About the difference between PCBA and PCB where?

I believe that many people for PCB circuit boards, SMT SMD processing of these electronics industry-related terms, is not unfamiliar, these are often heard in daily life, but many people do not know much about PCBA, often confused with PCB. So what is PCBA? What is the difference between PCBA and PCB?

The difference between PCBA and PCB:

From the introduction of the above can be known, PCBA refers to a general process, can also be understood as a finished circuit board, PCB board on the process are completed before counting the PCBA

pcd refers to circuit boards; PCB is divided into double 6 layers 4 layers 8 layers of the motherboard;

and PCB refers to an empty printed circuit board with no parts on it.

PCBA That is, the PCB empty board through the SMT on the pieces, and then after the DIP plug-in the entire process, referred to as PCBA.

The common point is to weld some on the motherboard in the pcb board paste resistors, ic, chip, capacitor

The modern processing industry has a high degree of automation. Minghua avionics full smt mounter using machine intelligence to replace manual welding; can realize accurate and fast detailed processing.
