When you generate a schematic, you are connecting a collection of symbols (components) together in a unique way, creating your unique electronic product.īelow are the steps involved in PCB schematic creation using Altium Designer: Schematic generation is the process of creating a logical representation of the electronic circuit. An example of the schematic diagram is shown below. If the design uses a hierarchical schematic, where numerous functional schematics are interrelated with each other, the schematic defines the relationships between groups of components in different schematics. A schematic shows the components that are used in the design and how they are connected together. In this phase, the design is entered into the schematic tool (Altium, Allegro, etc). Step 1: PCB schematic creationĪ schematic diagram is a representation of the elements of a system using abstract and graphic symbols. In this section, we will go through the different steps that are involved in designing a PCB using Altium Designer. To design a successful PCB, it is essential to follow the processes and check through the checklist at every milestone. Each stage has its own defined processes and checklists. The design process comprises various different stages. In this stage, the board parameter settings, board outline, component placement, routing, and production document generation are completed. During this stage, the stack-up design is also completed. During the validation process, the manufacturing part numbers (MPN) and vendor part numbers are verified. The next stage of design is the pre-layout stage, in this stage, the BOM from the schematic is validated for long lead time components and obsolete components. These nets will become traces on the circuit board. A schematic consists of component symbols and net connections between the symbols. This block diagram is then developed into schematic designs using CAD software. The first step involved in PCB design is to draw your concept block diagram on a paper. 3 Popular PCB design software Overview of PCB design
