A Supply-Chain Engineering Solution
Most EMS companies have seen limited success providing design-related services to OEMs. A new method known as "Virtual Cluster" proposes to bring together best-in-class companies for design project engineering and supply-chain functions, to reduce cost and time-to-market.
Pb-Free Reflow and Rework
While long-term reliability evals are ongoing, NEMI has found that when using optimized tools and processes carried out by experienced personnel, SnAgCu reflow forces a big hike in melt temperature. A list of findings and recommended changes for lead-free reflow and rework.

Large Format Rework for Eutectic and Lead-Free Applications
Meeting specific rework needs of disparate boards requires a move away from one-size-fits-all equipment. The combination of full-bottom-panel, low-mass IR heating, stationary board fixturing and gantry-type reflow can eliminate many warping problems faced when reworking large BGA boards.
Lead-Free First-Article Inspection
Smaller process windows of lead-free alloys put greater demands on soldering equipment and inspection equipment and procedures. What are the typical process concerns associated with LF alloys for first-article OI and line qualification?
