BANNOCKBURN, Ill., USA, October 25, 2011 a IPC a Association Connecting Electronics Industries announced today the September 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 13.1 percent and bookings were down 19.9 percent in September 2011 from September 2010. Year to date, rigid PCB shipments decreased 0.4 percent and bookings declined 10.8 percent. Compared to the previous month, rigid PCB shipments increased 3.5 percent and rigid bookings decreased 8.9 percent.
The book-to-bill ratio for the North American rigid PCB industry in September 2011 dipped just below parity at 0.99. Flexible circuit shipments in September 2011 were down 0.7 percent and bookings declined 1.8 percent compared to September 2010. Year to date, flexible circuit shipments increased 1.6 percent and bookings increased 3.0 percent. Compared to the previous month, flexible circuit shipments increased 20.1 percent and flex bookings were up 9.9 percent. The North American flexible circuit book-to-bill ratio in September 2011 fell to 0.97. For rigid PCBs and flexible circuits combined, industry shipments in September 2011 decreased 12.0 percent from September 2010, as orders booked decreased 18.4 percent from September 2010. Year to date, combined industry shipments were down 0.2 percent and bookings were down 9.6 percent. Compared to the previous month, combined industry shipments for September 2011 increased 4.9 percent and bookings decreased 7.3 percent.
The combined (rigid and flex) industry book-to-bill ratio in September 2011 declined to 0.99. Sales and orders were both under last years levels in September, said IPC President CEO Denny McGuirk. Bookings have been especially sluggish and that has caused a drop in the book-to-bill ratio although it is still very near parity, which suggests that flat sales is the likely near-term scenario. 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 IPCˉs 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 89 percent of the current PCB industry in North America, according to IPCˉs World PCB Production Report.
