PCB Section Analysis Solutioin - Metallurgical Microscope
Test requirements:
For PCB board, after slicing, green oil, copper thickness, etc. are used to determine the quality and analyze the quality abnormity, inspect the quality of circuit board, PCBA welding quality inspection, PCBA welding quality inspection, PCBA welding quality inspection.
Find out the cause of failure and solutions, evaluate the process improvement, as the basis of objective inspection, research and judgment.
The outer layer quality or poor appearance can be judged by optical detector or visual inspection;
But for the quality confirmation of the inner layer or hole after pressing, it is necessary to determine the quality by slicing and make a preliminary analysis of the causes of the defects
Slicing analysis is an important technology for PCB / PCBA failure analysis. Slicing quality will directly affect the accuracy of failure location confirmation.
Solution:
Material analysis metallographic microscope is suitable for metal material, structure analysis. The coaxial vertical lighting system is used to eliminate stray light,
Thus, the contrast (contrast) and clarity of imaging are greatly improved. With measurement software, the thickness measurement and metallographic analysis software can effectively analyze the material condition;
