There is a saying that goes well:; Overcoming prejudice is a form of courage that can bring you closer to the truth;, The editor thinks it's very reasonable. The user who had been in contact for two years finally overcame the problem; Prejudice;, Accepting the suggestion of the editor, we updated the previously used metallographic sandpaper to American QMAXIS silicon carbide metallographic sandpaper. After application, we found that the difference between the two is really significant! What's going on?

The user is a young metallographic engineer, who is particularly kind, diligent, meticulous, meticulous, and skilled. Due to being an electronic product production enterprise, sample preparation is the same every day, with roughly the same materials, quantities, and technical requirements. Metallographic sandpaper has always been used in the grinding step of the sample process, and the amount of sandpaper used is also particularly large, which is the main part of sample preparation cost consumption.


With the technological innovation needs of the R&D department, sample preparation is now different from the past. With changes in materials and upgrades in technical requirements, the quality and quantity of sample preparation based on the original level can no longer keep up. After understanding this situation, the editor suggests that replacing imported metallographic sandpaper with high removal rate and more wear-resistant material during the grinding stage can not only accelerate sample preparation speed, but also improve the quality of sample preparation.

At first, she always felt that using imported metallographic sandpaper was too expensive, worried about not grinding it well, and added a lot of costs, making it difficult to explain Various concerns. Ah, changing one's mindset is not an easy task. The editor understands it very well, but there are always ways.


After communicating with the application engineer of pulse detection, the editor took out P180, P320, and P600 grit size metallographic sandpaper with a diameter of 10 inches from the QMAXIS metallographic sandpaper and sent it to the user's laboratory for her to try and see the effect before deciding whether to replace it. During the trial process, all experimental data was recorded, and after repeated trials, a summary and comparison were made. The results are as follows:

Material type

Sandpaper model

Grinding speed/grinding time

Sample surface

Original metallographic sandpaper

QMAXIS Metallographic sandpaper

Original metallographic sandpaper

QMAXIS Metallographic sandpaper

Printed circuit board

P180

260rpm/1.3min

ordinary

very good

P600

260rpm/3.5min

260rpm/1.3min

After experimental comparison, users were surprised. They thought there wouldn't be much difference, but the result was that the sample preparation speed could be increased by at least twice, and the surface quality of the sample was also very satisfactory.


The user said: I didn't expect that a piece of QMAXIS metallographic sandpaper could be equivalent to the 3-5 pieces I used before. Overall, the direct cost is similar and acceptable. The important thing is to improve work efficiency and sample preparation quality, so that R&D engineers will no longer be tempted by the stars in their eyes and the heat in their heads. In the future, all samples with high technical requirements will be prepared using QMAXIS metallographic sandpaper imported from the United States, with confidence in mind!

Create a way for users to overcome inherent limitations; Prejudice; The conditions to help her choose a good metallographic sandpaper can help her quickly prepare samples! After this incident, the editor has gained a deeper understanding of the work. In fact, overcoming inherent knowledge and updating concepts is the key. Some things may seem very difficult, but if you change your mind, it may turn out to be a mystery. Do you agree with friends who saw the article?
