TIP #068: Place tall components on one side of PCB
Why? One wrongly placed tall component can increase the total height of the board.
TIP #067: Be sure you fanout all the BGA pins before you ...
Why? It is very hard to add something later.
TIP #066: Include voltage value in power net name
Why? You need to be sure, that you are connecting signals with the same voltage levels. It also helps during debugging and schematic checking.
TIP #065: If you are not sure, add it there
Why? It will speed up development process. You can always remove it later.
TIP #064: Backup and possibly do versioning of your project
Why? Anyone can lose the data on hard drive. And it can happen anytime …
TIP #063: Consider to place analogue circuits in corners
Why? You may not want to place it in the middle of the board where all the currents and signals are running.
TIP #062: On the cover page, include status of the schematic
Why? Everyone reading your schematic will know how accurate it is and if they should report you any possible mistakes.
TIP #061: Do not forget about VIA aspect ratio
Why? If you do not follow VIA ratio recommendations, it may not be possible to manufacture your PCB.
TIP #060: Use the same number of Pins and Pads between ...
Why? You want to clearly see from schematic where each pin is connected. It's very important when checking schematic and connections.
TIP #059: Use optional resistors to re-route
Why? You will have one PCB with more options to meet different customers needs.
TIP #058: Create board variants
Why? It’s going to save you a lot of time and minimise mistakes in BOMs
TIP #057: If you are testing your prototype ...
Why? This way, you may quickly damage all your prototypes. First, figure out what’s wrong.
