December 2004 Engineering - Relays - Impact of Lead-Free Soldering on the Reliability of Relays
In recent years, environmental issues have become more and more important. Many materials and substances are forbidden for use in products and in manufacturing because they are toxic, ozone-killing, or problematical in some other respect.
November 2004 Engineer Sound Quality - Sound Quality Assessment and Labeling
The sound that a product makes can tell the user a lot about its quality and functionality. This information may be combined with other non-aural information, such as the product’s performance, design, color, or feel, to give some overall impression. Products that make annoying sounds are unlikely to be well-received, yet proper product sound assessment does not appear to be widely considered throughout the UK.
November 2004 Engineering Porcelain Enamel - A Novel Non-Stick Porcelain Enamel
To fulfill the industry’s long-held desire for a truly easy-to-clean surface, a new ceramic-based, non-stick coating for household and commercial cooking appliances has been developed that has excellent scratch, abrasion, and heat resistance, as well as superb cleanability.
May 2004 Engineering Microelectronics - New Insights in Underfill Flow and Flip Chip Reliability
During the last several years, Flip Chip Technology has been widely accepted as a means for maximum miniaturization of microelectronic assemblies. Flip Chips have been used in advanced products such as cellular phones, global positioning systems (GPS) devices, and in medical devices such as pacemakers.
January 2003 European Edition - APPLIANCE Engineer - Thermal Modeling of Oven Cooking and the "Brick" Test
This paper examines the performance of a domestic oven by developing a simple model to macroscopically describe the relative heat and mass transfer involved, followed by a closer look at the calculation of the thermal mass depending on food ingredients and mass loss due to evaporation.
