    Impact of Mesh Size and Stencil Technology on Deposition Volume
    A study on the impact on solder volume deposition using Type 3, Type 4 and Type 5 SAC 305 alloy powder in combination with stainless steel laser cut, electroformed and the emerging laser cut nano-coated stencils found that paste chemistry and rheology have a more profound effect on release than previously thought.

    Practical Thermal Profile Expectations in a Dual-Lane, Dual-Speed Reflow Oven
    Now that we have the ability to run different speeds in each lane, recipes must be devised that satisfy both boards. Here, we discuss methods for obtaining such recipes.

    Automated Solder Paste Inspection: A New Look at Stencils
    Many assemblers have foisted responsibility for automated inspection and verification onto the stencil vendors, referring to them as “qualified” or “certified” suppliers. In essence, they have placed the fox in charge of the henhouse on a portion of their most critical SMT process. While this practice might look good on paper, it’s rife with potential to backfire and ultimately cost more money than it saves.

    EMS Top 50
    The Great Rebound of 2010
    The electronics manufacturing industry will remember 2010 for many reasons: rampant component shortages (and the rise of counterfeits), the tight financial markets and tense end-market conditions. But mostly, it will be remembered for recovery.

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.
