PCB Design¶
Lession to learn for PCS Design
Plugin generates convenient BOM listing with ability to visually correlate and easily search for components and their placements on the pcb.
- Cut some holes in your boards to make it easier to align.
- Add proper programming and debugging interfaces to make it easier to reprogram the chips.
- Align all of your pin headers to be on the same 0.1″ grid

Dealing with Radiation¶
With exposure to radiation the circuit takes more time to change states. This lowers the frequency that the chip can be used at.
Ways to Mitigate Radiation effect:
1. To counter act this effect you can shield you electronics.
2. Change Transistor layout design
- Use more voltage so it takes more errors to flip bits
- Store information in multiple nodes to add repetition
- So everything 3 times and take which has majority
3. Over design the circuit that has a longer lifetime
Tips¶
- Route both the Ground and Voltage side by side to minimize EM interference on the board
- Buffer analog ground from digital ground
- Do not use auto-router for Analog signals
- High speed devices closest routing
- Have atleast 1 ground plane
- Power traces wider than other traces
