In the case of a large number of data interconnection and cross development needs, PCB circuit boards want students to achieve such a very satisfactory performance, it is necessary to expand the board layer to two layers to carry out more than one, so the emergence of multilayer PCB circuit boards, multilayer PCB circuit boards, the original purpose of multilayer pcb fabrication is to provide the study of the routing technology path research to learn more degrees of freedom.
Multilayer PCB is made of two or more conductive layers (copper layer) stacked on top of each other. The copper layers are bonded together by a resin layer (semi-cured board) and are one of the most complex types of printed circuit boards. What are the basic components of a multi-layer printed circuit board?
1. Signal Layer
Multilayer PCB to achieve information interaction is most important to have three signal layers. By soldering the components and signal lines placed in the multilayer PCB, so that the multilayer PCB can realize the normal function of information services. Through the use of the information layer, multi-layer PCB circuit boards show good information interaction capabilities, and through the use of the multi-layer PCB circuit boards can achieve better electronic control capabilities.
2, the internal power layer
The signal layer and the internal power layer are connected to each other through the apertures in the multilayer PCB for better electronic performance, PCB factoryand the internal power layer is a unique accessory to use this internal power layer for better connectivity.
3. Mechanical Layer
An accessory with information on plate making and preparation method instructions allows the use of multilayer boards to draw the framework of the board and place a better process to achieve a concise planning of the page. This mechanical layer also makes the connection of technologies more clear and vivid.
It is made up of two layers of copper foil sandwiched between two layers of epoxy resin and glass fiber, also known as FR-4. While various dielectric materials are available, FR-4 is the most often used core material in PCB construction.
