Agilent Technologies Inc. (Palo Alto, CA) has introduced its Versatest series Model V5400 to deliver a low cost of test across a full spectrum of memory devices. According to the company, the model's algorithmic pattern generator (APG) and patented tester-per-site (TPS) architecture provide configuration flexibility and up to four times improvement over existing systems in throughput for wafer sort and final memory testing.
Compatible with Agilent's model V4400, the newer version overcomes the challenge of testing standard and stacked memory modules such as flash, DRAM and SRAM while offering up to 4,608 channels and 144 independent test sites. The increased performance and lower system costs helps reduce the overall cost of test for semiconductor contract manufacturers, fabless design houses and memory integrated device manufacturers.
The growing consumer demand for digital devices with added functionality and smaller footprints at lower prices has given rise to new test challenges. The devices require higher frequency test systems and the flexibility to test multiple types of memory such as flash and DRAM concurrently, while continuing to require a lower cost of test. Agilent's single, scalable platform architecture will allow users to test standard memories, reduced pin-count devices, BIST-enabled devices and stacked memories.
Agilent's TPS architecture makes it possible for each device under test (DUT) to receive its own set of tester resources. The APG on the test site module has the ability to maximize tester resources based on the needs of the DUT. Dynamic APG can independently test up to four low-pin-count DUTs per site module. For complex tests or high pin count devices, APG can reallocate all site module resources toward testing a single DUT. Configurable solely through software, the APG enables the model to test devices without a change in tester hardware.

LPKF Laser & Electronics (Wilsonville, OR) has announced the new MicroCut II, a high-performance stencil laser with a high-resolution scanner. The laser is capable of cutting any shape, including square apertures with rounded corners, at up to 50,000 apertures per hour. This translates to a cutting speed of 11 openings per second.
The high cutting speed is accomplished by a specially-developed system that reduces mechanical movement by moving the laser beam completely independent from the x/y table.
The stencil laser has an aperture resolution of 12.5 nm. It can cut apertures as small as 30 µm and its effective material focus diameter of 20 µm produces sharp contours.
The stencil laser features proprietary PulseShape technology, which eliminates the heat effect that causes coining or warpage of high-density and thin stencils. As a result, no external coolant is required. The system also incorporates new technology that avoids burrs at exiting edges, so no post-treatment is necessary.
System software for laser is optimized for stencil production, processing 500,000 pads in a few minutes.

UP Media Group Inc. (UPMG) has announced the promotion of Andy Shaughnessy to the position of editor of Printed Circuit Design & Manufacture, the premier trade magazine serving the printed circuit board (PCB) design and manufacture markets. Shaughnessy will take the magazine's helm on July 16, the same day that current PCD&M Editor-in-Chief Mike Buetow will replace Lisa Hamburg Bastin as editor-in-chief of UPMG's Circuits Assembly magazine. Hamburg Bastin has resigned to take a position outside the electronics assembly industry.
Shaughnessy, who is currently Conference Chair for the PCB Design Conferences in addition to being associate editor of PCD&M, joined the magazine (then known as Printed Circuit Design) in 1999 as assistant editor. He has been writing and editing for daily newspapers and trade magazines since 1992, including serving as a crime reporter for a metro Atlanta daily newspaper prior to joining Printed Circuit Design. In addition to PCD&M, Shaughnessy's articles have been published in PC FAB, Circuits Assembly and EE Times.
"I am very excited about the opportunity to serve as editor of Printed Circuit Design & Manufacture. My main goal will be to continue providing the most up-to-date technical information to PCB designers, design engineers and fabricators," said Shaughnessy, who will work closely with UPMG Publisher Pete Waddell to ensure that PCD&M continues to capitalize on an improving electronics design and manufacture landscape.
"Fortunately, Mike Buetow is leaving PCD&M in great shape. With his background and knowledge of PCB assembly issues, Mike is the perfect choice for editor of Circuits Assembly. I look forward to working with Mike in the future," stated Shaughnessy.
"I have every confidence in Mike and Andy," said UPMG Publisher Pete Waddell. "They have both proven very skillful at taking the pulse of the markets we serve, not only reporting on these markets, but providing a leadership role as well. Our culture at UP Media Group has always been to promote from within when the situation presents itself and seems logical. With Mike replacing Lisa as editor-in-chief of Circuits Assembly and Andy being promoted to editor at PCD&M, we're putting that internal policy to the best use."
Buetow has more than 13 years of experience in the electronics industry, including six years at electronics trade association IPC and editorial positions at SMT Magazine. Hamburg Bastin led Circuits Assembly for over six years as editor-in-chief. She leaves to become editor of the National Maritime Center's publications branch. The Arlington, VA-based NMC is a Coast Guard Headquarters field unit established to promote marine safety, environmental protection and security.
