2.1 KiB
One Sided Two Layer Board
- Remove all components and measure them
- Sand away the solder mask from PCB, both sides
- Add all components, values, designators and packages to KiCad schema editor
- Import all components to layout editor; hit F8 to keep syncing with the schema editor
- Take photo of front/back of PCB
- Flip back image to align with front when imported
- Add images of front PCB in KiCad on user layer
- Double click image and set scale factor to actual PCB height divided by original height of imported photo
- Double click to lock image
- Select the back layer of PCB
- Import back photo an scale also
- Align front and back images by hiding/showing front layer
- Place all components using the front image as a guide
- Switch to showing components in outline mode to help see traces
- Hold Control key to select pads, switch to schematic editor and the connections will be highlighted; join them.
- Keep traces same width; use Q key while routing a trace to change width, V to add a via
- Mark and join all ground traces using a Ground symbol; add VCC markers as needed
- Right click unused pads and select footprint editor; select unused pads and remove them
- In schematic editor, select any unused pins and delete them
- Continue adding all components until done
- Use image outline to set a cut line for the board
- Add a thermal zone assigned to ground and set thermal relief gap to match image; hit B to fill in zone
- Add thermal via's underneath chips as needed
- Trace connectors on underside of PCB
- Note you can change trace thickness as you draw
- Switch to other side/trace when routing using V in layout editor
Notes
- Diodes have A for anode (positive side) and K for cathode (negative/ground side).
