Pcb Electrical Symbol. Circuit symbols of electronic components are symbols or drawings or signs or pictogram of electronic components to represent electrical and electronic components and devices schematic diagram of an electronic circuit. The symbol as initially created will represent the generic graphical features of a resistor but not the detailed functions of a specific resistor.
This common graphical standard for schematic symbols was deprecated in 2019 but many of its symbols are still in common usage so engineers would be wise to reference it. When the pcb designer places that symbol onto a schematic the symbol is associated with the specific functional information such as resistance values and tolerances of the desired part. You will see the symbol for a resistor.

These can be done in silkscreening process or anti soldermask processes. Electrical symbols and electronic circuit symbols are used for drawing schematic diagram. Next to the symbol you will also see its value 2 2k. These are done by the fab house and are used to show ul certification numbers ul standards that the pcb conforms to sometimes showing rohs compliance and sometimes even a logo of the fab house.
