I was all set this month to write about plating using additive manufacturing, but when someone pointed out just how subtractive the industry really is, it compelled a change in plans.

It came in the way of an email from Dr. Hayao Nakahara, the preeminent market researcher in the printed circuit industry. Naka, as he is known to friends, shared results of a months-long study of the North American PCB supply base.

This was no easy task. Naka started with the Fabfile database, long the favorite child of Harvey Miller. Harvey, who is about to hit 100 years old (!), gave Naka the keys to the car. In turn, Naka reached out to every company on that list, diligently revising and updating. The effort took more than three months.

For more than 20 years, PCD&F/CIRCUITS ASSEMBLY has been proud to be the exclusive publisher of the annual NTI - 100 list of the world’s largest board fabricators.

One of the striking changes over the years has been the reshaping of the industry geographical landscape.

In this year’s rankings, which begin on page 32 of the August 2022 issue, see how many Europe- and US-based companies are in the top 25. I'll save you the suspense. One each: AT&S and TTM Technologies, respectively. Long gone are the days when Photocircuits, Sanmina, Hadco, Viasystems and the like dominated the top of the chart.
