       Electronic products with double-sided and multilayer printed circuit boards are now generally fr-4 base material, which is a copper foil flame retardant epoxy glass cloth board.CEM-3 is a new type of substrate material developed on the basis of fr-4.In recent years, Japan has used CEM-3 to replace fr-4, even more than fr-4, and about 55% of both panels are CEM-3.A, CEM - 3 is a kind of compound FR - 4 is made up of copper foil and copper foil board by of flame retardant epoxy resin impregnated glass fiber cloth laminate, and CEM - 3 unlike FR - 4 adopted the composite glass cloth and glass mat base material, also known as composite base material, rather than to simply glass cloth.The production process of CEM-3 is similar to that of fr-4, and the glue on the glass felt can be made of vertical glue or horizontal glue. The epoxy resin system used is the same as that of fr-4.To improve performance, a certain amount of filler is usually required.The suppression pressure is generally half as low as the fr-4.In order to meet the different thickness requirements, the glass felt of different scales can be used, and 50g, 75g and 105g are commonly used.
