Allegro Gerber Operation Process#
- Add OUTLINE to the BOTTOM and TOP layers.
- Add a Silkscreen folder.
You can copy the first two layers and rename them.
Add Silkscreen.
Add Package Silkscreen.
Add Reference Designator Silkscreen.
The top layer silkscreen is the same.
- Add a Solder Mask folder.
The solder mask layer is used for creating PCB windows. Areas with solder mask do not have solder mask.
Add Solder Mask under the Board.
Add Solder Mask for Packages.
Add Solder Mask for Pin Pads.
The top layer is the same.
- Add a Stencil folder.
The stencil layer is mainly used for applying solder paste. Send this file to the assembly factory.
Add Stencil for Pin Pads.
Add Stencil for Package Geometry.
The top layer is the same.
- Add a Drill folder.
The Drill folder is mainly used to place reference information, such as the final drilling table or dimension annotations, or other text instructions, such as the designer, design time, for reference by the manufacturer.
Add SubClass for Dimension Annotations.
Add SubClass for Drill Symbols.
Finally, we can also create two films for displaying pin pads and silkscreen during layout.
This way, when we use these two layers during layout, we can clearly see the pin pads and silkscreen of the components.
However, it is important to note that when generating Gerber files, these two films are not required and should not be provided to the PCB manufacturer.
