R estriction o f certain H azardous S ubstances Definition * 07/16/96
3
POLICY Retention of Current Models
Creation of New Models for RoHS Compliance Drop-in replacement
4
WHY ?? Mini-Circuits is ISO Certified and is committed to a Greener environment Restricted Substances are potential hazards to health and the environment INCREASING CUSTOMER DEMAND
5
Standard Mini-Circuits will meet the requirements as stated in the European Union Directive (2002/95/EC) Mini-Circuits will provide compliant parts prior to the July 2006 deadline Policy includes ‘total’ compliance, not just Lead-free
6
Restricted Substances
Lead (Pb) - platings, surface finishes Mercury (Hg) - not applicable Cadmium (Cd) - capacitors, ceramics Hexavalent Chromium (CrVI) - chromate conversion finish of aluminum PBB - flame retardant PBDE - flame retardant
7
Customer Inquiries Web Page devoted to RoHS/Pb-free
Includes Letter of Introduction Policy FAQ Sheet List of RoHS Compliant Model Families Material Declarations, in Excel format (see sample at end of slide)
8
Product Identification
All RoHS Compliant models will have part numbers ending in “ + “ suffix. “+” suffix to appear on models where marking is done. “ + “ Part numbers and symbol will appear on all labels and packaging. Implementation of JESD97 2nd level interconnect (e) labeling. Pb

Alternatives Getting the ‘Lead Out’ SAC solders
Matte Tin over Nickel on Leadframes and Chip Components ENIG (electroless nickel immersion gold) on ‘soft’ PCBs Tin/Silver/Nickel on MMIC leadframes Tin/Silver on pin headers
10
Alternatives (cont’d)
Cadmium Cadmium-free capacitors Cadmium-free ceramics Hexavalent Chromium Trivalent “Alodyne” Phosphating Gold Plating
11
Process/Reliability Issues
Pb-free solders require higher Peak Reflow Temperatures. RoHS Compliant parts will meet J-Std-020C Reflow profile requirement. No change in MSL is anticipated Testing for Joint Reliability and Tin Whiskers
