It is made of glass fiber cloth as reinforcing material, impregnated with resin, covered with copper foil, and made by high temperature and hot pressing. It is a product with the largest amount of electronic circuit boards, referred to as FR-4. Due to the rapid development of electronic products, the requirements for copper-clad laminates have increased, and different FR-4 materials have been derived, such as lead-free substrates and high-speed high-frequency boards. This type of sheet has both single and double-sided copper cladding.
