2. What Are Circuit Boards?

Circuit boards, also known as printed circuit boards (PCBs), are essential components in virtually all electronic devices. They serve as a platform for connecting electronic components and providing pathways for electrical signals. A circuit board consists of a non-conductive substrate, typically made of fiberglass or epoxy resin, upon which conductive pathways are etched or printed. These pathways allow for the effective transmission of electrical signals between components, ultimately enabling the device to function.

3. The Evolution of Circuit Board Technology

The journey of circuit board technology has been remarkable, marked by significant advancements that have transformed the electronics landscape.

3.1 Early Beginnings of Circuit Boards

The inception of circuit boards dates back to the early 20th century, when engineers began using hand-wired components to create simple electronic circuits. The first true circuit boards emerged in the 1930s, designed to simplify and standardize the assembly of electronic devices. As technology progressed, the introduction of printed circuit boards revolutionized manufacturing processes, reducing costs and increasing reliability.
