The company I work at outsources tons of work. I guess it is for the best. We work with electronics. This is a tough area to work in. To produce a single chip you will need to invest millions in machinery. Of course, even after the investment, you can’t be sure that you will produce something that will actually work. Surviving the competition calls for finesse. I was the one responsible for finding the right dielectric isolation for our new amplifier. Actually, I found the company that did the isolation for us. This was the best solution. The company we did business with, is in this line of business for more than thirty years. You can’t go wrong with such companies.
