Electrical Performance of an Organic, Z-interconnect, Flip-Chip Substrate

Oct 25, 2007 | Michael J. Rowlands, Rabindra Das.

More and more substrate designs require signals paths that can handle multi-gigahertz frequencies [1-3]. The challenges for organic substrates, in meeting these electrical requirements, include using high-speed, low-loss materials, manufacturing precise structures and making a reliable finished product. A new substrate technology is presented that addresses these challenges....

A Practical Guide to Achieving Lead-Free Electronics Assembly

Oct 18, 2007 | Karl Seelig, David Suraski

To successfully achieve lead-free electronics assembly, each participant in the manufacturing process, from purchasing to engineering to maintenance to Quality/Inspection, must have a solid understanding of the changes required of them. This pertains to considerations regarding design, components, PWBs, solder alloys, fluxe s, printing, reflow, wave soldering, rework, cleaning, equipment wear & tear and inspection....

Maximizing Process Control with Controlled Convection Rates

Oct 10, 2007 | Rob DiMatteo, Fred Dimock, Pierre LeMieux.

Process engineers, who are seeking to achieve the most effective and reproducible thermal transfer process, look to today's forced convection ovens for applications such as flipchip, BGA, and lead-free soldering. A forced convection process to maximize thermal uniformity can be best accomplished by employing static pressure generation in what's known as "closed loop convection"....

RF Packaging Advancements for Navy Applications

Oct 02, 2007 | Fred Verdi, EMPF Technical Director

The vast majority (99%) of the electronics market in North America is composed of products produced for commercial applications. The 1% share of the electronics market driven by Department of Defense (DoD) applications has created a niche market for RF qualified devices. The DoD, with its emphasis on COTS (Commercial Off The Shelf) and "Open" systems, is beginning to become more interested in using commercially oriented RF devices for military applications as a means to leverage the volumes and innovations of the commercial world....

The Pin-in-Paste (or AART) Process for Odd Form and Through Hole Printed Circuit Boards

Sep 27, 2007 | Jay B. Hinerman, DEK Inc; K. Srihari, Ph.D., Department of Systems Science and Industrial Engineering State University of New York; George R. Westby, Director - SMT Laboratory, Universal Instruments Corporation.

Considerable interest exists in the process known as the pinin- paste, or the Alternative Assembly and Reflow Technology (AART) process. The AART process allows for the simultaneous reflow of both odd-form and through hole devices as well as surface mount components. This process has several advantages over the typical mixed technology process sequence that includes wave soldering and/or hand soldering, often in addition to reflow soldering....

Laser Solder Reflow: A Process Solution Part II

Sep 13, 2007 | John Vivari; EFD, Inc., Alex Kasman, Leister Technologies USA

With the use of laser light for reflow having been established, all that remains is to apply it to best effect. Each time a laser is fired, it pumps a specific amount of energy at a particular wavelength to a particular point in space. Where technique comes in is choosing where and for how long to apply that light along with the application of accessory equipment to optimize solder paste reflow. This presentation covers the specifics of how to determine which process choices are the right process choices based on the needs of your product to maximize yield and throughput....

Laser Solder Reflow: A Process Solution Part I

Sep 06, 2007 | John Vivari; EFD, Inc., Alex Kasman, Leister Technologies USA

EFD Inc. and Leister USA have collaborated to bust the myth that you cannot perform laser reflow with solder paste. Using Leister diode lasers, EFD has formulated solder pastes that survive the rapid reflow cycle typical of laser heating. These solder pastes reflow and wet well, without spatter, even when heating is accomplished in less than half a second. The flux core in wire solders cannot boast such flux spatter resistance in such an aggressive heating environment....

Boundary Scan Skews Test Coverage Tradeoffs in your Favor

Aug 23, 2007 | Dominic Plunkett, Chief Technology Officer, XJTAG, Ltd.

The complexity and programmability of modern embedded boards means that knowledge built up during debugging and testing must be regarded as Intellectual Property (IP) and therefore preserved. But many of the processes and tools used today do not provide a means to preserve or pass on this IP, and thereby forego valuable opportunities to save time and improve quality during subsequent stages of product development....
