Cookson Electronics Assembly Materials (CEAM, Jersey City, NY) has introduced a new dulling flux technology, ALPHA EF-9301. The product is compatible with both tin/lead and lead-free processes and is designed to help manufacturers meet environmental regulations without sacrificing productivity.

Tested under real-world conditions, the flux was shown to deliver higher first pass yields, more throughputs and require less rework than competitors. It reduces bridging on connectors and bottom side components and provides superior hole filling. Additionally, it minimizes solderballing, significantly reducing board handling time. The flux creates smooth, fully dull solder joints, easing the visual inspection process. It is designed for both spray and foam applications, eliminating the need for investment in additional equipment.

CEAM has also announced the worldwide availability of ALPHA OM-338, an ultra fine lead-free solder paste. The no-clean solder paste is designed for a broad range of applications and is formulated to minimize the transition concerns from tin/lead to lead-free processes. It yields print capability performance across various board designs and is ideally suited for ultra fine feature and high throughput applications.

The paste provides voiding resistance and maximizes reflow yields across a range of thermal profiles. Full alloy coalescence can be achieved at circular dimensions as small as 0.25 mm. Use of the paste results in print consistency and rapid cycle times. It can be applied at print speeds of up to 200 mm/sec. The high performance of the solder paste increases plant efficiency, increases yield and reduces rework requirements. It meets the highest IPC voiding performance classification and is reliable, ensuring product longevity. The paste is halide-free and compatible with either nitrogen or air reflow processing.

CEAM has also introduced ALPHA Vaculoy SACX307 lead-free wave solder alloy, which will be available worldwide through Cookson's global distribution network. The alloy delivers high yield and fast throughput, while meeting the strict lead-free environmental mandates.

Its fast wetting speed delivers improved solderability, outperforming all Sn/Cu based alloys. It provides excellent drainage and minimizes bridging defects. The alloy creates strong, mechanically sound joints with long-term reliability. The solder minimizes dross generation, resulting in low process maintenance and reduced product waste.

The process window supports the use of a wide range of flux technologies.

CEAM, a Cookson Electronics company, develops, manufactures and sells materials used in the electronics assembly process. CEAM supplies a full line of solder paste, stencils, squeegee blades, stencil and printed circuit board (PCB) cleaners, bar solder, cored wire solder, wave soldering fluxes and surface-mount device adhesives.

Cookson Electronics Assembly Materials (Jersey City, NJ) is launching a new ALPHA Cored Wire product series using Cookson's manufacturing methods to create consistent flux cores, assuring repeatability with a Cpk rating of 1.826. Available in 10 tin-lead and lead-free alloys, the new cored wire complies with J-STD-004, IPC-SF 818 and ISO 12224 and is offered in the following ALPHA brands: SMT Plus, Reliacore 15, Telecore Plus, Cleanline 7000, Energized Plus and Pure Core.

Cookson Electronics developed a layer winding process that ensures consistent smooth pay-out for manual and automatic solder rework. In addition, special attention was paid to packaging the new core wire line. New color-coded spools make identification of the flux chemistry easy, and thick flanges help reduce the risk of wire damage during transit. New color-coded labels also assist with product identification by flux type and alloy, and shrink-wrapping of the spools keeps the wire shiny and clean in transit and during storage.

Cookson EAM, a Cookson Electronics company, supplies a full line of solder paste, stencils, squeegee blades, stencil and printed circuit board cleaners, bar solder, cored wire solder, wave soldering fluxes and surface-mount device adhesives.

The National Electronics Manufacturing Initiative (NEMI, Herndon, VA), an industry-led consortium focused on strengthening the global electronics manufacturing supply chain, is celebrating the tenth anniversary of its electronics manufacturing roadmap with a special banquet the evening of June 22 at NEMI headquarters. Featured speakers are Mauro Walker, chairman emeritus of NEMI, speaking on the NEMI legacy, and Dr. Iwona Turlik, corporate vice president for Motorola and director of the company's Physical Realization Research Center, who will discuss innovation through nanotechnology.

Walker was instrumental in the organization of NEMI and served as the consortium's founding chairman. He retired from Motorola in 1998, where he was senior vice president and director of manufacturing. Walker has had a long career of accomplishment in the advancement of electronic manufacturing and manufacturing technology in industry, academia and professional societies. He has testified before the U.S. Congress on the topic of U.S. manufacturing competitiveness. He is a recipient of the Institute of Electrical and Electronic Engineers' (IEEE's) Special Manufacturing Technology Award and the Society for Manufacturing Engineers' (SME's) Total Excellence in Electronic Manufacturing Award. Walker is an IEEE fellow and founder of the IEEE International Manufacturing Technology Symposium. He was instrumental in the formation of the MIT Leaders for Manufacturing program as well the Georgia Tech and University of Illinois Manufacturing Research Centers.

Turlik has worked in the electronics industry and academia for more than two decades. She has been with Motorola since 1994 and was previously director of Motorola's Corporate Manufacturing Research Center. Turlik received her M.S. degree in electrical engineering and her Ph.D. in technical science from the Technical University of Wroclaw, Poland, where she started her professional career as a tenured faculty member. She has worked with Bell Northern Research and MCNC and was a tenured professor with the Electrical Engineering Department, University of North Carolina at Charlotte. She was named one of the 10 most influential people in the printed circuit board (PCB) industry by PC FAB magazine and ATOMIC29 (2001-2002), and is an IEEE fellow. Turlik is a member of the NEMI board of directors and serves on the advisory boards of several colleges and universities.

The first roadmap, published in December 1994, was spearheaded by Walker and Lance Glasser, then director of the Electronics Technology Office at the Defense Advanced Research Projects Agency (DARPA). These two individuals helped organize the National Electronics Manufacturing Framework Committee to study the challenges facing the nation in electronics manufacturing and to develop technology roadmaps and policy options with which to address these challenges. The resulting roadmap was published by the American Electronics Association (now AeA) and the Electronic Industries Association (EIA, now the Electronic Industries Alliance). NEMI was incorporated the following year (1995), and the consortium has published a roadmap every other year since 1994.

The tenth anniversary banquet begins with a reception at 5:30 p.m. followed by dinner at 6:30. The roadmap workshop, which will review year-to-date progress on the 2004 NEMI Roadmap and solicit feedback and input from workshop participants, is scheduled for Wednesday, June 23.
