The History and Evolution of the Printed Circuit Board

The printed circuit board was introduced to us nearly 90 years ago, and along the way, it has seen massive improvements. As technology has progressed and evolved, these boards have continued to become more sophisticated. A printed circuit board or a PCB connects electrical components by conductive paths or tracks that have been printed or etched on the board.  Check out more about What a Printed Circuit Board Is and what it is used for here.

What is a PCB?

PCB stands for Printed Circuit Board.

A printed circuit board mechanically supports and electrically connects electronic components or electrical components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.

Printed circuit boards (PCBs) are thin boards made from an insulating material, with a metal coated surface. Etches are made in the metal with acid to create pathways for electricity to travel among various components which are surface mounted on the board with solder.
