Is PCBA an integrated circuit (IC)?

PCBA is not an integrated circuit. There is a big difference between PCBA and integrated circuit. PCBA is a motherboard with many electronic components arranged on it, and the integrated circuit is just an electronic component on the PCBA board.
 

First, what is PCBA?

PCBA is Print Circuit Board Assembly. PCBA refers to the whole process of PCB SMT and DIP plug-in processing process for PCB bare board. PCBA is just a semi-finished product, such as a motherboard on a computer. It usually needs to be packaged with a casing to become a finished product.

Second, what is an integrated circuit?

Integrated circuit, also known as a chip or an IC. An integrated circuit is an electronic component that contains transistors, resistors, capacitors, inductors, etc., and has the required circuit functions. It is a component on the PCBA.
Third, the difference between PCBA and integrated circuits.

Integrated circuit is just an electronic component that is distributed across the PCBA board and can only perform a single function.

PCBA is a finished circuit board that can realize certain electrical functions, which is covered with various electronic components.

In general, integrated circuits are individuals, PCBA is a whole, and integrated circuit is an integral part of PCBA. They are not the same thing.
