What is the difference between PCB and PCBA?

November 01, 2024

1、 What is PCB?

PCB: refers to a printed circuit board, which is an important electronic component and a support body for electronic components. It is mainly used to connect and support electronic components. It is also a provider of electronic component circuit connections. It is a blank circuit board without any electronic components soldered. It is made of non-conductive materials (such as glass fiber, epoxy resin, etc.) as the substrate, and copper foil is laid on top to form conductive lines for connecting electronic components. Integrated circuits are a type of electronic component that includes electronic components (such as transistors, capacitors, etc.) and the circuits that connect them. Integrated circuits, commonly known as chips, are manufactured on a single semiconductor chip and integrate multiple electronic components and circuits.

According to the different layers, PCBs can be divided into single-layer boards, double-layer boards, and multi-layer boards. For example, PCB not only provides conventional single-sided and double-sided boards, but also can produce complex high multi-layer boards to meet the needs of different customers.

2、 What is PCBA?

PCBA: Refers to soldering electronic components onto a PCB to form a complete circuit system. PCBA is the finished product of PCB processing, which includes the assembly and soldering process functions of electronic components. PCBA contains the PCB and all necessary electronic components that work together to achieve the predetermined functions of the circuit board. Simply put, it is a series of process flows consisting of SMT surface mount processing, DIP plug-in processing, and PCBA testing, abbreviated as PCBA.

After obtaining the PCB as raw material, manufacturers solder and assemble the required electronic components such as IC, resistors, capacitors, crystal oscillators, transformers, etc. on the PCB board through SMT or plug-in processing. After high-temperature heating in the reflow soldering furnace, mechanical connections between the components and the PCB board are formed, thus forming the PCBA.

Therefore, PCB is a bare circuit board with printed conductive lines and installation positions for components, while PCBA refers to the process of assembling components onto PCB, completing soldering and connection, thereby forming a usable electronic product. PCB is the foundation of PCBA, which transforms circuit boards into complete products with functionality and performance.

Choosing the quality and performance of PCB and PCBA is crucial for the reliability of electronic products. Understanding the differences between PCB or PCBA suppliers can help to better develop production plans, thereby improving product quality and efficiency.

PCB is a flat circuit board filled with air or other insulating materials, which can realize the circuit connection and mutual signal transmission of electronic components, and has a low cost of use; PCBA adds a soldering process for components on the basis of PCB, which can realize circuit board assembly and practical applications.

PCBs and integrated circuits play different roles in the field of electronics, and their functions and uses also differ. PCB is a printed circuit board, which is the basic structure of electronic devices. It is mainly responsible for transmitting electrical signals between circuit boards. They have not yet been equipped with electronic components, so some people also call them light boards. Integrated circuits are miniature electronic devices that use special processes to integrate multiple electronic components, such as transistors, resistors, and capacitors, onto a single chip to perform specific functions.

Both PCB and PCBA are indispensable components of the electronics industry. The rise of SMT technology combined with the assembly process of PCBA indicates that the electronics industry will develop towards higher efficiency and intelligence. In the future, both will work together to shape a more efficient and environmentally friendly electronic world.
