What specialized technicians are needed to manufacture a medical instrument?

I think the personnel to is not important, there is a full understanding of the instrument can be, the key is that this person needs to be proactive to realize their own ideas. Even if the idea is perfect, from drawing to actual samples need more than one production department to support, can go to the relevant factory to make.

For example, if there are mechanical parts, you can go to a machining company to make them; if there are circuit boards, you can look for PCB printing companies to order them; and finally, there are housings, which you need to find a way to make out of materials like plastic or metal. You can't have a small company that encompasses all of the above production lines. As long as you have the technology and money, most of the work can be let other companies to do for you.
