TEMPE, AZ – The manufacturing sector grew for the 26th straight month in July as the slowdown in May is looking more like a blip than a trend. New orders and production both saw higher rates of growth, according to the latest Institute for Supply Management (ism.ws) poll.

TORONTO -- Celestica Inc., a top tier electronics manufacturing services provider, today announced that it has acquired Ramnish Electronics, an EMS provider located in Hyderabad, India. Celestica will relocate and expand the company's operations in Hyderabad area later this year.

Terms were not disclosed.

VANCOUVER -- Nam Tai Electronics reported second-quarter net income of $6 million on sales of $185 million, a company record for quarterly sales.

For the June quarter, the EMS provider's sales were up 25.5% year-over-year, while net income fell 92.8%. In Q2 2004, the company received a one-time gain of $71 million from the IPO of one of its subsidiaries. Gross profit was up 7% to $23.8 million.

BEIJING -- A merger of several of state-owned electronics firms will create the nation's largest electronics concern, various news outlets reported today.

China Electronics Corp. and China Great Wall Computer Group are among more than a half-dozen firms that will merge into the new comglomerate. The group received government approval earlier this week.

TORONTO – In its second acquisition in as many days, Celestica has bought CoreSim, a provider of design analysis and redesign services. The move will strengthen Celestica’s design services by adding intellectual property in the form of unique engineering tools and processes.

Rochester, NY– EMA Design Automation and AEi Systems have released the Power IC Model Library. The PSpice library incorporates over 150 time-domain simulation models for power electronic designs and gives designers the ability to plug in a model, representative of the actual IC, and simulate the switching performance under actual operating conditions.

“Many EDA vendors only have access to information in the data sheets, which is not sufficient when modeling a controller or regulator,” said Charles Hymowitz, managing director of AEi. “The data sheets simply do not have the level of detail required, and companies who rely solely on data sheet input produce substandard and inaccurate models.”

The models in this library enable designers to perform high-speed, cycle-by-cycle simulations to show true large-signal performance, simulate current-mode control using accurate modeling techniques, run CCM and DCM converter simulations, generate line and load step responses, and measure power stage loss and stress analysis for all major components.

The models are compared and verified with bench data under startup, steady state, line, and load transient conditions. Nonlinear characteristics such as propagation delay, switching speed, drive capability, maximum duty cycle/current limits and startup phenomena are all accurately modeled. Designers can directly compare the performance of components from various vendors and analyze the effects of different implementations such as peak current mode control, hysteric current control, low voltage and low operating current.
