TIP #014: If you have an exposed pad, consider ...

Why? It helps during soldering.

TIP #013: Be aware, connectors may need to be on the edge

Why? You may want the connectors to be touching the enclosure. Some connectors have springs, others have panel around them.

TIP #012: Put useful notes into schematic

Why? So you do not forget about important stuff, so you do not have to look for the information again and again

TIP #011: Don’t forget to place mounting holes on your board

Why? If there are no mounting holes, how you are going to fit it into enclosure or a system?

TIP #010: Once you name a net, always copy and paste its name

Why? Because if you write it manually you can make a mistake.

TIP #009: Choose two or three biggest component suppliers ...

Why? It makes manufacturing easier.

TIP #008: You may want to use multiple VIAs in high current

Why? One VIA only can carry limited current (e.g. 1 - 1.5A).

TIP #007: Set the right height of your table

Why? Just moving your table up may stop your back pain.

TIP #006: Always create specific component type

Why? If you use a generic resistor schematic symbol, then always when you generate a BOM (Bill of Material), you will have to manually edit it.

TIP #005: Make small test circuit boards

Why? You may be surprised how the first revision of a simple circuit may not work the way as you are expecting.

TIP #004: Add a page reference next to the ports

Why? You can very simply see on what page(s) the signal continues.

TIP #003: Use “+” sign for your power net names

Why? It’s a very simple way to identify power nets (especially in layout), makes it simple to filter or order power nets , it’s very simple to use them in rules

TIP #002: Always spread signals if you have space

Why? It improves your design and layout.

TIP #001: You can have crosstalk on a low frequency

Why? Crosstalk depends on speed of rising / falling signal edge (how fast signal changes from low to high or high to low).
