At present, there are many kinds of epoxy boards on the market, which are roughly divided into yellow and green. Does the color of epoxy boards affect performance and quality? What is the difference between green epoxy board and yellow epoxy board?

The full name of epoxy board is epoxy resin laminate, which is made of electronic grade glass fiber cloth impregnated with epoxy resin.Electronic grade fiberglass cloth is an important basic material in this field, and its main function is reinforcement. Epoxy resin is an important thermosetting plastic, which can be used as adhesive, coating, curing agent, and it is used as a matrix.

Green epoxy board, the models are roughly divided into FR4, G10, G11, EPGC, etc., they also have yellow, the color of the same model does not affect its quality, there is no distinction, their performance is better than 3240 epoxy board, and 3240 has only one color of yellow. Green is more expensive than yellow. Take fr4 as an example. The maximum operating temperature is 150°C. Even if it exceeds a little, there will be no problem as long as it is in a short time. It has high strength, certain chemical resistance, and resistance to Friction, light weight, fatigue resistance, and most importantly, flame retardant.

The yellow epoxy board is generally the 3240 model, and its performance will be slightly worse than the green one, but how to choose a suitable board should also be combined with the needs of the purchase itself. If the electrical performance requirements are not too high, the yellow epoxy board can also be used. Its price is much cheaper and the cost performance is very high. Therefore, whether the green epoxy board or the yellow epoxy board is better should be combined with the purchase demand to choose the most cost-effective product.
