North American PCB Industry Sales Up 6.7% in May
June 23, 2023 | IPCEstimated reading time: 1 minute
IPC announced the May 2023 findings from its North American Printed Circuit Board (PCB) Statistical Program. The book-to-bill ratio stands at 0.89.
Total North American PCB shipments in May 2023 were up 6.7 percent compared to the same month last year. Compared to the preceding month, May shipments were down 1.9 percent.
PCB bookings in May were up 4.1 percent compared to the same month last year. May bookings were up 6.7 percent compared to the preceding month.
“The North American PCB market looks pretty balanced this month. Shipments remain strong and we saw the first year-over-year rise in bookings we've seen since November 2022,” said Shawn DuBravac, IPC’s chief economist.
Detailed Data Available
Companies that participate in IPC’s North American PCB Statistical Program have access to detailed findings on rigid PCB and flexible circuit sales and orders, including separate rigid and flex book-to-bill ratios, growth trends by product types and company size tiers, demand for prototypes, sales growth to military and medical markets, and other timely data.
Interpreting the Data
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 three to twelve months. A ratio of less than 1.00 indicates the reverse.
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 reflect seasonal effects and short-term volatility. Because bookings tend to be more volatile than shipments, changes in the book-to-bill ratios from month to month might not be significant unless a trend of more than three consecutive months is apparent. It is also important to consider changes in both bookings and shipments to understand what is driving changes in the book-to-bill ratio.
IPC’s monthly PCB industry statistics are based on data provided by a representative sample of both rigid PCB and flexible circuit manufacturers selling in the USA and Canada. IPC publishes the PCB book-to-bill ratio by the end of each month.

Fresh PCB Concepts: Designing PCBs for Harsh Environments—Reliability Is Engineered Upstream
04/23/2026 | Team NCAB -- Column: Fresh PCB ConceptsWhen engineers hear the phrase “harsh environment,” they usually think of the extreme temperature swings, vibration and shock, pressure changes, or radiation in aerospace. However, aerospace is not the only harsh environment where electronic assemblies must survive. Automotive power electronics, downhole oil and gas tools, marine controls, rail systems, defense platforms, and industrial automation equipment all expose PCBs to environments that are equally unforgiving. The stress mechanisms may differ, but the physics does not.
The Right Approach: The End of an Era—DoD Proposes MIL-PRF-31032 Cancellation
04/21/2026 | Steve Williams -- Column: The Right ApproachThe Defense Logistics Agency has initiated formal proceedings to cancel the military's primary performance specification for printed circuit boards, a move that could reshape how the U.S. defense industrial base qualifies and sources one of its most critical electronic components. On March 4, 2026, DLA Weapons Support issued a memorandum to military and industry coordination activities announcing that MIL-PRF-31032, along with its six associated specification sheets, has been proposed for cancellation. A 30-day comment period was allotted, with concurrence or comments due by April 3, 2026.
