CAMBRIDGE, MA -- A graphene-based chip could permit much higher speeds than silicon components, MIT researchers said.

TOKYO – Japanese electronics shipments fell 14.6% year-over-year in February to $1.95 billion, the Japan Electronics and Information Technology Industries Association said.

FREIBURG, GERMANY – A pair of firms hired by the European Commission to review existing and new requests for exemptions to the RoHS Directive today said it found seven unworthy of continuing.

Following a review of 29 exemptions, Okö Institute and Fraunhofer IZM have recommended seven not be continued: lead in linear incandescent lamps (Exemption 16); lead as activator in the fluorescent power of discharge lamps (Exemption 18); lead with PbBiSn-Hg and PbBiSn-Hg in specific compositions (Exemption 19); lead in oxide glass used for bonding front and rear substrates of flat fluorescent lamps used for LCDs (Exemption 20); lead oxide in the glass envelope of black light blue; lead alloys as solder for tranducers used in high-powered loudspeakers (Exemption 27), and hexavalent chromium in corrosion preventive coatings (Exemption 28).

The consultants were hired by the European Commission, which charged them with providing clearer wording of existing exemptions. The proposed new wording can be in the executive summary of the firm's report.

Okö also evaluated five requests for new exemptions: 1) lead in solders for the connection of very thin enameled wires with a terminal; 2) lead and cadmium as components of the glazes and color used to glaze or decorate lamp bases, lamp carriers or clocks; 3) lead in solders in a third-party component of cortex family equipment; 4) cadmium for use in solid-state illumination and display systems; 5) lead in solders for the connection of very thin (<100 µm) enameled copper wires and for the connection of enameled clad aluminum wires with a copper layer smaller than 20 µm.

The firms recommended granting number 4, refusing number 3, and were unable to make recommendations regarding numbers 1, 2 and 5.

Specific applications that do not have technically feasible alternatives, or cannot be foreseen within the next five to ten years, have been given an expiration date of July 31, 2014, which is when the next revision cycle will occur.

The EC will review the recommendations but have not set a timeline for release of its conclusions.

WASHINGTON, DC – The National Association of Manufacturers issued a curt response to a Chinese official’s view that countries consuming manufactured goods should be responsible for the emissions caused by their manufacture.

The unnamed official said the onus for emissions should be on consumers, not the countries that actually produced them.

In response, NAM executive vice president Jay Timmons said, in a statement, “It’s called ‘global warming,’ not ‘American warming,’ for a reason. Clearly, the producers of the emissions are the only ones that can take the steps and apply the technologies that will actually result in emissions reductions.

“The global environment and economy will not benefit if major stakeholder countries take pollution-reducing actions that drive up their costs while others do not. Such a situation risks merely reducing production in the countries taking action and shifting to higher-pollution production in countries that take little or no action, a scenario that results in economic harm to the US and no reduction in emissions.”

NAM supports the rules-based trading system, and welcomes that the recently released Obama Administration trade policy affirms this, Timmons said. The US “should take no actions that would violate its international obligations or trigger a debilitating trade war. Others need to affirm the same. “Any measures to address global climate change must involve the US and China working together for a realistic solution that does not threaten our national security and impose unbearable economic costs.”

ROGERSTONE, SOUTH WALES -- TT Electronics may lay off as many as 80 workers here, according to published reports.

The EMS company reportedly warned workers at the Tregwilym Industrial Estate site that layoffs could begin in a month if the market conditions do not improve.

SMYRNA, GA -- No, your eyes aren't deceiving you: CIRCUITS ASSEMBLY has redesigned its website.

The new design takes into account the best research on website design, readability and navigability. New additions include easy translations into nearly three dozen languages, to accommodate our large numbers of overseas subscribers and readers. We've moved the latest announcements of new equipment and materials to the front, to better draw attention to a very popular part of our site. Same with our columnists and features: these will rotate each month right on the home page. (The current issue and archives are still available, of course.)

SAN JOSE – The 90-day moving average for semiconductor equipment orders from North America-based manufacturers was $263.5 million in February, down 78% from last year, the SEMI trade group said. The bookings figures were the lowest since 1991.

PALO ALTO, CA -- Agilent Technologies has issued an application note describing improved methods for measuring distortion in broadband devices.

In a statement, the company said the paper illustrates the importance of characterizing broadband commercial and defense systems for linearity. The information focuses on the tests used to determine the level of a system's distortion and how they relate to Intermodulation Distortion and Intermodulation Distortion Noise. It summarizes with the test methods and the instruments used.

SMYRNA, GA – PCB East returns this year to the greater Boston area as the premier annual East Coast conference and exhibition for PCB engineers, designers, fabricators and managers.

PCB East will be held Apr. 27 - May 1 in Waltham, MA at the Westin Waltham-Boston.

More than 30 technical courses will be offered at the 14th annual PCB East, along with Free Wednesday, a day of one-hour technical sessions and events free to all attendees.

Other highlights of the conference include several new speakers and the premiere of an Evening with Industry Experts.

The conference will be accompanied by a free one-day tabletop exhibition on Apr. 29.

This show is produced by UP Media Group, parent company of Circuits Assembly and Printed Circuit Design & Fab.

SANTA CLARA, CA – Agilent Technologies has integrated Aster’s TestWay Coverage Analyst across Agilent’s PCB assembly test platforms.

TCA is a push-button test coverage analysis tool for coverage estimation (pretest program development) and coverage measurement (post-test program measurement) using PCOLA-SOQ1. It calculates theoretical coverage using CAD files and measures real coverage from the developed test programs.

The tool has been added to Agilents Medalist i3070 & i1000 platforms and other test and inspection equipment.

No financial terms of the agreement were disclosed.
