...

For IPC compliant packages where the manufacturer recommended footprint differs from the IPC standard, follow the IPC standard unless specific conditions exist where it would not be feasible to do so.

Schematics

Component Source

All components used shall be from the team’s A365 library. No components shall be from the Altium content vault, a local library, or any other source.

Template

All schematic sheets shall use Midnight Sun templates. The title block shall be populated using the relevant sheet parameters.

Power Net Naming

Use minimum number of significant digits, always include “V” where the decimal point would go.

Negative nets are prefixed with “N”, positive nets have no prefix.

Ex: 12V, 5V, 3V3, N2V1, 131V

Component Sourcing

New components shall not be sourced if a suitable alternative already exists in our library.

...

LEDs required in high power applications are of the JE2835 series.

Style

Grid

All schematics shall be drawn exclusively on a 100 mil grid for neatness. I will be sad if you use a 50 mil grid.

Power Net Naming

Use minimum number of significant digits, always include “V” where the decimal point would go.

Negative nets are prefixed with “N”, positive nets have no prefix.

Ex: 12V, 5V, 3V3, N2V1, 131V

Decoupling

IC decoupling shall be achieved by a minimum of one 0.1uF MLCC capacitor per power pin. Additional decoupling shall be added if warranted by the application, such as in high power devices. The datasheet will generally have recommended decoupling schemes. It is acceptable to round decoupling cap values to nicer numbers, ie 0.47uF to 1uF. Be weary of excessive capacitance resulting in inrush current.
