Definition

• R estriction
• o f certain
• H azardous
• S ubstances

3
POLICY

• Retention of Current Models
• Creation of New Models for RoHS Compliance
• Drop-in replacement

4
WHY ??

• Mini-Circuits is ISO-14001 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

Customer Inquiries

• Web Page devoted to RoHS/Pb-free
• Includes Letter of Introduction
• Policy
• FAQ Sheet
• List of RoHS Compliant Model Families
• ROHS_at_MINICIRCUITS.COM
• Material Declarations, in Excel format
• (see sample at end of slide)

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.

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 (contd)

• 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
