What is the difference between PCB and PCBA [Copy link]

 

PCB (Printed Circuit Board) and PCBA (Printed Circuit Board Assembly) are two related but different concepts. The differences between them are as follows:

1. PCB (Printed Circuit Board) :

   • PCB is a substrate used to connect and support electronic components. It is made of conductive material (usually copper foil) with circuit patterns printed on it for connecting various electronic components.
   • A PCB is usually composed of multiple layers of sheet materials, including a conductive layer, an insulating layer, and a cover layer, wherein a circuit pattern is printed on the conductive layer.
   • As one of the basic components of electronic products, PCB is used to support and connect various electronic components and build circuit functions.

2. PCBA (Printed Circuit Board Assembly) :

   • PCBA refers to the installation and soldering of various electronic components on PCB to form the final electronic product assembly. PCBA includes not only the PCB itself, but also the electronic components installed on the PCB.
   • PCBA usually includes the following steps: component procurement, PCB surface mounting, soldering, testing and debugging, etc. Through these steps, various electronic components are installed on the PCB and ensure that they can work properly.

In general, PCB refers to the printed circuit board itself, while PCBA refers to the installation and soldering of electronic components on the PCB to form the final electronic product assembly. PCB is part of PCBA, which includes the PCB and the electronic components installed on the PCB.
