RoHs and WEEE ComplianceThe European Union legislation known as the Entitled Waste Electrical & Electronic Equipment (WEEE) and Restriction of Hazardous substances (RoHS) have issued new directives for environmental health & safety protection regarding selective treatment for materials and components of waste electrical and electronic equipment. In support of our commitment to comply with these directives, we at Falco understand the direct link between these important issues and the quality of our products.These directives are aimed at reducing the hazardous homogeneous materials content in electronic products as well as increasing the recycling efforts for these products and take effect July 1, 2006. None of our products are to intentionally use any of the following substances in the homogeneous materials:
For the control of this issue we require SGS reports from each vendor and also for other substances non regulated by RoHS we count with a “Supplier Survey For Statement Of Hazardous Material Content” to understand how they are managing environmental legal compliance and the hazardous materials that are contained in the components and products that they supply to us.
RoHS Level in FalcoFalco has defined RoHS Products in two levels identified as RoHS I & RoHS II (Super RoHS). This second categorization has been designed based on several incoming surveys from our customers where other substances other than the six required by RoHS, are defined as banned, controlled and/or reported.RoHS I: Our Products identified with this level comply with the limits of the hazardous substances as described by directive 2002/95/EC. RoHS II: or Super RoHS, our products identified with this level are in compliance with the maximum limits of the hazardous substances compliance with the maximum limits of the hazardous substances required in RoHS level I plus the substances for environmental health & safety protection as highlighted in Table (1) shown further on this text.

Tin Whisker Qualification and Mitigation ProcessA potential reliability problem exists with lead free tin plated components (especially in 100% Sn) due to the phenomenon of "tin-whiskering" which may cause electrical shorting between leads of the same component or adjacent components, especially for fine pitch components or closely spaced parts. At this time, there is no sure method to guarantee the elimination of tin whiskers over the life of a product. FALCO realizes the importance of avoiding potential tin whiskers and thus we are using a Lead free alloy that is exempted from the tin whisker test as per the National Electronics Manufacturing Initiative (NEMI). The preferred Falco alloy for second level interconnection are:
1. Matte tin (Sn 100%, carbon content 0.005%-0.050% and Grain size 1µm-5µm), 8µm of tin film minimum or thicker. Product IdentificationThe marking of Falco Products is based on JEDEC Standard No.97,which requires to provide a distinctive symbol and labeling format to identify those assemblies, components or devices that are totally Pb-free. It also provides for identification of certain types of Pb free materials. Falco Product identification will show Pb Free category, RoHS compliance and Pb-free identification label in the outer Box. Please contact sales department for any further requirement.
Definitions1. Homogeneous material: a unit that can not be mechanically disjointed in single materials or any materials that is not mechanically divisible (disassembled, cut or ground) into separate material constituents. The term “homogeneous” is understood as “ of uniform composition throughout”2. 2nd Level interconnect: The interconnect made by the attachment of the device/component to the printed circuit board. 3. Pb-free category: A category assigned to Pb-free components, boards, and assemblies indicating the general family of material used for 2nd level interconnect including solder paste, lead/terminal finish, and terminal/alloy solder balls.
