Alliance Memory is very concerned with the use of Lead (Pb) in our SRAM products and has put in the necessary effort to meet all compliance deadlines. The European Union has established a phase-out date ( July 1, 2006 ) for Lead (Pb) in electronic products with some exceptions. We are currently prepared to provide support to all our customers to meet these new legislative requirements.
Legislative Activities
- European Union — RoHS: restricts use of Pb, mercury, cadmium, hexavalent chromium and certain halogenated flame retardants (PBB and PBDE) by July 2006.
