In order to create a printed circuit board, schematics must be available. High frequency PCB schematics serve as the blueprint of how a printed circuit board will operate. A PCB schematic is a general overview of how the components of a circuit board relate to each other, helping engineers understand how components, circuits, and connections relate to each other. Schematics based on hierarchies also show how each schematic operates in relation to others in a complete PCB.

A High frequency PCB schematic should be created before handling PCB footprints, as it serves as a guide that shows the current and layout of a circuit. Beginning with footprints can lead to issues in electrical conductivity, as it leads to circuits without the proper room or stability. The schematic illustrates components and symbols that are associated with the footprints, which serve as a visual map of a board.

High frequency PCB footprints, or land patterns, are shapes that contain critical information for the function of a printed circuit board. It gives an accurate impression of the size of a component as it sits on a board. If they are not located in the correct position, the part may not solder correctly, and if the outline is incorrect, parts may be placed too close together for assembly. Every footprint should have a reference designator containing attributes such as category, value, manufacturer, and other variables important to the fabrication and assembly process.
