Common Mistakes in PCB Layout Design

This video tutorial challenges a software engineer to design their first PCB, revealing common mistakes beginners make in PCB layout. Learn about Arduino compatibility, proper component placement, track routing techniques, and design best practices. Discover the importance of text placement, LED positioning, board naming conventions, and connector labeling. Master essential PCB design concepts including horizontal/vertical routing, net color usage, appropriate track widths, and the differences between 2-layer and 4-layer PCBs. Explore critical aspects like via placement, power regulation, stitching capacitors, thermal relief for through-hole pins, USB design considerations, proper clearances, and signal routing. The hour-long tutorial concludes with tips on aesthetic design, reference designator placement, and performing DRC checks to ensure functionality.
