The PCB or printed circuit board plays a significant role in the world of electronics helping in providing pathways while supporting the components mechanically. Due to the different steps in the process, the board is also referred to as etched or printed wiring board. The process of printed circuit board assembly involves several individual steps starting from etching or patterning to chemical etching, lamination, drilling and then plating the exposed conductors. The printed circuit assembly actually takes place once the circuit board is completed.

In the assembly process, the board is populated with various electronic components using several different types of soldering. A lot has changed in the world of printed circuit board design as well cutting down not just on the time required but also in the amount of material that is used up. The PCB layout is now efficiently done using advanced software. The designing process involves capturing the schematic details of the circuit for which various tools are available. It is also important to accurately draw the interconnectivity information about the nodes in the circuit and the pin connectors.

One of the more important processes of the PCB design is to first roughly locate where individual components have to be placed on the board and soldered. This will give a good idea of the space requirements and the circuitry. Based on the number of components, the number of layers needed on the board is also determined. One has to work on routing information as well so that the various connections between components can be traced accurately. Thus, a lot of steps go into achieving a completed board that performs as per expectations. There could be challenges with routing and other steps when there is a large number of electronic components which are being used on the circuit board.
