Overview

PCB circuit board slicing analysis solution testing requirements: After the PCB board is sliced, quality judgment and quality abnormality analysis of green oil, copper thickness, etc. are carried out, the quality of the circuit board is inspected, the quality of PCBA soldering is tested, the causes and solutions of failure are found, and process improvement is evaluated as the basis for objective inspection, research, and judgment

Product Details

Solution for PCB circuit board slicing analysis

Testing requirements:

After slicing the PCB board, perform quality judgment and quality anomaly analysis on green oil, copper thickness, etc., inspect the quality of the circuit board, and perform PCBA soldering quality testing

Identify the causes and solutions of failures, evaluate process improvements, and use them as the basis for objective inspection, research, and judgment.

For poor quality or appearance of the outer layer, it can be judged through optical inspection or visual inspection;

But for the quality confirmation of the inner layer or holes after compression, it is necessary to conduct quality judgment through slicing and make preliminary analysis of the causes of defects

Slice analysis is an important technique for PCB/PCBA failure analysis, and the quality of slices will directly affect the accuracy of confirming the failure site.

Solution:

Material analysis metallographic microscope is suitable for metal materials and structural analysis. Adopting a coaxial vertical illumination system effectively eliminates stray light,

This greatly improves the contrast (contrast) and clarity of imaging. Paired with measurement software, it can effectively analyze the material condition for thickness measurement and metallographic analysis software;
