BANNOCKBURN, Ill., USA, January 31, 2013 — IPC — Association Connecting Electronics Industries® announced today the December 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 were down 16.1 percent in December 2012 from December 2011, and bookings decreased 8.8 percent year over year. Year to date, rigid PCB shipments declined 5.5 percent and bookings decreased 1.7 percent. Compared to the previous month, rigid PCB shipments were up 7.1 percent and rigid bookings increased 19.0 percent. The book-to-bill ratio for the North American rigid PCB industry in December 2012 recovered to 0.99.
Flexible circuit shipments in December 2012 were up 6.7 percent, and bookings were up 9.4 percent compared to December 2011. Year to date, flexible circuit shipments decreased 1.5 percent and bookings decreased 10.0 percent. Compared to the previous month, flexible circuit shipments decreased 7.4 percent but flex bookings were up 20.2 percent. The North American flexible circuit book-to-bill ratio improved to 0.84.
For rigid PCBs and flexible circuits combined, industry shipments in December 2012 were down 14.5 percent and bookings decreased 7.5 percent, compared to December 2011. Year to date, combined industry shipments were down 5.2 percent and bookings were down 2.4 percent. Compared to the previous month, combined industry shipments for December 2012 increased 5.7 percent and bookings increased 19.1 percent. The combined (rigid and flex) industry book-to-bill ratio in December 2012 rose to 0.98.
“North American PCB book-to-bill ratios appear to have begun recovering after a downward trend that began in the second quarter of 2012,” according to Sharon Starr, IPC director of market research. “The industry’s sales ended 2012 at 5.2 percent below 2011.”
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 three 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 90 percent of the current PCB industry in North America, according to IPC’s World PCB Production 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, IPC asks survey participants for the percent of their reported shipments that were produced domestically (i.e., in the USA or Canada). In December 2012, 82 percent of total PCB shipments reported by survey participants were domestically produced. Domestic production accounted for 82 percent of rigid PCB and 80 percent of flexible circuit shipments in December by IPC’s survey participants. These numbers are significantly affected by the mix of companies in IPC’s survey sample, which change slightly in January, but are kept constant through the remainder of the year.
Bare Circuits versus Assembly
Flexible circuit sales typically include value-added services such as assembly, in addition to the bare flexible circuits. In December, the flexible circuit manufacturers in IPC’s survey sample indicated that bare circuits accounted for about 42 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.
