You will need to be careful to verify that the existing footprint in your design library matches the mechanical dimension of the component according to its datasheet. In practise, you will already have most of the footprint available and you should need to create only few additional footprints for a new design. Footprints can be reused in the same board several times. Footprint is a physical view of theĬomponent that includes the holes through your board or pads for surface mount components. For each component, you have to create a footprint. You must get the physical part in hand to verify pin number 1 orientation and dimensions.Ģ. Interestingly, you will be devoting most careful about the electrically simplest component - connectors. Resistors, Capacitors,Inductors, Ferrite Beads In actual practice following are the main categories of the components used
Once you have a list, collect the datasheets and look at the suggested footprints (that is, the hole sizes or pads) in those documents. Select the components (capacitors, sockets, etc.) you will be using on your board. Others may like to get a general view of the design process which is follows:ġ.
