PCB Design with KiCad and Soldering Surface-Mount Parts

10 Lektionen in dieser Stufe

1. From Breadboard to Board: Planning a PCB Project
   Define board size, connectors, mounting and component choices before drawing. · Lab: Write a one-page board specification for your sensor node.
2. Schematic Capture in KiCad
   Place symbols, wire nets and use labels and power symbols for a readable schematic. · Lab: Draw the schematic of a microcontroller sensor node with regulator and programming header.
3. Symbols, Footprints and Reading Package Drawings
   Match each symbol to the right footprint and create a custom one from a drawing. · Lab: Create a footprint for a connector from its mechanical drawing and verify it on a 1:1 print.
4. Electrical Rules Check and Designing for Debugging
   Clear rule violations and add test points, indicator LEDs and jumpers. · Lab: Run the check, fix all issues and add five test points.
5. Component Placement and Board Outline
   Arrange parts by signal flow, keep decoupling close and define outline and mounting holes. · Lab: Place all components of your board and review it in the 3D viewer.
6. Routing Traces, Widths, Vias and Ground Pours
   Route power and signals with suitable widths and a solid ground reference. · Lab: Route the board completely with a ground pour on both layers.
7. Design Rules Check, Gerber Files and Ordering Boards
   Verify against manufacturer capabilities and export a correct fabrication package. · Lab: Run the check, export Gerber and drill files and inspect them in a viewer.
8. Through-Hole Assembly and Inspecting Joints
   Assemble in a sensible order and judge joint quality under magnification. · Lab: Complete a through-hole kit and rework any doubtful joints.
9. SMD Soldering with Iron, Paste and Hot Air
   Solder chip components, small-outline ICs and fine-pitch parts and remove bridges. · Lab: Complete an SMD practice kit using both iron and hot air.
10. Board Bring-Up: Power First, Then One Block at a Time
    Test a new board safely with current limiting and staged checks. · Lab: Bring up your assembled board following a written checklist and record all measurements.
