Hello, can you tell me the above a green machine has frame, why do you want to have a mechanical layer, what is the role here

CodePudding user response:

Mechanical layer is the actual dimension of components, draw the mechanical layer can avoid components overlap on the space,

CodePudding user response:

Machine frame is of little use, in general assembly components has certain offset, so generally larger components we leave back to 0.3 mm distance between small leave 0.1 mm as installing component redundancy, of course you also can regard him as a useful reference for other, such as the boundary of the BGA rework box, anyway this is a reference, not necessarily too many practical significance, because if your mind has a PCB with good pictures, you should know where is problem,

CodePudding user response:

This box assembly reference only
