FEATURES

  • Screen Printing
    Reducing Variation Through 'Intelligent' Stencils
    Stencil variation arises from equipment error and human intervention. A study reveals sources of variation and a system for controlling them.
    Chrys Shea, Valentijn Van Velthoven, Ron Tripp and Ranjit Pandher

  • Stencil Developments
    Next-Generation Interchangeable Foils
    Said to be easier to load and unload and safer to use, new and improved foils are finding a home in high-mix manufacturing.
    Neil MacRaild

  • Cover Story
    An On-Board Mass Calibration System for Liquid Encapsulation
    For dispensing epoxy, engineers often focus on short-term pump repeatability as an equipment selection and qualification criterion, though it is useful only as a snapshot of pump capability. More important, as this investigation reveals, is the ability to quickly and easily measure and adjust the process centering over time.
    Thomas Karlinski

  • Pb-Freee Soldering
    Considerations for Implementing Lead Free
    Planning to upgrade or replace your line to meet new lead-free standards? Be sure you know what you're in for.

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.
