20231212 - Altium Component Symbol creation

Symbol creation:

  • Be careful with symbol creation wizard because it does strange things with the grid
  • Pin labeling: “1”, “2”, “3”, etc. NO “01”, “02”. If letters, all caps “A”, “B”, “C”.
  • Pin length: 100 Mills
  • Pin spacing: 100 Mills
  • The symbol ports needs to allign with 100 Mills grid.
  • Always do Edit > Align > Align to grid
  • The symbols should be created for the series. That means that the series of WCAP-ASLI should be one symbol, and it should change the footprint of it. It is easier this way to make modifications after in production.
  • In some cases, like super standard resistors or capacitor, is enough to chose the next:
    • Capacitance
    • Rating
    • Tolerance
    • (Optional) Dielectric
  • If you dont want to be in the boom select in Type to not go to BOM
    • Standard - components that possess standard electrical properties, are always synchronized between the schematic and PCB (the footprint, pins/pads and net assignments must all match), and are included in the BOM. An example is a standard electrical component, such as a resistor.
    • Mechanical - components that do not have electrical properties, are not synchronized (you must manually place them in both editors), and are included in the BOM. An example is a heatsink.
    • Graphical - components that do not have electrical properties, are not synchronized (you must manually place them in both editors), and are not included in the BOM. An example is a company logo.
    • Net Tie (In BOM) - components that are used to short two or more different nets together, are always synchronized between the schematic and PCB (the footprint, pins/pads and net assignments must all match), and are included in the BOM. They differ from a Standard component in that connectivity created by copper within the footprint is not checked; it is this copper that allows the nets to be shorted. Note: enable the Verify Shorting Copper option in the  Design Rule Checker dialog to verify that there is no unconnected copper within the component.
    • Net Tie (No BOM) - components that are used to short two or more different nets together, are always synchronized between the schematic and PCB (the footprint, pins/pads and net assignments must all match), and are _not _included in the BOM. They differ from a Standard component in that connectivity created by copper within the footprint is not checked; it is this copper that allows the nets to be shorted. Note: enable the Verify Shorting Copper option in the  Design Rule Checker dialog to verify that there is no unconnected copper in the component.
    • Standard (No BOM) - components that possess standard electrical properties, are always synchronized between the schematic and PCB (the footprint, pins/pads and net assignments must all match), and are not included in the BOM. An example is a testpoint component that you want to exclude from the BOM.
    • Jumper - components that are used to include wire links in a PCB design, for example, on a single-sided PCB that cannot be fully routed on one layer. For this component type, the component footprint and pins are synchronized between the schematic and PCB but the net assignments are not, and the component is included in the BOM. As well as selecting this option at the component level, both of the pads in the component must have their JumperID set to the same non-zero value. Jumper type components do not need to be wired on the schematic; they only need to be included on the schematic if they are required in the BOM. If they are not required in the BOM, they can be placed directly in the PCB where the Component Type is set, the JumperIDs are set, and the Nets manually assigned for the pads.

Footprint creation:

  • Put point to mark pin 1
  • Pin labeling: “1”, “2”, “3”, etc. NO “01”, “02”

The steps are kinda these:

  • Create a symbol by your own or from the manufacturer
  • Add the parameters from Ciiva
  • Add the footprint from the manufacturer

Pin length: 100mils
