PCB design software is used by engineers to create and test circuit boards before permanently inserting them. It allows for easy component changes and can detect design flaws. Learning the software can take time, but it eliminates trial and error in the design process. The design is printed onto the circuit board and unnecessary conductor is removed through etching. High-end software can warn of design flaws before etching.
Printed circuit board (PCB) design software is used by electrical engineers and printed circuit board designers to map out and test a circuit board before inserting it permanently into a circuit board. A variant of computer-aided design (CAD) programs, this software offers a range of design capabilities. Using PCB design software, a designer can add and remove components in a circuit, change the voltages and resistance of various parts, or alter circuit paths with a simple mouse click or a few keystrokes, creating a working model of the circuit. long before the design is actually engraved on the circuit board.
The purpose of PCB design software is to create intelligently and efficiently designed circuits based on schematics. Using this software, electrical engineers or other properly trained individuals can replicate the function of a schematic design, print circuit boards, and produce a product that will perform all of the functions designed in the original schematic. Most PCB design software is also capable of pointing out minor design flaws, inconsistencies, and problem areas that can result in a poorly designed product. Depending on the individual software suite chosen for a project, it may have a pre-set arrangement of electrical and test components already configured to suit design projects.
The technique of using PCB design software is quite simple, but learning the individual software programs can be a significant investment of time. In most cases, the electrical engineer can insert the components and the software will automatically place them in the correct location and routing on the project. Sometimes minor changes need to be made to achieve a certain effect or in the case of experimental circuit designs.
Once PCB design software is used to design the circuit layout, the design is printed onto the copper-clad circuit board itself or a specially designed layout. The circuit board is then dipped into the etching solution to remove unnecessary conductor from the board, leaving only the PCB circuit design. By following this process, much of the trial and error process is eliminated from designing new and experimental circuits. Additionally, high-end PCB design software may be able to warn the user of design flaws or dangerous configurations before a design is actually etched onto expensive circuit boards.
