■Description of Change
●In accordance with European Union (EU) and REACH regulations, copper foil manufacturers are eliminating the use of arsenic acid in their copper foil manufacturing processes. REACH aims to limit occupational exposure of Arsenic metal (As) and Arsenic Trichloride (AsCl3). This legislation is making it difficult to use arsenic compounds in the manufacturing of copper foil, ultimately banning the purchase of arsenic within the EU altogether.
●RO4003C™ laminates currently supplied by Rogers Corporation are impacted by this mandate. During 2021, the standard electrodeposited copper foil that Rogers Corporation currently purchases to manufacture RO4003C laminates will be replaced by a new copper foil grade compliant with EU regulations.
●Arsenic free copper will utilize the same equipment and production parameters as previous materials.Rogers’ internal qualification efforts indicate RO4003C laminates utilizing the replacement foils meet current performance specifications. As always, we encourage our customers to determine the suitability of Rogers’ materials for their specific application. To assist you in doing so, enclosed are Rogers’property comparisons for the existing and new versions of RO4003C laminates. Samples of the new version are available upon request.
●Due to the decreasing availability of the current copper foil grade, we request you prioritize an assessment of this change to mitigate supply disruptions and protect against rising costs anticipated with the legacy product.
