TIP #074: You may not want to use a hierarchical design
Why? Hierarchical design may be hard to follow and read. It adds additional work and it can bring in unnecessary mistakes.
TIP #073: If you are not sure if a circuit is going to work ...
Why? This helps you to minimize number of revisions of your board.
TIP #072: Name schematic pages by short and clear names
Why? You will quickly find the page which you would like to open.
TIP #071: Consider not using autorouter
Why? People still do the best job.
TIP #070: You may want to use 1% resistors instead of 5%
Why? The price is almost the same and you do not need to stock both. Also, it may help with reliability and stability.
TIP #069: You can use an industrial hot air gun to replace
Why? Cheap, easy and works. You may need some practicing.
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.
