    Industrial Health
    Evaluation of Employee Exposures at a PCB Plant
    A confidential employee request for a Health Hazard Evaluation (HHE) at an electronics manufacturer specializing in PCB fabrication and assembly explains how third-party audits are initiated and reviews best-in-class controls for maintaining factory worker health.
    by Srinivas Durgam, Chandran Achutan, Ph.D., Carlos Aristeguieta, M.D., and Maureen T. Niemeier

    DfT
    Smoothing the Layout to Test Flow
    When layout and test take place under the same roof, determining the right strategy to increase test coverage for a given product becomes much easier, and ensures the end-product will be successfully tested.

    Dispensing
    Solder Paste Jetting: A Broadband Solution
    Recent product miniaturization breakthroughs have pushed stencil printing solder paste to its current process limits. Many different approaches can be taken to address this issue. A just-published study takes a step approach to understand the challenges associated with noncontact dispensing, better known as jetting, associated with both large-volume jetting and ultra-fine dot jetting.
    by Rita Mohanty, Ph.D.

    Component Qualification
    Acoustic Screening to Remove Suspect Plastic Components
    Most gap-type anomalies make no difference in the proper functioning or lifespan of the component. Some, though, depending on size and location within the package, can expand until they break a connection. A new technique to image the bulk of the mold compound in many sequential slices reveals the real dangers.

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.
