MMX™ Technology Architecture Overview

Technical Library | 1999-05-07 10:20:34.0

Media (video, audio, graphics, communication) applications present a unique opportunity for performance boost via use of Single Instruction Multiple Data (SIMD) techniques. While several of the computeintensive parts of media applications benefit from SIMD techniques, a significant portion of the code still is best suited for general purpose instruction set architectures. MMX™ technology extends the Intel Architecture (IA), the industry's leading general purpose processor architecture, to provide the benefits of SIMD for media applications.

e-Supply Chain Management: Prerequisites To Success.

Technical Library | 2001-05-23 16:15:54.0

The supply chain is made up of all the activities that are required to deliver products to the customer - from designing product to receiving orders, procuring materials, marketing, manufacturing, logistics, customer service, receiving payment and so on. Anyone, anything, anywhere that influences a product’s time-to-market, price, quality, information exchange, delivery, among other activities is part of the supply chain.

Testing To Eliminate Reliability Defects From Electronic Packages

Technical Library | 2006-06-29 13:37:36.0

Electronic Packaging is a critical part of all electronic devices and can be a source of the reliability problems experienced by systems using those devices. In many cases, the packaging defects are intermittent in nature and difficult to detect. This paper describes a tester that has been used for 20 years on commercial products and has proven to be extremely effective in detecting these defects prior to component assembly.

Effects of Assebly Process Variables on Voiding at a Thermal Interface.

Technical Library | 2007-04-04 11:43:41.0

The present work offers a discussion and a first case study to identify and illustrate voiding mechanisms for a particular TIM between a heat spreader and the back of a flip chip. Pronounced differences were observed between stencil printing and dispensing in terms of initial void formation, apparently related to the specific properties of the material. Measurements of the effects of heat ramp rate and peak temperature showed the subsequent evolution and final void size distribution to be determined by the initial part of the cure profile up to the material gelling temperature.

Embedded Thermoelectric Cooling

Technical Library | 2008-03-25 18:15:54.0

Thin film thermoelectric devices offer a fundamentally new operating regime for integrated, active cooling solutions and localized thermal management, yet the assembly methodology used to implement these devices is fully compatible with existing surface mount approaches. In order to take advantage of these unique characteristics, thin film thermoelectric devices need to be designed for the appropriate thermal and form-factor environments, with system-level constraints carefully considered as an integral part of the overall design process.

Integrated Offset Placement in Electronics Assembly Equipment - The Answer for Solder Paste Misalignment

Technical Library | 2008-10-29 18:45:53.0

Growing demand for compact, multi-function electronics products has accelerated component miniaturization and high-density placement, creating new challenges for the electronics manufacturing industry. It is no longer adequate to simply place parts accurately per a pre-defined CAD assembly program because solder paste alignment errors are increasing for numerous reasons. The solution to this problem is a system in which the placement machine can automatically detect and compensate for misalignment of the solder paste to produce high-quality boards regardless of the process errors beforehand.

Controlling Copper Build Up in Automatic Soldering Equipment Using Lead-Free Solder

Technical Library | 2008-11-20 00:46:10.0

The Sn/Ag/Cu family of alloys is the leading candidate for a lead-free alternative. The first part of this study was to determine if there is any significant difference between Sn/Ag/Cu alloys when used in automatic soldering equipment in terms of copper build-up in the system. The study compared two Sn/Ag/Cu alloys to determine if at processing temperatures one alloy would absorb less copper than the other alloy.

Startling Results From Reliability Testing

Technical Library | 2009-03-13 00:27:09.0

Open product reliability testing in Stockholm, Sweden in January as part of a live production event generated some quite startling results. It was apparent that many components simply cannot handle the high reflow temperatures of a lead-free soldering process, and that many surface-mount machine suppliers are battling significant problems with QFN packages and other components that are mounting edgeways (bill boarding). However, some suppliers have achieved good results.

New Precision Coating Deposition Method for Photovoltaic Manufacturing

Technical Library | 2009-05-28 18:15:46.0

Considerable effort is ongoing to improve the efficiency and to move towards high-volume manufacturing of photovoltaic cells. Much attention has been focused on developing in-line processes to replace the current batch processes. A critical process to improve the performance of solar wafers is the application of Dopants. The basic requirement for this process is an automated method for applying a very thin, uniform film of Dopant to the silicon wafer as part of an in-line manufacturing process.

Determination of Copper Foil Surface Roughness from Micro-section Photographs

Technical Library | 2013-04-25 11:42:01.0

Specification and control of surface roughness of copper conductors within printed circuit boards (PCBs) are increasingly desirable in multi-GHz designs as a part of signal-integrity failure analysis on high-speed PCBs. The development of a quality-assurance method to verify the use of foils with specified roughness grade during the PCB manufacturing process is also important...
