The National Electronics Manufacturing Initiative (NEMI, Herndon, VA) has issued a set of interim recommendations for lead-free component finishes to be used in high-reliability electronic applications to minimize the risk of failures caused by tin whiskers. These recommendations were developed by the consortium's Tin Whisker User Group, comprised of nine large manufacturers of high-reliability electronic assemblies that annually purchase millions of dollars of components.
The group was organized to define methods and tests that would minimize the probability of tin whiskers creating functional or reliability problems in their products. Members include Alcatel, Celestica, Cisco Systems, Delphi Electronics, HP, IBM, Lucent Technologies, Sun Microsystems and Tyco Electronics. The group consensus is that pure tin electroplating presents a risk in high-reliability applications, and they have outlined cost-effective alternatives—using known mitigation practices and some level of testing—to minimize this risk.
This second interim report updates a report published by the group in June 2003 and presents recommendations for lead-free finishes for a variety of applications. These recommendations reflect the best judgment of the group members, based on their own experiences and the available data. The document outlines specific whisker mitigation guidelines supported by the group.
The document also discusses specific component types, assessing the reliability risk of tin whiskers for each and the various mitigation strategies recommended. The group is currently in the process of extending this work to create a user acceptance specification based on the test methods defined by the NEMI Tin Whisker Accelerated Test Project.
The Tin Whisker User Group's recommendations are available at: http://www.nemi.org/projects/ese/tin_whisker_usergroup.html.

According to IPC (Northbrook, IL), the North American interconnect manufacturing services (IMS)/ printed circuit board (PCB) industry book-to-bill ratio for February remained firm at 1.08. The ratio is calculated by averaging the index numbers for orders booked over the past three months and dividing by the average index numbers for sales billed during the same period. A ratio of more than 1.00 suggests that current demand is ahead of supply, which indicates probable near-term growth.
Shipments in February increased 27.5% year-on-year, while orders booked increased 42%. Shipments of PCBs are up 27.9% year-to-date, with bookings up 30.9%.
The February shipment index was 131.4, up 11.3% from January, and the booking index was 144.4, up 15.3%..
The index shows how current PCB shipments and bookings relate to an index point. In this case, 1992 was chosen as the index point because it was a stable growth year for U.S. PCB manufacturers. A shipment index number of 117.0, for example, indicates that shipments are 17% higher than average shipments for the same time period in 1992.
Survey participants report shipments have increased 28.6% year-to date and bookings have increased 33.6%.
The information in IPC's monthly industry statistics is based on data provided by PCB manufacturers that participate in the IMS Statistical Program. These companies represent approximately 60% of the U.S. IMS industry.

phoenix|x-ray Systems + Services Inc. (Camarillo, CA) has introduced the nanome|x, a high-powered nanofocus four-in-one failure analysis system. The x-ray inspection and failure analysis system can perform sophisticated nondestructive testing processes and resolve minute details. The system is designed to meet manufacturers' requirements of complex semiconductor devices and highly integrated electronic assemblies, yet can be used in the field of micromechanics and material testing as well.
The design is a result of a close partnership with its customers across several fields of applications. As a result, the system uses a high-powered nanofocus tube that can be operated in four modes covering the range from nanometer resolution to high-power radiation. Users can resolve an extreme level of detail (200-300 nm or 0.2-0.3 microns), displaying the slightest defect in miniaturized assemblies, such as pad wetting failures in flip chip solder joints or cracks in bond wires with verifiable results.
The same tube is infinitely variable up to 160kV and can also power up to 50W to see through highly absorbent materials like tungsten alloys used in IC packages or injector nozzles or microelectromechanical systems (MEMS).
The system deploys the company's ovhm|module technology that, without rotation of the board and thus loss of magnification in the oblique, allows for a high magnification (2000x) and 3-D-like imagery with 2-D magnification acquisition speeds. The tube and detector rotate up to 70° around the sample while providing the needed oblique view necessary to see minute defects in small solder joints found in fine-pitch ball grid arrays (FBGAs), microBGAs, column-grid arrays (CGAs), chip-scale packages (CSPs) and flip chips. This option is ideal for determining z-position solder voids, inspecting wetting quality, detecting cracks in bond wires, inspecting BGA device joint stacks and ball bond quality and measurement of via plating in both IC and printed circuit board (PCB) production.
The intensifier in the system is a digital detector technology and video system that delivers distinct images in pseudo real-time of poor absorbing materials with enhanced contrast.
Additional features include the automated inspection of BGA and quad flat pack (QFP) solder joints by an algorithm for the automated pad wetting analysis, software for the automated backend, software for the automated die-attach voiding calculation following user-defined standards and an ergonomic design for comfortable operation.

The National Electronics Manufacturing Initiative (NEMI, Herndon, VA), an industry-led consortium focused on strengthening the global electronics supply chain, and the IEEE Components, Packaging and Manufacturing Technology Society (CPMT, Piscataway, NJ) have entered into a formal agreement that outlines key areas of collaboration between the two organizations.
One of the primary collaborations under this new agreement will be roadmap development, beginning with the 2004 NEMI roadmap. The roadmaps, created every two years, map the future manufacturing needs of the electronics industry to identify the key technology and infrastructure developments required to assure leadership of the global supply chain over the next decade. It helps companies anticipate shifts in product requirements and provides an early warning of changes in technology or infrastructure.
The CPMT Society's members are technical professionals whose fields of expertise complement and substantially overlap with NEMI, and many CPMT Society members have represented their respective employers in the development of previous NEMI roadmaps. With more than 40% of the Society's members outside the U.S., the CPMT Society is committing experienced professionals from Europe, Asia and North America to many of the NEMI roadmap chapter committees.
Involvement of this broad-based group will help NEMI in its efforts to globalize the scope of the 2004 roadmap. Other areas of collaboration include NEMI involvement in CPMT Society-sponsored conferences, workshops and refereed publications, and CPMT Society coordination with the NEMI Technical Committee on development of research and development priorities.
"We have worked informally with the CPMT Society for many years, but wanted to form a more structured relationship with planned activities that would allow us to work together rather than just doing things on an opportunistic basis," said Jim McElroy, executive director and chief executive officer of NEMI.
Rolf Aschenbrenner, vice president of technical activities for the CPMT Society, said, "We also look forward to NEMI members presenting their work at CPMT Society workshops and conferences as well as soliciting papers for IEEE CPMT Transactions journals. In fact, we are already coordinating a NEMI tin whisker workshop as part of our Electronic Components and Technology Conference (ECTC) in Las Vegas this June."

Indium Corp. (Binghamton, NY) now offers flux-coated solder preforms to support the optimization of electronic assembly processes.
According to the company, flux-coated solder preforms offer several advantages over plain solder preforms, including: improved process time—using the pre-applied, fused flux, the preforms eliminate the need to add flux as an additional process step—and improved accuracy since the process fuses precise amounts of flux onto each solder preform. The system also reduces variability by eliminating process steps and by improving the consistency and accuracy of the flux quantity.
Flux coatings are available in no-clean formulations and the solder preforms are produced in a large range of sizes and shapes, to precisely suit each requirement.
Indium Corp. is a supplier of electronics assembly materials, including solder pastes, solder preforms, fluxes, lead-free solder alloys, underfill materials and die-attach materials. The company is also a supplier of commercial grade and high-purity indium.

Advanced Circuits (Aurora, CO), a quick-turn printed circuit board (PCB) manufacturer with real-time customer service, again experienced record growth in a down economy and an industry that has been declining for several years.
Although the PCB industry in the U.S. shrank 40% from 2001 through 2003, Advanced Circuits grew more than 15% each year during that time. Exceeding its goals for 2003, the company ended the year with more than $27.5 million in revenues.
"At a time when the U.S. PCB market is losing business to manufacturers overseas, we created a niche for ourselves in the prototype PCB market when we developed a system for building small quantity, quick-turn prototypes with a low premium price," said Ron Huston, president and chief executive officer of Advanced Circuits.
The company invested more than $5 million in capital into equipment and facilities in 2003, including a 62,000 sq. ft. office and manufacturing facility. Investments have already been planned for $500,000 worth of additional equipment in 2004. The company added 15 employees in 2003, bringing its total to 195, which includes three shifts in production and multiple shifts in other departments.
Advanced Circuits has gained an average of more than 200 new customers a month for the past three years. The company attributes its tremendous growth and customer retention to reliability and the customer-focused attitude of the entire staff. To time-pressed design engineers, the fact that Advanced Circuits delivers more than 99% of their boards on time or early is a significant quality in a manufacturer.
To ensure that this growth continues in years to come, a full-time professional marketing and training staff have been added to the Advanced Circuits team. Huston is also showing appreciation to the employees that made this success possible by treating the entire staff to an all-expense paid trip to Las Vegas, NV, over Memorial Day weekend.
