Just to manufacture these you have to get the certain raw materials. The manufacturing process has many aspects and tiny details. One mess up on the manufacturing part and the rest of the board could be ruined. This is why a lot of manufacturing buildings have automated machines. These help them mass produce, but there are still smaller sites that are only made by specialists. These are usually the boards that go past $500.
Workers
