North American Electronics Business Indicators Still Going Strong

North American printed circuit board (PCB) sales growth continued to climb in March 2018 and electronics manufacturing services (EMS) sales rebounded after three months of positive but slowing growth. Semiconductor sales growth remains strong but has started to come down from its fourth-quarter 2017 peak. Growth in all three industries remained in positive territory. These growth rates are based on three-month rolling averages.

The U.S. Purchasing Managers’ Index (PMI), which tends to lead industry sales by two to six months, remained strong in March 2018. It has been trending upward over the past year and a half and has been in positive territory (above 50) for more than two years. The 3/12 rate of change for U.S. New orders for electronic products, which leads industry sales by one to three months, increased and remains strong.

Another leading indicator, IPC’s PCB book-to-bill ratio, is based on three-month rolling averages of orders and sales, and normally leads industry sales by three to nine months. The ratio has been in positive territory for the past 14 consecutive months, driven mainly by growth in orders. The book-to-bill ratio came down to 1.13 in March from a 12-year high earlier in 2018, but remains very strong. Ratios above parity (1.00) indicate greater demand than supply, which may be a precursor of sales growth for electronics manufacturers, especially when a run of positive ratios over several months is seen. These indicators suggest the likelihood of continued sales growth in the industry in 2018.
