Advantages: High assembly density, small size, and light weight. Due to the high assembly density, the connection between various components (including components) is reduced, thus improving reliability; Can increase the number of wiring layers, thereby increasing design flexibility; Can form a circuit with a certain impedance; Can form high-speed transmission circuits; Circuit and magnetic shielding layers can be set, and metal core heat dissipation layers can also be set to meet special functional needs such as shielding and heat dissipation; Easy installation and high reliability. Disadvantages: High cost; Long cycle; High reliability testing methods are required. Multilayer printed circuits are the product of the development of electronic technology towards high speed, multifunctional, large capacity, and small volume. With the continuous development of electronic technology, especially the extensive and in-depth application of large-scale and Very Large Scale Integration, multi-layer printed circuits are rapidly developing towards high-density, high-precision, high-level digital direction, and technologies such as fine lines, small aperture penetration, blind hole burial, and high plate thickness to diameter ratio have emerged to meet the needs of the market.
