CML is committed to providing RoHS compliant IC products suitable for its customers' requirements. When placing orders, please ask specifically for RoHS compliant products if you require a full Pb-free compatible processing capability. This will continue to apply after July 1st 2006. Q. I have just received a tray of devices in a Moisture Barrier Bag (MBB) and note that there is air trapped within the sealed container; do I need to be concerned about this? A. To reduce the risk of device or tape-and-reel damage the CML packaging procedure is not to fully evacuate the air from the MBB before sealing. This process does not affect the MBB's resistance to moisture ingress. CML's procedure is based on the JEDEC recommendation, J-STD-033B.1 section 3.3.4. Q. Why is CML transitioning to RoHS (Pb-free) components and assemblies? A. CML has introduced a RoHS Compliant, Lead-free (Pb-free) Program in response to legislation calling for companies to utilize Pb-free manufacturing processes and components. Also, many of our customers are requesting products that utilize Pb-free manufacturing processes and components. Q. What legislation or directives have been established by the various regulatory groups? A. In December 2002, the European Union Parliament approved the content of two directives to better control the management of waste electronic equipment. The two directives are the Waste from Electrical and Electronic Equipment (WEEE) and the Reduction of Hazardous substances (RoHS). The WEEE addresses the collection and treatment requirements of waste electronic equipment for the member countries. The RoHS sets phase-out dates for the use of Pb and several other materials contained in electronic products. The RoHS requires that on July 1, 2006, the targeted materials shall no longer be contained in the electronic products above certain limits unless there is an exemption provided in the rule. Q. Is CML working in conjunction with the electronics industry to reduce the use of Pb? A. CML is working together with several industry consortia and forums to offer RoHS compliant (Pb-free) product alternatives. CML is working with its suppliers and customers to offer RoHS Compliant (Pb-free) products. Q. What are the various world standards and organizations that address the Pb-free issue? A. There are many standards and organizations that address the Pb-free issue. Here are some of the key organizations: o ANSI - The American National Standards Institute o EIA - Electronic Industries Association (http://www.eia.org/ and http://www.jedec.org/) o IEEE - The Institute of Electrical and Electronics Engineers o IPC - Association Connecting Electronics Industries o SMTA - The Surface Mount Technology Association o NCMS - National Centre for Manufacturing Sciences o NEMI - National Electronics Manufacturing Initiative o EICTA - European Information, Communications and Consumer Electronics Industry Technology Association o JGPSSI - Japanese Green Procurement Supply Survey Initiative o JEITA - Japanese Electronics & Information Technology Industries Association o PCIF - Printed Circuits Interconnection Federation Q. What is CML's definition of Pb-free content? A. A component or assembly shall be defined as containing no Pb when the Pb content of the device is less than 0.1% by weight and is not intentionally introduced. This definition is in accordance to IPC/EIA J-STD-006. Q. Is a Pb-free 260Â°C solder reflow profile recommended by CML for use with their components?
