Schematics design step is, for me, the most important one of the development process as it defines the circuit. Also it's in this step that the foundations are set for an efficient and cost effective production.
One thing that I found to be very useful is to enrich the component information with the following fields:
Populating these fields for all components in the schematics facilitates the exporting of a comprehensive Bill Of Materials (BOM) and the costing of the circuit. To add component information fields to the eeschema template do the following.
Open the eeschema and navigate to Preferences->Schematic Editor Options.
Select the Template Field Names tab.
Click Add.
One thing that I found to be very useful is to enrich the component information with the following fields:
- Mnf - Name of the manufacturer
- Mnf PN - Manufacturer part number
- PN - My part number / reference for the component
- Sup1 PN - Supplier 1 part number
- Sup2 PN - Supplier 2 part number
- Alt PN - Alternative components part numbers
- Unit Price 10 - Unitary price for purchase quantities of 10
- Unit Price 100 - Unitary price for purchase quantities of 100
- Notes - Any note or comments I may want to include in the component information

Now insert the name of the field you want to create in the Name text box. Optionally insert a default value for that field in the Default Value box.
You can add as many fields as you want, so do not limit yourself to my suggestions and customize the "metadata" to be the best fit for your needs.
