Perfect Making of the Multilayer PCB with the Perfect Setting
The requirements for reducing the weight and volume of radio equipment necessitate an increase in the density of installation, which leads to the need to improve both the design and the technology of connecting parts and functional units.

The possibility of placing integrated circuits on a multilayer printed circuit board can be judged on the basis of the following example: hundreds of monolithic integrated circuits in flat cases are installed on a circuit board with an area of up to 900 cm2 and a volume of several tens of cubic centimeters. In the Pcb factory you can expct such perfection of the making.
The First Step
Multilayer pcb boards are designed to accommodate predominantly multi-pin circuits on them in the case where it is not possible to place conductors on two-sided boards. The number of MG1P layers is determined when the electrical circuit is divided into functional circuits, and it is desirable that each functional circuit is located on a separate layer
The total thickness of the MPP is selected taking into account the mechanical strength requirements for the design of a multilayer printing unit, and is provided with the necessary selection of thicknesses of foil and insulating materials.
Due to the low mechanical strength, warpage and the difficulty of manufacturing large MPPs, it is recommended that they be designed as small-sized. The dimensions of multilayer printed circuit boards should not exceed 150 X 180 mm. The recommended number of layers is 3-4.
A multilayer rigid-flex pcb board consists of several layers of individual printed circuit boards assembled in a package and interconnected. The use of multilayer boards is an effective method of obtaining interconnects for equipment with a high packing density of components. A multilayer printed circuit board is the carrier of a printed circuit board and a large number of components on this board.
A multilayer board can significantly reduce the space required to provide interconnects. Thus, the reliability of the boards and interconnects should significantly exceed the reliability of the integrated circuits themselves. You can visit https://www.szrcypcb.com/
