  • 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.

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.
