Top 10 PCB prepreg manufacturers in the world in 2023

Do you know about PCB prereg? Prepreg, also known as “PP sheets”, is a dielectric material and bonding material in the production of multilayer PCB, composing of glass fiber, reinforcement materials and epoxy resin. The prepreg (adhesive sheet) used in the production of multi-layer printed boards is mostly made of glass fiber cloth as a reinforcement material.

The dielectric constant is about 4.0~4.5. At room temperature, the prepreg is solid, and when heated at high temperature, the prepreg gels the upper and lower copper foils together, and the prepreg becomes the medium in the middle.

As the experts of PCB industry, you have a good knowledge about PCB prereg. However, a good PCB prepreg manufacturer can make production more smoothly. So this article will list top 10 PCB prepreg manufacturers in the world in 2023.
