Des Plaines, IL, Oct. 11 —  The next Lead-Free Technology Seminar presented by Kester, Metcal, BTU International and Soldering Technology Inc. (STI) will take place Nov. 9-10, 2004, in Atlanta, GA .

 

Designed to assist electronics assembly manufacturers with the implementation of lead-free assembly operations, the seminar covers Pb-free soldering in SMT, wave soldering, BGA profiling and rework. Successful case studies will also be discussed.

 

The seminar will help attendees develop a solid understanding of the process variables to maintain production yields and product reliability with Pb-free operations. Additional topics will include alloy selection, flux selection, wave process, SMT assembly, inspection and documentation, rework and hand soldering, reflow optimization and lead-free reliability.

 

Presenters include:

· Peter Biocca, senior market development engineer, Kester

· Paul Wood, market development manager, Metcal

·Fred Dimock, senior process engineer, BTU International

· Jason Gjesvold, analytical lab manager, STI.

SAN JOSE, Oct. 7 - With the glow of an outstanding 2004 still present, suppliers of silicon wafers are forecasting a marked slowdown in 2005.

According to the SEMI Silicon Manufacturers Group, wafer shipments will end 2004 up 23% year-on-year. But the group predicts wafer shipments will grow just 5% in 2005. The unit of measurement is millions of square inches.

"The silicon wafer capacity continued to be in balance with the demand through the first half of 2004 and we foresee continued moderate year-on-year growth that will result in cautious expansion and a tight supply scenario that should lead to an improved financial outlook for the silicon industry," said John Kauffmann, SMG chairman.

Kauffmann said that the SMG concurs with the statement in the July news release from the Japan Society of Newer Metals, which indicates that "the administrative circumstances of the silicon industry are becoming more severe [tight supply]" and "semiconductor manufacturers and silicon manufacturers should further strengthen ties of partnership and cooperate on technology, cost, etc. to settle the existing issues."

 

 

Process Rx: Kester Offers Pb-Free Clinic at Mexitronica

October 12— Kester will hold a Lead-free Mini-Clinic at their booth, number 710, during the  Mexitrónica Conference and Exhibition in Guadalajara, Mexico, from Oct. 19-21, 2004.

 

Users and future users of lead-free will have the opportunity to ask industry experts pertinent questions to enable them to achieve lead-free assembly rapidly and efficiently.

 

Kester will also exhibit a complete line of lead-free products. Kester University ‘s lead-free training program and consultancy services will also be available.

 

Armando Torres will host the clinic throughout show hours.

RESEARCH TRIANGLE PARK, NC, Oct. 11 -- MCNC Research & Development Institute will develop advanced interconnect technology for infrared detector systems to be used in in high performance military and space surveillance applications.

The U.S. Department of Defense awarded the nonprofit research group a research contract for the Vertically Interconnected Sensor Arrays (VISA) program. This contract is a collaborative effort between MCNC-RDI and DRS Infrared Technologies.

The program objective is to develop 3-D architectures and circuits that enable massively parallel signal processing for high-resolution IR focal plane arrays for strategic and tactical systems. The 3-D interconnect permits integration of  detector arrays with multiple layers of ICs by means of insulated and metallized vias (vertical holes) etched through the body of the IC chips. The resulting multilayer structure offers optimal short interconnect paths and enables significantly higher interlayer bandwidths for more demanding signal processing requirements.
