looks forward to working with our customers to provide you with the most cost-effective and reliable Green/Pb-Free product solution for your needs.

Texas Advanced Optoelectronic Solutions is currently considering approaches that would help to discontinue the use of Pb and other restricted substances in our products. Integration issues of electronics design require that Pb-Free solutions must be driven across the supply chain.

Currently Texas Advanced Optoelectronic Solutions is keeping abreast of several industry consortia addressing Pb-Free processing. These groups are evaluating Pb-Free solder alloys with Pb-Free components and printed wiring board finishes. Several of the Pb-Free solder alloys being proposed require a maximum Reflow temperature that is higher than the current peak temperature of 220-235°C for Sn/Pb.

Impact of Higher Peak Reflow Temperatures One major impact on the component packaging will be the higher peak Reflow temperature required for Pb-Free assembly, with 260°C often mentioned as the upper target. The high temperature ensures that all the components on a fully populated board will reach the melting temperature of the Pb-Free solder

Texas Advanced Optoelectronic Solutions' Commitment- Texas Advanced Optoelectronic Solutions strives to minimize the amount of disruption that might be associated with the procurement and use of Pb-Free products.

Texas Advanced Optoelectronic Solutions is committed to meeting the needs of our customers and continuing to provide world class optoelectronic sensor products, coupled with unparalleled service.

Texas Advanced Optoelectronic Solutions' plan is to be in full compliance with the lead free and RoHS directives with all products by the fourth quarter of 2005, almost a year ahead of the July 1, 2006 required date. Many devices are already available in lead free packaging.

About Texas Advanced Optoelectronic Solutions (TAOS), Inc. : Shaping the Future of Light Sensing Solutions

Texas Advanced Optoelectronic Solutions, Incorporated (TAOS) is based in Plano, Texas (a suburb of Dallas). Established in 1998, the company mission is "To Redefine Optoelectronic Solutions to Provide Cost and Performance Advantages by Creating and Managing Technology."

Historically, applications that require the sensing of light stimulus to execute a function have been implemented by either a photodiode or phototransistor – neither of which support the emerging needs for higher performance optical sensor-based applications.

Utilizing state-of-the-art technology, our semiconductor devices combine precision mixed-signal functionality with photo-detectors on the same integrated circuit to produce products with performance and cost advantages over conventional solutions. TAOS's intelligent opto sensors simplify the measurement and analog-to-digital conversion of light, and are designed to reduce the need for signal conditioning or pre-processing circuitry in light-centric systems. Our light sensing solutions improve system performance and reduce design-cycle time giving designers the flexibility and performance they require at an attractive system cost.
