Bumping helps in high-speed, high-power applications that need quick turn to validate design, and helps provide better test simulation prior to final design. When cycle time is important, cost is critical and resources are limited, bumping a few die at a time can be effective to evaluate a design.
The process is applicable to traditional or MEMS components, and bumps can be applied to a substrate or die. Bump-to-bump variability is reportedly reduced compared to other processes such as solder jetting, screen-printing or electroplating. The traditional prototype method of using gold studs followed by thermocompression or thermosonic bonding can be eliminated.
The company can also attach solder balls to bare Al bond pads. The same hardware can be used to bump a die with various alloys to evaluate lead-free solutions. Alternating pads on the die can be bumped with differing alloys or geometry, allowing electromigration studies within the same die or within one wafer. This also reduces lot-to-lot and wafer-to-wafer variation.
The process is said to eliminate variables such as paste viscosity, metal load changes, missing bumps, voiding, and changes in size and planarity.
CVI can accommodate individual die bumping, partial wafer bumping, or die repair with various alloy compositions. Contact Terence Collier for more information: tqcollier@covinc.com.
Action Circuits services large component distributors, key names in the automotive industry and is the only approved programming center for Quicklogic Corp., Xilinx Inc. and Altera Corp. in Europe. The Luton, England-based company expects to program over 12 million devices this year.
The company's High Performance Circuits facility was named a member of the EPA's National Environmental Performance Track program, joining more than 300 facilities nationwide in their commitment to consistently exceed environmental regulation requirements. Teradyne is among only six companies in New Hampshire to be selected, the company said.
The National Environmental Performance Track program is designed to recognize and encourage top environmental performers -- those that go beyond compliance with regulatory requirements to attain levels of environmental performance and management that benefit people, communities and the environment, the company said in a statement.
The Teradyne plant qualified for the program through its performance, continuous commitment to environmental compliance and implementation of a strong environmental management system.
"Performance Track facilities represent a new generation of environmental leaders who have the vision to embrace the strategies that will protect the environment for generations to come," said Dan Fiorino, director of EPA's Performance Incentives Division.
COLLEGE PARK, MD - DfR Solutions and Interface Sciences Corp. have begun a joint investigation into potential improvements in CAF resistance through the application of ISC's molecular assembly and deposition technologies.
DfR Solutions, which has extensive experience in CAF experimentation and failure analysis, has identified this technology as a critical link in ensuring CAF robustness in high-density printed boards subjected to Pb-free reflow. The ISC process increases the uniformity and surface density of silane coupling agents on glass reinforcement - up to four times denser - compared with current technology, the companies said in a joint statement. This is expected to improve the intrinsic resistance of the fiber/epoxy bond to hydrolysis and cracking (during drilling), decreasing the influence of manufacturing defects on CAF. In addition, the process enables the deposition of novel surface chemistries that are expected to suppress filament formation. Substantial increases in CAF resistance are expected from the combination of these effects.
DFR and
Interface are currently establishing supply chain development channels with
glass, laminate and PCB manufacturing companies.
Accutronix is a privately-held electronics manufacturer with 47 employees in Owingsville, KY.
Mark Fulks, senior vice president at Key, becomes general manager for the Kentucky operation.
Key employs about 100 workers at its New Albany factory, and is constructing a 104,000 sq. ft. office and manufacturing facility in Jeffersonville, IN. The new plant is scheduled to be opened this summer.
The fourth-quarter net loss narrowed but sales declined sharply. Revenue and earnings were hurt by an unanticipated volume decline from a major customer that operates in a cyclical sector, the company said.
For the year the company generated $5.1 million in cash from operations. down from $5.5 million for 2003.
In a press release, John Caldwell, president and chief executive, said, "We expect to produce sequential revenue growth by the second quarter of 2005 and continue with positive momentum through the back half of the year."
For the fourth quarter the company reported a net loss of
$2.5 million on sales of $48 million. SMTC took $700,000 in restructuring
and other one-time charges. SMTC lost $2.6 million on revenue of $76.9 million a year ago.
