TIP #044: When doing placement under BGA, ...
Why? When placing the components - second time, you will know which direction you have some free space.
TIP #043: List all pin alternate functions in SCH symbol
Why? You see directly and clearly from your schematic how the pins can be used.
TIP #042: Create Assembly Drawings
Why? Very often this is used during board assembly and it is very useful during debugging.
TIP #041: Add more information on silkscreen
Why? Helps during assembly. Can prevent placement issues during PCB design (e.g. too close, wrong rotation,…)
TIP #040: Use the chip support as little as possible
Why? In most cases, they will not help you.
TIP #039: Be careful how you order pins on your connectors
Why? For example, you may want GND/PWR separate CLK signal from the others, it helps minimize crosstalk between signals on a cable.
TIP #038: Place fiducials in the PCB corners
Why? Assembly house uses them.
TIP #037: Use “.Checked PCB” ".Checked SCH" parameters
Why? Helps you to identify symbols and footprints which you need to check, helps to speed up schematic drawing process
TIP #036: Buy a good mouse
Why? When doing schematic and layout for weeks / months / years and moving your hand all the time, you really need a good mouse.
TIP #035: Use ferrite beads or 0R resistors on powers
Why? It helps with power noise filtering, easy to measure currents, circuit can be disconnected, …
TIP #034: Have a look at what your competition is using
Why? In some cases you may want to use exactly the same components because of software / hardware compatibility.
TIP #033: If you can, try using leaded tin when repairing
Why? It melts at lower temperature and behaves better than un-leaded tin
TIP #032: Always do testing in environmental chamber
Why? It helps you to find possible problems before mass production
TIP #031: Include page number in Schematic page name
Why? It helps you quickly jump to the right page
TIP #030: Do Paper model of your board
Why? It’s a simple way to check if everything fits correctly and if everything is in the right place.
