FEATURES

• Test and Inspection
  Evaluating ROI of AXI vs. AOI
  A model for calculating savings from reduced DPMO against equipment investment costs clearly demonstrates that the economic benefits of either technology depend upon the board complexity, throughput, labor costs, cost of field failures and returns, and equipment performance, as well as capital equipment, programming and operating costs.
  Keith Fairchild

• Supplier Sourcing
  Prototype vs. Production Outsourcing
  When outsourcing PCBs, OEM procurement staff must fully understand the differences and nuances associated with prototype and production manufacturing, regardless of where those services are situated.
  Zulki Khan

• Board Finishes
  Pb-Free Hot Air Leveled Solder Coatings
  A series of tests from wetting balance to copper dissolution show that the most popular Pb-free pastes work better with HAL versus other common finishes.
  Howard Stevens and Nimal Liyanage, Ph.D.

• Cover Story
  Simulating Pb-Free Reflow
  Computational fluid dynamics simulation of the reflow oven makes it possible to design PCBs for Pb-free manufacturing by predicting thermal gradients during solder reflow processing.
