• Cover Story
  Cleaning Up after Pb-Free
  Lacking field data for no-clean Pb-free solders and confidence in accelerated aging tests? An expected increase in contaminants means effective cleaning is the only way to guarantee an assembly won't fail due to residues.
  Leigh Jansen

• Process Management
  Concurrent Manufacturing in an EMS Environment
  The changes and precautions to take down the line during implementation of Pb-free manufacturing. This review covers printing, placement, soldering, inspection, materials management, compatibility and marking.
  Amey Teredesai and Tony Batalha

• Soldering Materials
  Pb-Free Solder Assembly for Mixed-Technology Boards
  While assemblers push for a single alloy throughout all soldering processes to avoid cross-contamination, tests show no joint degradation related to the mixing of SN100C and SAC alloys.
