The practice of outsourcing electronics manufacturing gained popularity in the 1970s—largely in the U.S., and today most of the world's largest contract manufacturers (CMs) are headquartered in North America. Yet the never-ending search for lower cost manufacturing has prompted these companies to shift manufacturing to other regions—primarily to Asia. In fact, electronics manufacturing strategist Technology Forecasters Inc. (TFI, Alameda, CA) estimates that today more than a third of the world's outsourced electronic products are built in China and that by 2007 the portion will increase to half.

Profiling the type of manufacturing most likely to remain in North America is the focus of a study TFI will present at its March 10 Quarterly Forum for Electronics Manufacturing Outsourcing and Supply Chain, in the Dallas, TX, area. For the study, entitled Electronic Manufacturing Services Industry in North American Market: Current Outlook and Positioning for the Future, TFI interviewed executives at CMs around the world as well as name-brand product companies' outsourcing decision makers choosing among regions.

"Although most of the executives we interviewed were able to identify some niche markets or region-appropriate functions likely to remain in North America, without exception every executive predicted further loss of manufacturing jobs on the continent," said TFI president Pamela Gordon. "The keys to CMs retaining as many jobs as possible are to offer multinational manufacturing options—whether at their own facilities or through alliances—and to serving local customers with such close attention as to create a nearly impenetrable barrier to leave."

Yet even for the types of business likely to remain, disagreement exists among CMs and their customers regarding the staying power of manufacturing in North America. The CEO at a mid-sized North American CM said, "The strength will be the responsiveness of the industry in North America. This will not be available half way around the world. Cheaper product undelivered does not help the customer's bottom line."

A different response was offered by an outsourcing decision maker at a large North American customer company: "It's mainly price. Mexico, Dominican Republic and Puerto Rico have some cost advantages, but if total cost is less elsewhere then the product won't stay in North America."

Other TFI reports to be presented at the Quarterly Forum include Competing with the Dragon: The EMS Industry in Asia Outside China and Outsourcing in Telecom: Finding Value Again. A panel on the future of design services will be moderated by Tom Valliere of Design Chain Associates, and feature Bill Coker of Elcoteq Americas, Michael Shores of Texas Prototypes, Mike Wilkinson of Paragon Innovations and several original equipment manufacturers (OEMs) sharing their experiences of using contract design services. Also, Agile Software will coach Quarterly Forum members in tracking materials and recycling in accordance with environmental regulations WEEE and ROHS.

Aguila Technologies (San Marcos, CA) announced that Henkel-Loctite Corp. (Industry, CA) has purchased a license to Aguila's patents on a pre-applied flip chip underfill technology. The Aguila license provides Henkel-Loctite the right to provide wafer-applied flip chip underfill adhesives that will enable fabrication of flip chips at lower cost and increased yield by eliminating the conventional capillary underfill technique.

Aguila's work in the field of advanced flip chip packaging over the past few years has led to over a dozen patents ranging from wafer-level and flip chip processes to no-flow underfills. Aguila's invention provides for a two-portion, or two-level, fluxing adhesive underfill approach. It overcomes the problem of applying an underfill adhesive containing filler particles to a flip chip prior to assembly.

Conventional flip chip technology generally requires that flip chip assemblies be encapsulated with an adhesive, or underfill, to protect the tiny flip chip solder joints from thermal fatigue failure. Particulate fillers in conventional underfills are the essential ingredients that reduce the adhesive's expansion rate with temperature fluctuations. The reduced expansion allows the underfill to match the expansion of the chip's solder bumps, greatly reducing fatigue failures during thermal cycling.

However, the application of underfills to finished flip chip assemblies has historically been a limiting factor to production yield and assembly cost. Conventional underfills are applied through a capillary flow liquid dispensing operation that creates a number of production obstacles.

Ideally, underfills would be applied to flip chips prior assembly. Attempts to put the essential filler particles into no-flow underfills have generally resulted in poor solder wetting and reduced product yields. The filler particles interfere with the flip chip soldering operation. These problems have led to no-flow underfills with no filler particles, limiting their usefulness.

Aguila's two-portion pre-applied underfill eliminates the problem. One portion, constituting the majority of the underfill, is filled with the essential particles that reduce thermal expansion. A second portion comprises few or no filler particles. Yet, it is the second portion that provides the fluxing action during the flip chip soldering operation. This results in a pre-applied underfill that does not interfere adversely with the soldering operation.

Aguila's innovation provides two-portion underfills that are pre-applied to flip chips, either at the wafer level, after wafer sawing, or just prior to the assembly operation. Thus, it eliminates the tedious dispense operation after flip chips are assembled. The underfill may be applied to hundreds of chips at a single time at the wafer, instead of one at a time after assembly.

According to IPC (Northbrook, IL), the North American IMS/PCB Industry book-to-bill ratio for January remained positive 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 increased 28.4% from January 2003 and orders booked increased 19.8% year-on-year. The shipment index was 118.1, down 6.5% from December 2003 and the IMS/PCB booking index was 125.2, down 8.7% sequentially.

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.

Percentages based on the index numbers reflect changes in the size of the industry. Data reported by current participants in IPC's monthly survey, however, tell a different story. These participating companies report that their shipments increased 25.1 percent in January 2004 over January 2003, and that their orders booked increased 18.2 percent in January, year over year.

Together, these figures show a North American PCB industry that has contracted, but the companies that remain in the industry are doing better than last year.

The information in IPC's monthly industry statistics is based on data provided by PCB manufacturers that participate in IPC's monthly IMS Statistical Program. The companies reportedly represent 60% of the U.S. IMS industry.

UP Media Group Inc. (Atlanta, GA) has announced the details for two technology presentations that will take place at the 13th annual PCB Design Conference West (PCB West) on March 15-19 at the San Jose Convention Center in San Jose, CA.

To kick-off this year's conference, the PCB Technology Forum and Welcome Luncheon will take place on Monday, March 15, from 12-1:30 p.m. Joseph Fjelstad, co-founder of Silicon Valley startup SiliconPipe and author of An Engineer's Guide to Flexible Circuits, will make a technical presentation on "The Benefits of Three-Dimensional Partitioning of Printed Circuit Signal Routing."

According to Fjelstad, it is often assumed that copper is just too slow for electronics applications requiring high speeds; however, the truth is that copper can transmit signals at near the speed of light if properly configured. Fjelstad's presentation will focus on an innovative process being developed at SiliconPipe. This creative destruction involves splitting an integrated circuit (IC) package I/O by launching high-speed signals through the bottom of the package, while routing lower speed power and ground signals through the bottom of the package. Signal strength and integrity should be improved, and with the high-speed I/O more accessible, the IC can be tested with full parametrics at full speed.

Conference attendees taking one of six Professional Development courses taught on Monday, March 15, may attend the PCB Technology Forum and Welcome Luncheon for free. All others who wish to attend the event may do so for a fee of $25.

A second technology presentation will be held on Thursday, March 18, from 11: 15 a.m. to 12:15 p.m., and attendance is free to all registered conference and expo-only attendees. Eric Hills, the applications engineering manager at Endicott Interconnect Technologies, will make a technical presentation on "Meeting the PCB Needs for High-Speed Data Transmission."

According to Hills, achieving data rates of up to 10 Gb/s requires close attention to transmission line geometries, dielectric properties and via utilization, as well as a physical design awareness that is not usually required. His presentation will address the methods for ensuring that the interconnections are suitable for high speeds, and how to accomplish this with traditional (i.e., cost-effective) techniques that provide maximum wiring efficiency. Special focus will be placed on the advantages that certain transmission line and via structures provide for such high-speed connections.

Before founding SiliconPipe, Fjelstad was with Tessera, where he was the company's first fellow. He is the author, co-author or editor of several books and numerous articles on electronic manufacturing. Fjelstad is also a prodigious inventor, with more than 150 U.S. patents issued or pending.

Formerly the product manager for PCBs at EIT, Hills has held positions at IBM as applications engineering manager for ceramic packaging and as new products program manager for PCBs and electronic assemblies. He has a B.S. in chemical engineering from Penn State.

Three-Five Systems Inc. (TFS, Tempe, AZ), has hired key employees and acquired the customer base of Integrex Inc. (Bothell, WA), a privately-held electronics manufacturing services (EMS) company. TFS will immediately begin working with customers to transfer existing programs from Bothell to the Redmond facility; the process is expected to take approximately six weeks.

The agreement is the second EMS transaction by TFS in the Northwest in the past 15 months. TFS acquired the EMS company ETMA (Redmond, WA) in December 2002 and maintains operations in the Redmond location.

Integrex was founded in 1999 as a full-service EMS company providing turnkey manufacturing services, including design, new product introduction (NPI), printed circuit board assembly (PCBA), system integration, test and after-market support. Primary investors included Benaroya Capital, Fluke Venture Partners and Sunrise Capital. Representatives for the investor group indicated that several companies competed to obtain the Integrex business and TFS was selected because of its existing presence within the Northwest regional customer community, combined with strong offshore manufacturing capability and a solid balance sheet.

Jack Saltich, chief executive officer of TFS, said, "Integrex has penetrated certain market segments, including military applications, that represent target growth areas for TFS. We believe we can expand upon this business by leveraging our manufacturing quality in Redmond with our high volume efficiencies at our Asian manufacturing locations and thereby continue our initiative to become a dominant EMS provider in the Northwest."

TFS is buying the raw material inventory of Integrex as needed to begin manufacturing products for its new customers and is providing Integrex with an up-front, one-time payment to offset customer transfer costs. TFS is not acquiring Integrex's manufacturing facility in Bothell, and it is not expected that the transaction will generate a goodwill asset for TFS.
