1. Test results
I just received this bottle of the potion to remove the copper oxide layer, and I will test its effect on the cleaning of copper clad laminates below. The test was carried out using a single-sided copper clad laminate with an oxide layer on the surface. Check out the effects of this rust removal potion. Dip a small amount of the potion with toilet paper, and you can see that the potion is yellow. The copper clad laminate is then scrubbed. Being able to see has a certain effect. The surface of the copper clad laminate is shiny. However, it was felt that the oxide layer was not removed fast enough. The following is a comparison of the effects of hydrochloric acid treatment. Hydrochloric acid cleaning of copper clad laminate is not only fast, but also very good. In order to be able to better contrast. Two copper clad laminates were used for comparison. Hydrochloric acid is used on the right. On the left, scrub with the purchased rust remover. On the right, the color is used for cleaning, and you can see that the hydrochloric acid cleaning effect is better. Here, the effect of easy rust removal of copperware sold on the Internet was tested. In contrast, hydrochloric acid is better for cleaning.
※Summary※
In this article, we test the effects of the rust remover you just purchased. The effect is really not as noticeable as it appears on the web page. Hydrochloric acid and its effects were compared. In terms of the role of cleaning copper clad laminates, the effect of this purchased oxidant remover is not as good as dilute hydrochloric acid, and in terms of cleaning speed, it is still fast in hydrochloric acid, and in the future, dilute hydrochloric acid is still used to clean copper clad laminates.
