Printed circuit boards are the foundation of nearly all electronic devices, from smartphones and computers to medical equipment and industrial controls. PCB manufacturing involves a series of complex steps to create conductive pathways on a non-conductive substrate, allowing electronic components to communicate and function.
The process originated in the early 20th century and has become increasingly refined with the rise of consumer electronics and miniaturized technology. Today, PCBs are manufactured using techniques like electroplating, etching, and surface finishing to create multilayer boards with tight tolerances and reliable conductivity.
Copper is commonly used for its excellent conductivity, and layers are built up or etched away to form the desired circuit layout. Finishing steps like tin, gold, or nickel plating protect the copper and ensure solderability.
Several key steps in PCB manufacturing require clean, regulated DC power. Electroplating is used to form copper traces and vias, while other steps such as surface finishing and edge plating also depend on precise voltage and current control. Any fluctuations in power can lead to uneven plating, poor adhesion, or defects that affect board performance.

Explore these insights to gain a better understanding of how PCBs power modern electronics and the key considerations in their design and production.
A PCB is a board that connects and supports electronic components using conductive pathways, tracks, or signal traces etched from copper sheets and laminated onto a non-conductive substrate.
PCBs typically consist of a substrate (FR4 is common), copper layers, solder mask, and a silkscreen layer for component labeling.
PCBs are used in consumer electronics, automotive, aerospace, medical devices, telecommunications, and more.
