KIC (San Diego, CA), a provider of thermal process development and control software, will be a co-presenter at the Indium Lead-Free QuickStart Seminar on June 16 in Nuremburg, Germany. The company will present the topic, "How to Implement Lead-Free Assembly at Your Factory," with Indium Corp. and Motorola.

The lead-free implementation seminar is designed for manufacturing management to "QuickStart" the lead-free learning curve. It covers printed wiring board finishes, components, alloys and surface-mount technology processes. It also reviews an actual implementation of a lead-free process, performed by Motorola, that has been used to assemble more than five million cellular phones to date. The workshop will finish with a section on establishing individual lead-free implementation plans.

The agenda will include an introduction, overview and presentations by Dr. Ning-Cheng Lee of Indium Corp., Mr. Peru of ACB, Dr. Manfred Suppa of Peters, Angus Westwater of Rohm, Mary Beth Allen of KIC, Eddie Hernandez of Hewlett Packard, Gerjan Diepstraten of Vitronics-Soltec, Ross Berntson of Indium Corp., Hans-Juergen Albrecht of Siemens, Mark Krmpotich of Scientific Atlanta and Vahid Goudarzi of Motorola.

Seminar topics include: the state of lead-free legislation, marketing and worldwide implementation; the current alloy systems in use, and why and how they were chosen; which PWB finishes are preferred in lead-free assembly; concerns with components and the status of lead-free components in the industry; best practices for setting up stencil printing, placement, inspection, reflow and wave; the effect of lead-free manufacturing on the reflow process, achieving and maintaining the tight process window; how to perform designed experiments (DOE) to optimize the lead-free process; and how to establish a statistical process control program.

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.
