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.

FEINFOCUS (Stamford, CT), a manufacturer of x-ray inspection systems and tubes, and GOEPEL electronic (Jena, Germany), a vendor of electronic and optical test and inspection systems, have combined their 30 years of test and inspection experience with a recent technology partnership.
The new cooperation and development project has resulted in the launch of the OptiCon X-Line inspection system, which was unveiled at Productronica 2003. The new system combines automated optical inspection (AOI) and x-ray inspection technology for the automated analysis of hidden solder joints.
The system, based on the OptiCon series from GOEPEL, provides automatic recognition of shorts and solder bridges, as well as missing solder balls on ball grid array (BGA) and microBGA devices. FEINFOCUS contributed to the development of the system with x-ray tube technology that was implemented according to GOEPEL's specifications. The companies will publish joint technical papers and application findings through the use of the combined technologies.
