What is PCB Design Software?
Before diving into the top 9 free PCB design software, let’s first define what PCB design software is and why it’s essential for creating printed circuit boards (PCBs).
PCB design software is a specialized tool used to create the layout and design of PCBs. It allows users to place components, route traces, and generate manufacturing files for PCB fabrication. PCB design software streamlines the design process, reduces errors, and ensures that the final product meets the required specifications.
Why Use Free PCB Design Software?
