Greater circuit density: Double-sided PCBs is often included more components that efficiently raise the circuit's density. It's far better to get some components linked to the bottom aspect instead of all on a person facet. Power and ground planes are committed layers in a very PCB that provide minimal-impedance paths https://double-sidedimmersiongold95937.blog-gold.com/38742583/facts-about-four-layer-tin-spraying-module-power-pcb-revealed
