altium update pcb footprint from library

The created circuit board footprint should always match the component physical dimensions or else it will not align properly with the pads. Only if it is not available, we will have to create one on our own referring to the datasheet of the component, while designing a circuit board. Most of the time, the PCB footprint creation of standard packages are available in the PCB library of the design software. The footprint or land pattern is an arrangement of plated copper pads or through-hole plated pads on a PCB on which a component is soldered. Be it surface-mount, through-hole, or ball grid array (BGA), a land pattern is mandatory for PCB assembly. Irrespective of the type of component, there should be a footprint so that it can be soldered to the board at a later stage. The footprints on the board are interconnected using traces and vias. It gives an idea about the component placement and the trace locations. This footprint connects a component to the circuit board both physically and electrically. It is also called the land/pad pattern and resembles the physical dimensions of the component. PCB footprint creation is the arrangement of plated pads where a component is supposed to be soldered.
