As PCB factory china knows that，PCB Mircosection is mainly used to check the internal wiring thickness, layers of the PCB, the size of the through-hole and the quality observation of the through-hole.

It is also used to check the internal cavity of the PCBA solder joint, the interface bonding condition and the wetting quality evaluation. The quality of the PCB, the occurrence and solution of problems and the evaluation of process improvement which need mircosection as the basis for objective examination, research and judgment. 

PCB Mircosection is one of the important analytical methods in PCB industry, which is often used for quality determination or quality abnormal analysis.
