What is PCB?
PCB=printed circuit board; It is an important electronic component, the support body of electronic components, and the carrier of the electrical connection of electronic components. Since it is made using electronic printing, it is called a "printed" circuit board.
PCB is the abbreviation of printed circuit board, which is an important electronic component for loading electronic components and a connection carrier for the conduction of electronic components. It is so called because of a printing technique. PCBs are divided into single-layer, double-sided, and multi-layer according to the circuit layer. Typical are 4-layer and 6-layer multilayer PCBs. More complex multilayer PCBs have dozens of layers. It can also be divided into rigid boards, flexible boards and flexible rigid boards. Printed boards have developed from single-layer to double-sided, multi-layer, and flexible boards, maintaining their respective development trends.
What is PCBA?
PCBA=assembly of PCB. Various electronic devices are assembled on the circuit board through a surface packaging process. The next step is box assembly, which is to assemble the assembled PCB and shell to form a finished product. That is to say, the PCB blank board goes through the SMT loading and then goes through the entire process of DIP plug-in, referred to as PCBA. This is a commonly used writing method in China, while the standard writing in Europe and the United States is PCB'A, which is obliquely added. PCBA is a PCB with a patch.
PCBA: Printed Circuit Board Assembly is a term in the electronic processing industry, which mainly refers to the soldering or insertion of various electronic parts, ICs and other materials on the blank circuit board and quality inspection and testing to ensure that it has complete circuit connection performance. The blank board is made according to the customer's PCB file. As a result, there are no electronic components on the whiteboard, just a wide variety of pads. Installing electronic components on the PCB, installing electronic components is SMT processing, that is, soldering the electronic parts on the pads, and then using DIP plug-ins to assist in the processing to complete the entire soldering process.
