2004/02/2 2004/02/2 Murata RoHS Lead Reduction Activities 23rd September 2004 Agenda Welcome Introductions Background Lead Free Manufacturing The Legislation Manufacturing Issues Murata Activity Direction Part Numbering Changes Distribution Stock Rotation Questions Answers Background Lead has been known to be a poison for many centuries. Despite this lead has been the primary constituent of solder since the beginning of the electronics industry. Recently environmental activists have been working to eliminate lead from many products and ban the dumping of equipment containing lead in land fill sites. For Non Chemists Common chemical symbols Copper Cu Gold Au Lead Pb Nickel Ni Palladium Pa Silver Ag Tin Sn Lead Free Manufacturing What is really meant by these terms? Lead free manufacturing Lead free terminations Lead free components We see confusion and poor understanding in the industry! Lead Free Manufacturing The production of PCB’s using solder containing no lead and components with lead free terminations. Lead Free Terminations In most cases when customers ask for lead free they really mean lead free terminations. This means components with terminations and/or legs containing no lead. A typical replacement for lead would be tin although many others are available. Lead free solders have a higher melting point than traditional solders and this places additional thermal stresses on components. Termination and packaging materials? Lead Free Components This is a much more difficult concept! Most ceramic materials contain some lead. Piezo electric components won’t work unless they contain lead!! Components containing glass and many plastics will also contain some lead. The Legislation (1) The WEEE Directive By 13th August 2005 Producers will be responsible for financing the collection, treatment, recovery and disposal of Waste Electrical Electronic Equipment (WEEE) from private homes and other users By 31st December 2006 Producers
