History of Printed Circuit Boards: Inception to Now

The Evolution and Significance of Printed Circuit Boards (PCBs)

In 1903, Albert Hanson, a visionary from Germany, pioneered the concept of the printed circuit board (PCB). He filed a groundbreaking patent with a design that forms the foundation of today’s PCBs, specifically for telephone systems. His invention featured a multi-layer insulating board with through-hole construction and conductors on both sides.
