  • Process Improvement
    The DfM Continuum
    Design and manufacturing often are thought of as separate processes, with some interdependencies. But absent a feedback loop, development will be marred by unnecessary defects and re-spins.
    by John Isaac and Bruce Isbell

  • Signal Integrity
    Open 'Eyes' in the Frequency Domain
    Although final performance is measured in the time domain, a detour may be the faster route to a signal integrity solution.
    by Dr. Eric Bogatin

  • Screen Printing
    Divining Value in Screen Printer Ownership
    The purchase price of a capital item is only one element of value, but it can be one that is disproportionately influential in the purchase decision. A look at how some companies are matching equipment requirements with new ways to evaluate cost-of-ownership.
    by Trevor Warren

  • Screen Printing
    Why Mixed Signal Calls for Precise Stencils
    Stencil accuracy has a direct bearing on the correct thermal profile.
    by Zulki Khan

  • Materials Engineering
    Heat Transfer in LED Assembly
    LEDs may seem cool to the touch, but they all produce heat. So while they offer significant benefits over filament and fluorescent lighting, dissipating heat within an LED assembly involves the selection and use of thermally conductive and (usually) electrically insulating materials.
    by Chuck Neve

  • Service Excellence
    The Big Mack Attack
    For two years running, Mack Technologies has taken home top honors in Circuits Assembly's Service Excellence Awards. Its secret? A customer service strategy based on execution performance and using data, derived through open and honest communication with customers, to drive improvements in performance.
    by Mike Buetow



  • ROI
    Fixing process improvement.
    Peter Bigelow

  • Focus on Business
    Improve workers' lives, improve the bottom line.

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.

The Human Touch

For those who count on the electronics industry for big feats, it’s been a remarkable couple of years.



Advances in Concentration Monitoring and Closed-Loop Control

Contaminated bath water skews refractive index results. New technology can accurately measure aqueous cleaning agent concentration.

Circuits Disassembly: Materials Characterization and Failure Analysis

A systematic approach to nonconventional methods of encapsulant removal.
