Cellular compound insulates radio cables

The increasingly higher operating frequency of 3G mobile phone antenna cables places ever-greater demands on the performance of insulation materials.

Big get bigger as Itel leads in semiconductor growth

Intel Corp in 2005 is expected to solidify its position as the world’s leading semiconductor supplier, posting the highest revenue growth among the top 10 chip makers for the year, according to a preliminary ranking from iSuppli Corp.

Managing PCB signal quality

Driven by advances in lithography, IC switching speeds continue their progressively-faster march. At the same time, escalating clock speeds result in much less forgiving timing margins

LCD-TV makers face tough times or revenue growth

Television makers look forward to strong unit sales growth over the holiday season, as consumers snap up increasingly low-priced LCD sets, according to analysts at iSuppli Corp.

Design for Manufacturing points the way to overcoming chip problems

Getting a good yield from the latest 90nm and 65nm silicon manufacturing processes is still a struggle, and leading edge designers looking at 45nm designers are seeing even more problems.

Modular approach helps specify design criteria for rugged enclosures

Pressures to reduce development time, costs and project risks have generated major interest in commercial off-the-shelf (COTS) approaches for defence applications. In place of defence-rated components and sub-assemblies, the search is on to achieve the same reliability and compliance using commercial equipment.

Photochemical milling cuts RFI screening cost

When a customer approached Photofabrication Services for a quote to produce RFI screening cans, the company found that changing the manufacturing process and specifying a RoHS-compliant finish enabled parts to be formed and spot-welding after plating, resulting in a substantial reduction in both cost and lead-time.

International event on lead-free electronics

IPC and Soldertec Global have announced the 4th International Conference on Lead-Free Electronics and Implementation of the RoHS Directive’ to be held in Copenhagen-Malmo, between April 25th–27th 2006.

Laser marking for board identification

Marking of PCBs and modules for traceability and warranty purposes is often a costly and time consuming activity, adding little or no value to the end product.

Viscosity control for conformal coating

Conformal coating applications present challenges to manufacturers. They must be applied with accuracy, repeatability and selectivity to increasingly smaller packages.

Communication complexity increases testing need

With considerable advancements in technologies such as asynchronous transfer mode (ATM), synchronous optical network (SONET), gigabit Ethernet (GbE) and 10gigabit Ethernet (10GbE), the European telecommunication industry is seeing accelerated growth.

Point-of-load dc/dc micromodule

Existing point-of-load dc/dc module regulators such as point-of-load power supplies are assembled on pcbs with leads for through-hole or surface mount placement on a system board.

DC-DC converts support 3:1 input voltage

Tyco Electronics Power Systems Inc has released its EQD075A and EQD020A0F series dc-dc converters, part of a new generation of open-frame dc-dc power modules designed for UMTS and CDMA base stations and wireless IP routers applications.

Ultracapacitor have power burst potential

Ultracapacitors, which can be thought of as intermediaries between batteries and conventional capacitors, have the potential to meet power burst needs in applications from portable electronics to automobiles.

Power supplies give advance warning of potential trouble

Kiyotaka Tomioka looks at power supplies that feature on-board troubleshooting; paramount to smart maintenance.

How to beat the heat generated by computer processors

In recent years, virtually no other technology has been as dynamic as the development of computer processors.

Cheaper and more robust touch screens

Body Content HereCharge-transfer capacitive touch company Quantum Research Group has unveiled a new technology called QField that uses the company’s charge-transfer sensing techniques to enable, for the first time, the design of capacitive touch screens with a single conductive layer of Indium Tin Oxide (ITO), rather than the two layers needed for resistive and other capacitive screens.

A robust but flexible approach to connectors

DDK has added a metal shell version to its range of DK series connectors.

High definition TV to make its mark

The world of video is seen as the next great challenge in the industry, and new players are coming through with come innovative architectures.

Soldering station for engineering, repair and lab services

The new WMRS soldering station from Weller, one of the brands of the American company Cooper Hand Tools, offers precision and speed. This is made possible by the digital control electronics and the small, lightweight soldering pencil which can reach 350°C in just seconds.
