However a library for all the devices used will be built up within the PCB layout design system. Typically several devices may share the same footprint, so this information does not have to be entered for each component part number. This will include the footprint for the printed circuit board pads, any drilling information, keep out areas and the like. In order that components can be incorporated into the PCB design they must have all the relevant information associated with them. This can take into account aspects such as the proximity of devices that may need to communicate with each other, and other information pertaining to any RF considerations for example. Once a rough estimate has been made of the space and approximate locations of the components, a more detailed component layout can be made for the PCB design. This will enable decisions about the number of layers needed in the board, and also whether there is sufficient space to contain all the circuitry may need to be made. PCB design showing components and tracks Initial PCB component placementД«efore proceeding with the detailed PCB design and layout, it is necessary to gain a rough idea of where components will be located and whether there is sufficient space on the board to contain all the required circuitry. The netlist is the interconnectivity information and it essentially the component pins and the circuit nodes, or nets, to which each pin connects. With the schematic capture complete the electronic design of the circuit is contained within the file and can be converted to what is termed a 'netlist'. For applications such as RF circuit design simulation of the circuit will enable the final circuit to be optimised more without building a prototype. Some packages may be able to interface to simulation packages. In addition to purely performing the schematic capture, simulations of the circuit may be undertaken at this stage. This may form part of the PCB design suite, or it may be an external package whose output can be exported in a suitable format. Circuits may be entered into a schematic capture tool.

This may be achieved in a variety of ways.

The first stage in the development of a PCB design is to capture the schematic for the circuit. The ability to undertake simulations is becoming an increasing requirement with the speeds of digital boards increasing, and radio frequency designs reaching ever higher frequencies. Simulations, complex routing, and many more facilities are available.

Budget, or even free software provides the basic functions, whereas the top end packages enable many more facilities to be incorporated into the design. The PCB software capability varies considerably. The old PCB design process of using tape placed on a master drawing sheet are long gone, although it is possible this may still be done in a number of very limited cases. Typical complicated PCB design PCB design equipmentДЇor commercial development programmes there are may CAD, computer aided design packages available that are needed as a result of the complexity.Д®ven for the student and hobbyist there are many very good packages that are either free of can be obtained for a modest cost. The PCB layout and design has a major impact on the way in which a circuit work, and therefore if the printed circuit board is designed in an effective way, then the circuit will perform more reliably and within its specification.
