The difference between PCB and PCBA

What is PCBA?

PCBA (Printed Circuit Board Assembly) circuit board assembly is a term in the electronics processing industry, mainly refers to various electronic parts, ICs and other materials soldered or inserted on a blank circuit board and quality inspection and testing to ensure that it has the performance of a complete circuit connection. It is a circuit board obtained after printing solder paste on the PCB and then installing various components such as resistors, ICs, capacitors and transformers according to the purpose and desired characteristics of the board. PCBA is usually heated in a reflow oven to create a mechanical connection between the PCB and the components.

What is PCB?

PCB (Printed Circuit Board), also known as printed circuit boards, is the support body of electronic components, but also the carrier of the electrical connection of electronic components. PCB has many types, single-sided, double-sided, multi-layer.

The difference between PCB and PCBA: PCB is short for printed circuit board, is an important electronic component loaded with electronic components, is the connection carrier for electronic component conduction. PCB is divided into single-sided, double-sided and multi-layer by circuit layers. Typically 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, multilayer and flexible boards, maintaining their respective trends.

Blank boards are made according to customer PCB files. Therefore, there are no electronic components on the blank board, only a variety of pads. mounting electronic components on the PCB, mounting electronic components is SMT processing, that is, electronic parts soldered on the pads, and then the need to use DIP plug-in auxiliary processing to complete the entire welding process.
