The 13th annual PCB Design Conference West 2003, held March 15-19 at the San Jose Convention Center, received positive feedback from attendees and exhibitors alike regarding the five-day conference program of over 35 technical courses and the two-day product and service exhibition. The San Jose, CA-based venue, which is located in the heart of Silicon Valley, provided 1,482 attendees with an excellent setting for instruction, networking and face-to-face marketing opportunities.

"Trade shows and conferences in just about every market have been depressed in the last few years, so it is good to see that PCB design shows are following the same upward trend that we're beginning to see in other markets," said UP Media Group (UPMG, Atlanta, GA) president Pete Waddell. "We also are pleased that so many exhibitors have continued to include PCB West in marketing budgets that remain cautious and tight. Our exhibitors were enthusiastic about the quality of the attendee traffic on the show floor—to the extent that 72% of our 2004 exhibitors have already re-signed for 2005."

"DownStream Technologies decided to exhibit at PCB Design Conference West 2004 because the exhibition provides our company the most targeted access to the PCB design and manufacture professionals that we want to reach," said Rick Almeida, president of DownStream Technologies, an exhibitor. "We are very pleased with the leads that we were able to capture during the two-day exhibition and we've already re-signed for next year's show."

According to Waddell, PCB West conference attendees also were excited by the number and technical depth of courses taught during the five-day conference. Several special events were well attended and received praise from those who participated. These include the PCB Technology Forum and Welcome Luncheon, the Keynote Address by Mentor Graphics CEO Walden C. Rhines on "Breaking the PCB Design Process," the Opening Night Reception, the Pot O'Gold Party and Giveaway extravaganza and the PCB West Book Store, which featured participation by book publishers Prentice Hall and Wiley.

Dates for PCB West 2005 have been announced and the conference will be held March 7-11 at the Santa Clara Convention Center in Santa Clara, CA.

UPMG's next trade show is PCB Design Conference East 2004, which will be held Oct. 4-8 at the Radisson Hotel Manchester in Manchester, NH.

NEPCON Shanghai/Electronics Manufacturing Technology China (EMT China) will be held April 26-29 at the Shanghai Everbright Convention & Exhibition Centre. The Surface Mount Technology Association (SMTA) and the Electronics & Information Industry Sub-Council (CCPIT) of China are co-organizing the high-level surface-mount technology conference.

This year's program will consist of a keynote, technical sessions on lead-free technology and 0201 assembly and two half-day training courses on lead-free systems by industry expert and past SMTA president Dr. Jennie S. Hwang, H-Technologies Group Inc.

The Keynote and technical presentations will be given by the Ministry of Information Industry, Gartner Dataquest, Flextronics International, Indium Corp., ERSA, HITACHI, Kingston Technology Co., EKRA, Daiichi Jisugyo, Fuji, OK Interenational, Siemens Dematic and Solectron.

The first training course, Interconnection Technology and Printed Circuit Board (PCB) Surface Finish and Component Coating is intended to provide broad-based information that enhances technology foundation in preparation for lead-free implementation. The presentation will be comprised of two parts: the first will cover lead-free solder interconnections and the second will address the properties and performance of lead-free PCB surface finishes and the component lead coatings.

The second course, Manufacturing Implementation, will focus on achieving yield, quality and reliability. The course will examine the key process modules, including solder paste printing and reflow, and the system compatibility between the BGA/CSP solder sphere, assembly solder paste, component coating and PCB substrate surface finish.

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.
