IPC announced today the January 2022 findings from its North American Printed Circuit Board (PCB) Statistical Program. The book-to-bill ratio stands at 1.18.

Total North American PCB shipments in January 2022 were up 7.7 percent compared to the same month last year. Compared to the preceding month, January shipments fell 22.1 percent.

PCB year-to-date bookings in January were up 6.3 percent compared to last year. Bookings in January fell 28.1 percent from the previous month.

“Supply chains are showing some early signs of improvement, which is helping fuel shipment growth at the start of the year. But backlogs remain higher as manufacturers work through strong orders,” said Shawn DuBravac, IPC chief economist. “We believe supply chain constraints will continue to slowly ease through the remainder of the year which should help companies improve shipment schedules.”

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.

IPC announced today the January 2022 findings from its North American Electronics Manufacturing Services (EMS) Statistical Program. The book-to-bill ratio stands at 1.58.

Total North American EMS shipments in January 2022 were down 6.0 percent compared to the same month last year. Compared to the preceding month, January shipments fell 14.9 percent.

EMS bookings in January rose 28.7 percent year-over-year but fell 17.9 percent from the previous month.

“While shipments slipped in January, orders were extremely strong, pushing the book-to-bill ratio to the second highest level on record,” said Shawn DuBravac, IPC chief economist. “Parts availability is likely continuing to hinder production despite some early signs that supply chains are improving. Geopolitical risk is casting a cloud of uncertainty that will likely produce a shift in downstream market demand over the coming months,” DuBravac added.

Companies that participate in IPC’s North American EMS Statistical Program have access to detailed findings on EMS sales growth by type of production and company size tier, order growth and backlogs by company size tier, vertical market growth, the EMS book-to-bill ratio, 3-month and 12-month sales outlooks, and other timely data.
