Epoxy board is a laminated board, which is mainly made of epoxy resin binder and paper, cotton and other substrates. There are many types of epoxy boards, including 3240 epoxy boards, G11 epoxy boards, G10 epoxy boards and FR-4 epoxy boards, etc. They have similar properties but differ in detail. Now epoxy plate can be said to be an indispensable component in electronic products, it can be used as the splint mold and insulation components of electronic products, etc. Some special epoxy plate can also be processed into light and thin cell phone holsters. Because it is such an important part, there are inevitably some defective products in the market, so how do epoxy board manufacturers look at the quality of epoxy boards?

The first thing to look at is the appearance of the epoxy. The epoxy sheet should be smooth. Any dents, scratches or other marks are defective. Also, the sides of the crosscut should be neat, some rough edges have burrs and are sticking. Epoxy panels are colored, including aqua, yellow, black and white, etc. The epoxy should look uniform and full in color. The epoxy has strong strength and good toughness, you can try to bend it or force it when you test its performance. If it's weak and easy to fold, its quality is not good. Epoxy is waterproof and resistant to chemical corrosion, and can work well in wet environment. So this can also be used to test its performance. As an insulating material, insulation performance must be good, non-conductive, even in harsh environments.

The quality of the epoxy board is basically to see the above points. If the appearance is beautiful, and physical and chemical properties are good, the quality will be good. A lot of poor quality epoxy boards can be seen from their appearance. In the mixed market, we also need to learn relevant knowledge if we want some product, so as not to be deceived by others.
