Advantages of Using Draftsman to Create a PCB Assembly Drawing
Standard assembly drawing applications are not designed for creating drawings specifically for electronics assemblies. Printed circuit boards have complex features and placements that are not easy to render in most drafting applications, so significant time may be required to create these drawings. Something faster is needed to quickly create a production-grade drawing your assembly house can use to build your PCB.
The Draftsman feature in Altium Designer offers an elegant, yet powerful solution to make these tasks easier. You can quickly create an assembly drawing with specific views of the PCB, including selected component information, dimensions, title blocks, and much more. Your assembler will have a clear understanding of where components must be mounted, and it's easy for inspection service to verify this.
What Goes Into a PCB Assembly Drawing?
Every assembly drawing needs to have some basic information that shows the location and orientation of major components on the PCB. Some of the primary information required to produce an assembly drawing includes:
- An assembly drawing with placement of major components
- Top, front, and side view of the PCBA
- Fiducials and/or mounting holes clearly visible
- A set of PCB assembly notes
- Callouts with any important assembly information
- Portions of the BOM that require any special assembly instructions
- Title block with company and artist information
The goal of an assembly drawing is to help the assembler define the orientation of the bare board for assembly equipment, which will then be used to program automated assembly equipment. With an assembly drawing that shows the locations of the major components, there is much less room for error
To show some of the important information found in an assembly drawing, we created an example Draftsman document that highlights the available features and functionality. In the drawing below, we've included all the information an assembler might need to see to ensure the board is assembled and inspected correctly.
