What is the differrence between PCB and PCBA?
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.
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.
