Yea, I work in the industry. There are players, but not exactly bountiful. Really the backbone of American electronics manufacturing is military spending. If the defense budget went away, there would be close to zero PCB manufacturers left. China makes higher quality boards, faster and for dramatically less money.

This applies for any manufacturing industry to be honest. US shipbuilding capability is so limited compared to China. It's only surviving because of military spending, but not in a healthy way. US made ships are of lower quality and cost much more, compared to European countries. It's the same for cars, busses, airplanes. Whole US policy is blocking the entry of busses manufactured outside NAFTA. US government is keeping Boeing alive by sending POTUS to marketing trips etc etc.
