CAKEE Circuit will take you to know about the multi-layer PCB board,

Kayak will take you to know about the multi-layer PCB board, PCB PCB market is developing constantly, which is mainly due to the two aspects of power. First, the market space of PCB application industry is expanding continuously, and the application promotion space of communication industry and 5g industry is very large, which makes the market growth of Multilayer PCB circuit board very fast, and the current application proportion reaches 50-60%. At the same time, the proportion of PCB used in industrial electronic control, medical industry and automobile electronics has also increased significantly, which makes the space of PCB circuit board industry expand continuously. Furthermore, the global PCB industry is transferring to China, which also leads to the rapid development of PCB market space in China.

In PCB PCB design, process not only refers to the category of process data, but also refers to the capacity of the manufacturer. These data are based on the performance of the manufacturer's equipment and the entire design process. In PCB process, three control points are particularly important: etching, drilling and positioning, but other properties also affect the whole process category. With the upgrading of the process, there are also differences in the process categories, so the regulations of the process categories will change accordingly. PCB board is divided into single-sided PCB, double-sided PCB circuit board and Multilayer PCB board. Multilayer PCB circuit board refers to three layers or more layers of circuit board. The manufacturing process of Multilayer PCB circuit board will add the inner layer pressing process on the basis of single and double-sided board. The separation of the slice can also be analyzed. So the multilayer PCB board is usually made of epoxy glass cloth copper foil laminate. The manufacturing process is developed on the basis of the double-sided circuit board with cladding holes.

The process flow of Multilayer PCB circuit board is to etch the inner layer board graphics well. After blackening, semi curing sheet is added according to the predetermined design for lamination, and then a copper foil is placed on the upper and lower surface, and then sent to the press for heating and pressure, and a "double-sided copper clad board" has been prepared for the inner layer graphics. Then, according to the pre-designed positioning system, NC drilling is carried out. After drilling, the hole wall shall be concave and cleaned, and then the following process can be carried out according to the process of double-sided plating and cladding circuit board.
