Introduction to PCB Design and ORCAD
Printed Circuit Board (PCB) design is a crucial aspect of electronic product development. It involves the creation of a layout for the electronic components and the connections between them on a board. The design process requires specialized software tools to ensure accuracy, efficiency, and adherence to industry standards. One of the most widely used PCB design software is ORCAD, developed by Cadence Design Systems.
ORCAD is a comprehensive suite of tools for PCB design, including schematic capture, layout, and simulation. It offers a user-friendly interface, extensive libraries of components, and powerful automation features that streamline the design process. Many PCB design companies rely on ORCAD to deliver high-quality designs for their clients across various industries.
