A manufacturing process for embedding long copper blocks in 8-layer printed circuit board(PCB)is introduced.The manufacturing process of embedded multi-layer PCBs is more difficult than that of conventional multi-layer PCBs,and the production difficulties of embedded copper blocks are usually as follows:after the process optimization of slotting,copper block production,pressing and stacking,the position of the copper block is not shifted in the vertical and horizontal directions,the product surface is flat,the customers'product index requirements are met,and the yield of the embedded copper block PCB can be significantly improved.The manufacturing process of PCB with embedded copper blocks described in this article can solve the production technical problems of products with special requirements for the location of embedded copper blocks.
