The solder masks the lower layer- pcbname.GBS.The solder mask upper layer- pcbname.GTS.The essential layers you need for a 2-layer circuit board are: Likewise, press the Plot tab to produce the corresponding layers. On your File menu, proceed to the Plot function and select the appropriate layers, as illustrated in the diagram below. Alternatively, you can press the "PCBNew" tab to open the circuit board editor. Without further ado, let us dive into the process of generating Gebers in Kicad!įirst, open your Kicad project. What you need to do is to choose the appropriate layers and make the DRILL file. Generally, it is much easier to create Gerber files via Kicad than other circuit board design tools. We will discuss how to generate Gerber files using Kicad, Altium Designer, and Eagle software. It is essential to realize that various PCB design tools have distinct operations steps of Gerber file creation. Additionally, regarding the two layers containing similar design information, you should still generate your Gerber files one by one to avoid any mix-up. Generally, Gerber files come with design information of conductor, solder mask, and silkscreen layers. Hence, to ensure the production process proceeds as planned and your end products are reliable, you should learn to make Gerber files independently. Still, even if both of you use the same design software, generating Gerber files by yourself is crucial in preventing possible errors resulting from different terms. Further negotiations and requests will consume your time and affect the manufacturing process significantly. In case your manufacturer specifies that they are using different software, you should make Gerber files by yourself. A comprehensive PCB information outlines multiple procedures, such as machining processes that you should carry out and others.įirst, you can barely ensure that your manufacturer uses the same software you used in the design process. Mostly, surface riding and overlaid holes come in various templates. Besides, there will be templates containing different drill holes, their position, and use. There would be two templates for the solder mask and silkscreen pictures for your manufacturer to include on the circuit board's lower and upper parts. A picture of the copper layer to be placed on the upper part of the board.A picture of the copper layer to be placed on the lower part of the board.Sometimes, you can send over eight documents for a two-layered board to your PCB manufacturer. Remember, you can use these files for circuit board fabrication and assembly.Ī Gerber file adheres to the basic ASCII vector setup, and it contains the following features:Īgain, there is a Gerber file for every drill span and image layer of the PCB found in a single template. Gerber files define the requirements in every product development step. However, that is not true as you have to refer to Gerber file guidelines while keying in the information. Does this sound simple? I know you may think it is a system that automatically makes designs upon entering the data. Likewise, you need to enter data into these systems to create the designs. Typically, you will design your PCB in CAD systems that use manufacturing information to produce two or three-dimensional circuit board designs. It refers to the PCB features, like solder mask layers, legend, drill template, etc. The name originates from Gerber Systems Corp- the first company to develop Gerber files. The Importance of Gerber Files in PCB ManufacturingĪs mentioned earlier, a Gerber file is one of the essential elements of PCB design.
