Combined industry shipments of rigid PCBs and flexible circuits in November 2010 increased 11.8% from November 2009, with orders booked increased 5.0% from November 2009, according to IPC - Association Connecting Electronics Industries results from its North American Printed Circuit Board (PCB) Statistical Program. Year to date, combined industry shipments were up 18.1% and bookings were up 23.0%.
Compared to the previous month, combined industry shipments for November 2010 decreased 2.7% and bookings increased 1.7%. The combined (rigid and flex) industry book-to-bill ratio in November 2010 dipped to 0.96.
Rigid PCB shipments were up 9.7% and bookings increased 4.3% in November 2010 from November 2009. Year to date, rigid PCB shipments were up 18.6% and bookings have grown 23.4%. Compared to the previous month, rigid PCB shipments decreased 3.5% and rigid bookings increased 2.3%. The book-to-bill ratio for the North American rigid PCB industry in November 2010 fell to 0.96.
Flexible circuit shipments in November 2010 were up 38.8% and bookings grew 14.2% compared to November 2009. Year to date, flexible circuit shipments increased 13.2% and bookings were up 19.0%. Compared to the previous month, flexible circuit shipments increased 6.1% and flex bookings decreased 5.5%. The North American flexible circuit book-to-bill ratio in November 2010 dropped to 0.92.
“Year-on-year growth rates for rigid PCB and flexible circuit sales are still positive, but the rate of growth for rigid PCBs is slowing while the growth rate for flex is now increasing,” said IPC President and CEO Denny McGuirk. “Although sales are still strong, orders have slowed in both segments, due in part to seasonal effects this month. Slowing orders have driven the book-to-bill ratio downward over the past six 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 three months.
