- PCBExpress/Sunstone: Web site where to order PCB from.
Process
- First create schematics with TinyCAD
- Then route the lines on a 4-layer board with FreePCB
- Check the CAM files generated by FreePCB with ViewMate
- Once the output files are ready, upload them to PCBExpress (accept 4-layers+mask option).
An Example
- We'll create a PCB for the following simple circuit taken from seekic.com:
TinyCAD
- Open TinyCAD
- Open the 74TTL library in the left pane
- Pick the Hex Inverters
- Drop two inverters on the blank schematics pane
- Update the reference for each gate (U1A and U1B) in the Tool Options window.
