The power supply section should be kept separate from the analog and digital parts, especially if they use signals with high switching frequencies. For example, power management ICs (PMICs) should be grouped in the same power management section, along with converters, LDOs and similar devices that develop a fair amount of heat and generate high currents. 1 - Group components by functionĬomponents that have similar functions should be grouped together. The following are the main rules that help PCB designer to achieve optimal placement of the components. Rules for the placement of components on the PCBĬomponent placement is one of the very first stages of PCB design and must be approached with the utmost care in order to avoid costly rework and waste of time. It should therefore come as no surprise that the component positioning phase generally requires more effort than routing. For example, placing analog and digital components without adequate separation leads to almost certain corruption of some signal. The correct positioning of the components on the PCB is essential, as it avoids the arising of problems that could compromise the manufacturability, functionality, duration and maintenance of the printed circuit board. ![]() The increase in the operating frequencies of the signals requires high precision in the layout in order to avoid power and signal integrity issues, minimizing the chance of generating electromagnetic interference and improving heat dissipation. This complexity is due on the one hand by the market demand for increasingly rich and advanced features, on the other by the need to create ultra-small PCBs as required by the latest generation devices. Over the years, the layout of printed circuit boards has become more and more complex, with an increasing density of components.
