Evolution of Circuit Boards in PCB Technology

1. Circuit boards, or PCBs, have a rich history spanning over a century, primarily focusing on layout design.

2. The key benefit of circuit boards lies in their capacity to reduce wiring and assembly errors significantly, leading to improved automation and productivity.

3. PCBs come in various forms based on layers, such as single-sided, double-sided, four-layer, six-layer, and complex multilayer types.

4. The nomenclature of PCBs can be perplexing since they are not standalone end products. For example, a computer’s main circuit board is known as a “motherboard” rather than just a circuit board.

5. While motherboards incorporate circuit boards, they are distinguished differently in the industry. When integrated circuits are affixed to a board, it may be termed an “IC board,” distinct from a standard printed circuit board.

6. When we mention a printed circuit board, we typically refer to a bare board without components attached.

7. Single-sided boards represent a fundamental configuration in PCB technology.
