Client Setup
Some things to help you get started
Below is a download of our standard settings file. This automatically sets up your local client settings, such as default templates, color schemes, etc.
This file is also available directly in the vault at: X

Deprecated. We now embed 3D models directly into footprints.footprints.
Saving Items
Projects, components, symbols, and everything else in Altium are all managed in the version control system. Anytime you save to server you will be prompted to enter a commit comment.
You must add a note briefly detailing changes you made on all commits!
Components
Requirements for component files. See https://nerdocs.atlassian.net/wiki/spaces/NER/pages/118718470/Vault+Guidelines#Symbols.1 and https://nerdocs.atlassian.net/wiki/spaces/NER/pages/118718470/Vault+Guidelines#Footprints.1 for the symbols and footprints you embed!

Symbol Layout
Symbols should use imperial spacing at 100 mils.
If a more detailed symbol isn’t available, footprints should be implemented using the Altium default yellow rectangle with “small” red outline.
Pins
Pins should be spaced by one 100 mil grid spacing.
Pin designators should be hidden and pin names should exactly match the datasheet (with the exception of characters that Altium doesn’t allow).
Pin arrangement can be either matching the physical layout or optimized for schematic routing (place pins as needed to avoid messy wires).
All pins must be passive type.
Designators
Utilize common designators for symbols. The hard-set definition we use is Appendix F of IEEE-315:
...
The right side column is what we utilize, when applicable.
All designator letters should must be followed by “?”, as this is the wildcard for auto-generating designators. For example “D?” for diodes, “J?” for connectors, “R?” for resistors.

...
Solder mask relief must be set to “Rule.” Exceptions should only be made if a component datasheet requests exact values.
Plated Through Holes
Annular ring (the difference in radius between pad radius and hole radius) should be 12 mils / 0.3 mm. Fabricators specify a smaller size which we can use, but we recommend this size for ease of hand solderability.
This means you should take hole size (diameter) and add 0.6mm. See https://www.worthingtonassembly.com/plated-thru-hole-size for more.
Given a pin diameter, the hole size should be determined by adding 0.2mm.
Mounting & GND Pads
If a component requires additional pads that are not regular electrical connections, they must be defined as “GND” or as “MNT” dependent on purpose of the pad. They may be MNT1, MNT2, etc to keep unique identifiers.
...
This can be achieved using the circle tool with a width of 5 10 mils / 0.125 25 mm and radius of 10 5 mils / 0.25 125 mm.
Pin one ideally is also indicated via pads with a rectangular/square pad (with the other pads being ovular/circular). This is most typical in through-hole components.

There are tools to rapidly update the board outline. See https://nerdocs.atlassian.net/wiki/spaces/NER/pages/156205064/PCB+Layout#Update-Board-Outline.
