It's TECHNOLOGY THURSDAY! Perhaps you have asked yourself: Why are printed circuit boards green? The most commonly used base material for printed circuit boards is FR4 and is made from an epoxy resin and glass fiber. Epoxy resin is a light, almost transparent matt yellow color which deepens with increasing thickness. The printed circuit board, on the other hand, is a rich green color. Find out why that is in the blog below!
