Definition

PWB (Printed Wiring Board) is an alternative term for PCB (Printed Circuit Board). PWB emphasizes the board's function as wiring interconnect, while PCB reflects that it's part of a circuit. Usage varies by region and industry - PWB is more common in Japan and among traditional manufacturers. IPC standards use both terms. In practice, PWB and PCB are interchangeable. The term 'printed' comes from the photolithographic process used to create conductor patterns.
