Advantages and disadvantages of multilayer circuit boards

The advantages and disadvantages of multi-layer circuit boards 2020-07-23 16:44:00 In this era of rapid development, circuit boards are more and more widely used in our daily lives, and there are objects on them everywhere. We all know that there are many types of circuit boards, so do you know the advantages and disadvantages of multilayer circuit boards? Let's take a look at it together. 1. Advantages: High assembly density, small size and light weight; due to high assembly density, the wiring between components (including components) is reduced, thus improving reliability; the number of wiring layers can be increased, thereby increasing design flexibility It can form a circuit with a certain impedance, and can form a high-speed transmission circuit; it can be equipped with a circuit, magnetic circuit shielding layer, and a metal core heat dissipation layer to meet the needs of multiple functions such as shielding and heat dissipation. It is simple to install and has high reliability. 2. Disadvantages: High cost, long cycle, and high reliability testing methods are required; multilayer printed circuit is the product of the development of electronic technology in the direction of high speed, multi-function, 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 integrated circuits, multilayer printed circuits are rapidly developing in the direction of high density, high precision, and high-level digitalization, and fine lines and small apertures continue to appear Technologies such as penetration, blind hole and buried hole, and high plate thickness to aperture ratio can meet the needs of the market.
