In electronic manufacturing terminology, the names of circuit boards are clearly distinguished based on whether they have electronic components soldered on them, and these names are widely used in industry communication, procurement, and production management. An empty PCB board—one that has no electronic components, connectors, or any other parts attached—is officially called a "bare PCB" or simply a "PCB blank." This type of board only includes the insulating substrate, copper traces, pads, vias, and other structural elements that are etched or printed during the PCB manufacturing process. It is a raw material in the electronics industry, and its appearance is usually a flat board with a green, black, or other colored solder mask (the protective layer covering the copper traces), with exposed copper pads where components will be soldered later. Bare PCBs are often supplied by PCB manufacturers to assembly factories, which then add components to form functional boards.

A board that has had electronic components soldered onto it, regardless of the assembly method (whether SMT or DIP), has several common names, the most widely used being "PCBA" (Printed Circuit Board Assembly). PCBA is the standard term in the industry to describe a PCB that has undergone component assembly and soldering, forming a functional electronic circuit. Unlike a bare PCB, a PCBA is a semi-finished or finished product that can perform specific electronic functions—for example, a PCBA for a power supply module can convert AC voltage to DC voltage, while a PCBA for a sensor module can collect and transmit environmental data.

In addition to PCBA, there are some alternative names used in specific scenarios, but they all refer to the same type of board with soldered components. For instance, it may be called an "assembled PCB" or a "populated PCB" (since components are "populated" onto the PCB). In some contexts, especially in consumer electronics, it may also be referred to as a "circuit board assembly" (CBA), but PCBA remains the most universal and standardized term. It is important to note that these names are not interchangeable with "PCB"—a PCB is always the bare substrate, while any board with soldered components is a PCBA or one of its equivalent terms, emphasizing the completion of the assembly process.
