The world’s largest tech companies are masters of their domains: Apple in phones; Google in search; Facebook in social media.

Why stop there? All three are going into financial services, and if past is prelude, they intend to dominate the space.

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.
