What Is a Double Sided PCB

A Double Sided PCB (also called 2-layer PCB) has copper conductive layers on both sides of the insulation substrate. Plated through holes (PTH) connect two sides for better routing and density.

Key features include higher component density, flexible wiring, improved signal integrity, and wider usage than single-sided PCBs.
