Semi-quantitative method for judging brittleness and ductility of copper-clad plate

The present invention provides a semi-quantitative method of evaluation of the brittle-ductile copper clad laminate, comprising the following steps: Step 1. providing a sample; Step 2. providing fixing means; Step 3. The sample is placed in the sample holder is placed, and adjusting the reference standard frame, such that the marks on the sample off all in standard reference frame; step 4 with the camera image; step 5. providing a graphical analysis tool; step 6. image analysis using a graphical analysis tool, the comparative sample and the size of the area off the mark shape mark off , obtained determination result. By creating and securing means for photographing the sample holder is placed outside environment to the fixed camera shooting, the shooting process to eliminate the influence caused by calculation of the area, and calculate the actual area of ​​the white region Chula marks and scratches off the scale factors, its simple and convenient operation, to judge according to the brittle-ductile "cross" shape off the mark area size, quantitative evaluation CCL ductile brittle, more accurate evaluation, in particular, can be accurately judged marks off an area close to the CCL.
