Learn to design your first printed circuit board (PCB) layout using KiCad 9.0 in this comprehensive 18-minute tutorial that transitions from schematic design to physical board creation. Open the PCB Editor and configure manufacturing constraints using real-world specifications from DigiKey's DKRed service, then master component placement by arranging footprints, utilizing ratnest toggles, cross-probing tools, and layer visibility controls. Resolve footprint mismatches such as extra pads on DC jacks, position components precisely using smart grid settings and keyboard shortcuts, and add mounting holes with reset local coordinates for accurate placement. Define board boundaries using Edge.Cuts layer with smooth corner fillets, then route electrical connections by dragging, grabbing, and flipping traces while learning to highlight nets and switch layers using vias. Optimize trace widths, edit multiple nets simultaneously, and create copper pour zones for ground and power distribution throughout your board. Inspect your design using the integrated 3D viewer, troubleshoot missing component models by switching from .WRL to .STEP files, and modify footprints for improved hand soldering such as TO-92 handsolder variants. Enhance your circuit by adding optional features like power-on LED indicators through proper schematic updates, validate your design using Design Rule Check (DRC) to eliminate errors, and preview the finished board with custom color schemes including the DKRed preset. Master essential shortcuts and professional techniques that accelerate layout workflow while improving design quality, understand thermal relief functionality for effective soldering, and prepare manufacturable PCB files ready for production ordering.
