Some electrical engineers find the process of designing PCBs a simple routine. However, for other stakeholders it is a nightmare. This contribution takes a closer look at the basic principles of designing PCBs via Computer Aided Design (CAD) software applications.
Target group Workers in SME, trainers from various area of industry, high school teachers
When designing a PCB one must start with the electrical connection scheme. Most of recently used CAD applications have two separate editors for designing both schemes and power circuit boards. Transfer between them is carried out through the “exchange” file referred to as “Netlist”.
Outwardly, the use of schematic capture is similar to the traditional drafting process, where graphical symbols for circuit elements (parts, wires, etc) are rendered in drawings, which become a record of the design. Using computer-aided design provides many benefits, by automating the drafting process and allowing easy editing of the design layout. For example, each schematic sheet is an independent design document. An automated system links these sheets when they are used together in a hierarchical project. By recognizing these links, it is possible for the designer to globally edit and perform design verification across project sheets, or generate a bill of materials for an entire project in a single operation.
The PCB Editor is a „layered“environment. You create your board design by placing objects on these layers. These layers are either „physical“ layers, form which the fabrication information is created, or system layers, such as the Connect layer which displays the enrooted connections. Physical layers include the signal layers, internal plane layers, and silkscreen, solder mask and paste mask layers.
