IPC — Association Connecting Electronics Industries® announced today the June findings from its monthly North American Printed Circuit Board (PCB) Statistical Program.

PCB Industry Growth Rates and Book-to-Bill Ratios Announced
Rigid PCB shipments declined 30.8 percent and bookings were down 16.6 percent in June 2009 from June 2008. Year to date, rigid PCB shipments are down 29.3 percent and bookings fell by 29.6 percent. Compared to the previous month, rigid PCB shipments grew 18.6 percent and rigid bookings increased 27.9 percent. The book-to-bill ratio for the North American rigid PCB industry in June 2009 continued climbing to 1.12.
Flexible circuit shipments in June 2009 went down 3.1 percent, but bookings are up 4.0 percent compared to June 2008. Year to date, flexible circuit shipments are up 1.5 percent and bookings are down 5.0 percent. Compared to the previous month, flexible circuit shipments went up 21.3 percent and flex bookings increased 28.7 percent. The North American flexible circuit book-to-bill ratio in June 2009 reached 1.02.
For rigid PCBs and flexible circuits combined, industry shipments in June 2009 decreased 29.0 percent from June 2008 and orders booked decreased 15.1 percent from June 2008. Year to date, combined industry shipments are down 27.3 percent and bookings are down 28.0 percent. Compared to the previous month, combined industry shipments for June 2009 increased 18.9 percent and bookings went up 28.0 percent. The combined (rigid and flex) industry book-to-bill ratio in June 2009 climbed to 1.11.
“Although PCB sales in June were still well below last year’s levels, the growth rates are improving,” said IPC President Denny McGuirk. “Bookings are recovering and that is reflected in the book-to-bill ratio, which is the highest we’ve seen in over three years,” he added. “That will help to drive stronger sales growth in the coming months.”
The book-to-bill ratios are calculated by dividing the value of orders booked over the past three months by the value of sales billed during the same period from companies in IPC’s survey sample. A ratio of more than 1.00 suggests that current demand is ahead of supply, which is a positive indicator for sales growth over the next two to six months.
Book-to-bill ratios and growth rates for rigid PCBs and flexible circuits combined are heavily affected by the rigid PCB segment. Rigid PCBs represent an estimated 91 percent of the current PCB industry in North America, according to IPC’s World PCB Production and Laminate Market Report.
The Role of Domestic Production
IPC’s monthly survey of the North American PCB industry tracks bookings and shipments from U.S. and Canadian facilities, which provide indicators of regional demand. These numbers do not measure U.S. and Canadian PCB production. To track regional production trends, however, IPC asks survey participants for the percent of their reported shipments that were produced domestically (i.e., in the USA or Canada). In June 2009, 88 percent of total PCB shipments reported were domestically produced. Domestic production accounted for 88 percent of rigid PCB and 83 percent of flexible circuit shipments in June by IPC survey participants. These numbers are significantly affected by the mix of companies in IPC’s survey sample, which may change slightly in January, but are kept constant through the calendar year.
Bare Circuits versus Assembly
Flexible circuit sales typically include value-added services such as assembly, in addition to the bare flex circuits. In June, the flexible circuit manufacturers in IPC’s survey sample indicated that bare circuits accounted for approximately 68 percent of their shipment value reported for the month. Assembly and other services make up a large and growing segment of flexible circuit producers’ businesses. This figure is also sensitive to changes in the survey sample, which may occur at the beginning of each calendar year.
Interpreting the Data
Year-on-year and year-to-date growth rates provide the most meaningful view of industry growth. Month-to-month comparisons should be made with caution as they may reflect cyclical effects. Because bookings tend to be more volatile than shipments, changes in the book-to-bill ratios from month to month may not be significant unless a trend of three consecutive months or more is apparent. It is also important to consider changes in bookings and shipments to understand what is driving changes in the book-to-bill ratio.
The information in IPC’s monthly PCB industry statistics is based on data provided by a representative sample of both rigid and flexible PCB manufacturers in the USA and Canada. IPC publishes the PCB Book-to-Bill Ratio and the PCB Statistical Program Report each month. Statistics for the previous month are not available until the last week of the following month.
