PCB Manufacturing drawing and PCB assembly drawing

PCB Manufacturing drawing and PCB assembly drawing

Design drawings are not strictly required for all PCB fabrication and assembly projects, but they can help to make your intentions clearer to our production team, particularly regarding special requirements. We recommend you include design drawings for projects with a high number of layers or components.

1.PCB Manufacturing Drawing
PCB manufacturing drawings only contain that information which is needed for the fabrication of the PCB. This could be information such as the project name, board dimensions, board thickness, tolerances, material, copper weight, number of copper layers, or surface finish. These may be a list of notes beside the board’s artwork or listed in a separate file. Other special information may also be included in the manufacturing drawing, such as controlled impedance requirements, via-in-pad tenting, gold-plated edge connectors, and so on.

2.PCB Assembly Drawing
PCB assembly drawings contain that information that is needed for assembly of the various components onto a PCB. Basic component information, such as position and orientation, are provided on this drawing, along with special requirements, such as height limit. Three-dimensional renderings could also be included to clarify special requirement areas but are not necessary for typical boards.
