Precision PCB Fabrication, High-Frequency PCB, High-Speed PCB, Standard PCB, Multilayer PCB and PCB Assembly.
The most reliable PCB & PCBA custom service factory.
The layers that need to be output are:
(1). Wiring layers include top/bottom/middle wiring layers;
(2). The power layer includes the VCC layer and the GND layer;
(3). The solder mask includes the top solder mask and the bottom solder mask;
(4). The silk screen layer includes the top silk screen/bottom silk screen;
(5). In addition, the drilling file NCDrill must be generated.
2. Select the Board Outline when setting the Layer of each layer.
3. If the power layer is set to Split/Mixed, then select Routing in the Document item of the AddDocument window and use PourManager's Plane Connect for copper pour on the PCB diagram before outputting the gerber file; if it is set to CAMPlane, select Plane in When setting the Layer item, add Layer25 and select Pads and Vias in the Layer25 layer.
4. Press Device Setup in the device setting window to change the value of Aperture to 199.
5. Do not select Part Type when setting the Layer of the silk screen layer. Select the Outline Text Line of the top and bottom layers and the silk screen layer.
6. When setting the layer of the solder mask layer, selecting a via hole means that no solder mask is added to the via hole, and not selecting a via hole means that the solder mask is determined according to the specific situation.
7. Do not make any changes to the default settings of PowerPCB when generating drilling files.
8. After outputting all gerbera files, open them with CAM350 and print them. The designer and reviewer will check according to the "PCB checklist".
The above is the introduction to the Gerber level settings of PCB design. Ipcb is also provided to PCB manufacturers and PCB manufacturing technology
