Well, you must have heard of PCBs, haven't you? PCBs or Printed Circuit Boards are used to offer mechanical support to various physical components. They are also used to connect the components to electricity so that they can perform a particular function. The printed circuit boards consist of a flat sheet made of insulating material and a layer of copper foil. The entire object is laminated on a conductive substrate. The substrate mostly used is fiberglass and the conductive material used is copper. The protective coating is made out of solder. So, let us have a look at how the PCB components are designed.
Creating the schematic design: The first step to designing a PCB is creating the schematic design. This is the blueprint of the original PCB and it will provide you with the logical representation of the various components of the circuit. Each component is going to be identified by a symbol on the schematic design. The designing phase is the most important phase and it is going to determine how exactly the product is going to be made. So, you need to have a very clear idea about your requirements so that you are able to design the schema accordingly.
PCB layout planning: Next, you will have to plan the layout of the entire project. This is done after you have placed all the symbols at their desired location and have connected them. During the layout planning phase, you will be creating models of the physical components by using the required tools. You will also have to make sure that the nets do not come in contact with each other. Otherwise, there will be a short circuit. You are also going to determine the shape and structure of the original PCB circuit in this stage itself.
Component placement planning: Once you have planned out the layout, you are going to plan out where exactly you are going to place the different components. This is going to help you in deciding how many PCB layers you are going to need. You will also have to consider various other technical specifications. Here, the fixed PCB components are mostly placed in the first layer while the critical components are placed in the next layer. The supporting components are always placed close to the critical layer while the terminating components are present in the top layer.
Connection routing: Now you will have to create the connections between the various components. There are different methods of connection routing including manual routing, semi-automated routing, auto interactive routing, etc. You need to have a very clear idea of the connection routing procedure and get your PCB built accordingly.
Designing your circuit board: This is the final stage of the designing process. Here the designer will lay out all the components in their places. He will also connect the components by means of wires. The design will also be exported in CAD format as per the industrial standards. The product will then can be tested and it will then reach the manufacturing phase.
