PCB is an abbreviation of Printed Circuit Board, which is an important electronic part to load electronic components and connection carrier of electronic components conduction. Why called is due to fabrication with a printing technology.

PCB is classified as single layer, double-sided and multilayer in terms of circuit layers. Multilayer PCB with 4-layers and 6-layers is typical. More complex multilayer PCB has up to dozens of layers. It is also can be divided into rigid board, flexible board and flex-rigid board. High Quality PCBs china evolved from single layer to double-sided, multilayer and flexible board, retaining respective development tendency.

PCBA: PCB assembly Printed circuit board

Circuit board assembly is a term of electronic processing industry, mainly refers to a variety of electronic parts, IC ect. materials welded or inserted in a blank circuit board and quality inspection and test, to ensure that it has a complete circuit connection performance.

Blank board is pcb manufacturer in china on the basis of customer PCB file. Therefore, there isn't any electronic parts on the blank board, but a variety of pads. After the mounted plug, mounted that is SMT, which means that electronic parts are welded on the pad, then need to use the DIP plug-in auxiliary processing, complete the whole welding process.
