October 2006 cover

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.
    Sherman Ikemoto and Robin Bornoff

  • The Dover Deals
    'Confusion and Clarity'
    As a new owner – Francisco Partners – enters the scene, what's in store for Universal, Vitronics and Unovis?

Eastern-US: China’s New Competitor?

Parity emerges among EMS Factories from Asia, Mexico and the US.

For the first time in years we see parity in the Eastern US among EMS factories from Asia, Mexico and the US. This EMS market condition will permit American OEMs (the EMS industry refers to OEMs as customers) to have more EMS pathways to choose from. Now more than ever, such EMS assignments will require deeper investigation relating to the OEMs’ evaluation of manufacturing strategies.
