AutoCAD Tutorial – The Explanation of Layers
This AutoCAD Tutorial can make a case for the way to created layers in AutoCAD for the electronic business.
While coming up with in AutoCAD, the drafting schematics, style PCB design, detailed fabrication list and assembly drawings are all drawn on completely different layers.
Here is a proof of layers that are usually created for an Electronic PCB design:
1. The silkscreen on the highest facet of the PCB
The silkscreen contains element outlines and legends etched with white ink on the highest facet of the PCB. The producing of PCBs desires a legend silkscreen containing the reference designators (components).
2. The circuit traces on the solder facet of the PCB
Electronic schematics consisting of symbols that represent the individual electronic elements that are required to make an AutoCAD drawing. These electronic symbols are interconnected with lines that represent the particular electrical connections and are annotated with text containing the specifications of the elements used. the fundamental schematic symbols are standardized and conjointly accessible as a library to be used in AutoCAD that simplifies the method of generating schematics.
3. The pads for through hole elements.
Libraries of endpoint symbols are accessible that, with varied hole sorts and sizes, ought to be incorporated into the drawing.
4. Any special solder mark patterns on the elements facet of the PCB.
The reference designators are used to see the situation of elements on the PCB, and used throughout producing, also as troubleshooting the PCB at a late time.
5. Drill symbols and attributes related to the pads of thro hole elements.
The drill attributes within the drawings offer the drilling details employed by automatic machines for drilling holes.
6. Drawing border, title & alternative details employed in documentation needed for producing.
A detailed list of elements needed for producing the PCBs may be extracted from the AutoCAD drawing. Once the layout is complete the AutoCAD drawing is converted to Gerber and Excellon file formats, that is business commonplace for photo plotting PCB design. These file formats are needed for producing PCB’s when using third party add-on software.
The following industries will like putting in place their layers the method it’s recommended during this AutoCAD Tutorial:
1. analysis and academic establishments for coming up with electronic systems.
2. Electronic equipment firms for style and producing of circuits, PCBs and prototypes.
3. Electronic engineers for coming up with and producing circuits, PCB’s and prototypes.
4. makers for extracting info out of the drawings and using it for production.
