The bare circuit board may be assembled on different levels. A cheaper level of the board may have some missing parts that go into a final product at a cheap level. Some boards with special features tend to face the same problems, あまりにも. Label part numbers to help identify this problem.
By the way, the assembled board might have a stick-on label with the final assembly number.

My project have gone through from design, prototype to mass production after lots of discussion and adjustment. Now the manufacturer are making our products in their product lines. And I would like to know is there any differences between the prototypes in my hand now and the final products output by the manufacturer?
I know the paste mask layer is also called the stencil layer. It’s only used for assembly. I want to know if the paste mask layer (上層と下層の両方) is necessary for through hole components. For SMD components I know the paste mask layer is required to solder the components. Is it necessary for through hole components?
製造中のビアインパッドを映したビデオをオンラインでいくつか見ます. でもそれは良い方法とは思えない, それは...ですか?
