Calumet Electronics PCBs verified RoHS compliant
Sep 30, 2005
Calumet Electronics Corp. (CEC) has verified RoHS compliance of its lead-free printed circuit boards through independent lab testing. Samples of double-sided and multilayered printed circuit boards made with FR4 material and surface plated with electroless nickel / immersion gold and immersion silver were submitted for independent verification of internal results. The tests were carried out by Intertek Testing Services of Twinsburg, OH for verification of compliance to the European Union RoHS Directive 2002/95/EC. Intertek is the world's largest products and commodities testing organization, providing Global Compliance solutions. The sample boards were tested per ASTM D5839 by grinding to a fine powder and analyzed for Cadmium, Lead, Mercury, Chromium, PBB, and PBDE content using X-Ray Fluorescence. The lowest level of detection for this method is 20PPM. The result for all samples was "a non-detectable level of restricted substances". "RoHS content limits apply to a homogeneous state. The test method used achieves that condition" said Stephen J. Marshall, CEC's National Sales Manager. "CEC has polled its material vendors and analyzed its internal production processes for compliance. Independent Lab testing confirms our internal results and provides verifiable proof of compliance".
