What is the difference between an IC and a PCBA?

November 01, 2024

1、 What is an integrated circuit?

Integrated circuits, also known as ICs or chips, are miniature electronic devices or components. Through a certain process, the required components and wiring of a circuit, such as transistors, resistors, capacitors, inductors, etc., are interconnected and fabricated on a small or several small semiconductor chips or dielectric substrates, and then packaged in a shell to form a microstructure with the desired circuit function, where all components are structurally integrated as a whole. And its advantages are: small size, light weight, long service life, low cost, good performance, high reliability, few lead wires and welding points, easy for large-scale production, etc.

2、 What is PCBA?

PCBA is the entire process of assembling printed circuit boards, which involves surface mount technology (SMT) and DIP plug-in processing of PCB blanks. PCBA is the finished form of PCB, which has completed the soldering and assembly of components.

3、 The difference between integrated circuits and PCBA

Integrated circuits generally refer to the integration of chips, such as the chips on computer motherboards and the internal structure of CPUs, all of which are called integrated circuits. Printed circuit boards refer to commonly seen circuit boards, and there are also printed and soldered chips packaged on circuit boards. Integrated circuits (ICs) are soldered onto PCB boards; PCB board is the medium for integrated circuits (ICs). PCB board is a printed circuit board. Printed circuit boards are almost always produced on the edges of every electronic product. If there are electronic components in some machine equipment, printed circuit boards are all embedded on PCBs of different sizes. The key function of a printed circuit board, apart from fixing various small parts, is to establish electrical connections between the various components on top. Simply put, an integrated circuit is a general power circuit integrated onto a chip. It is a whole, and once its internal structure is damaged, the chip is also damaged. PCB can be said to be capable of soldering components on its own, and if it is damaged, the components can be replaced.

Integrated circuits (ICs) can be divided into three categories based on their functions and structures: analog ICs, digital ICs, and mixed signal ICs. According to the manufacturing process, it is divided into semiconductor integrated circuits and film integrated circuits (thick film integrated circuits and thin film integrated circuits). In terms of application areas, IC application areas can be divided into standard integrated circuits and application specific integrated circuits.

PCBA is a combination of hard brushed circuit boards and assembly, which can run through the entire production process of SMT on PCB blank boards, and then pass through DIP plugins. It mainly involves installing electronic components onto a printed circuit board and connecting them to the board through soldering or other methods to form a complete circuit. PCBA includes the process of assembling various electronic components (such as transistors, diodes, resistors, etc.) onto a printed circuit board.

Integrated circuit is just an electronic component distributed on PCBA board, which can only achieve a single function.

PCBA is a finished circuit board that can achieve certain electrical functions, covered with various electronic components, and can be directly used after being packaged in a casing.

In general, electronic components in PCBA include ICs, which may involve installing IC chips onto printed circuit boards during the PCBA assembly process. IC is the core of computer chips, microcontrollers, and other electronic components, while PCBA assembles these ICs and other electronic components into a complete circuit board. IC is just an individual, an electronic component on the PCBA board. It is a component of PCBA. The process of soldering IC onto PCB board constitutes PCBA. With the development of technology, ICs are moving towards miniaturization, becoming increasingly powerful and widely used in various fields.
