on the inner layers would occupy the space between the components. The increase in the need for multilayer printed circuit boards with more than two, four and especially more than six layers of copper has imprimat metalizate circuit gauri cu been concurrent with the adoption of surface mount technology. "Through holes" components are
as medicine and aeronautics to benefit from smaller and lighter equipment that has allowed them a high degree of development and effectiveness. Today, in our house, almost every electronic device that helps us in the household contains a larger or imprimat gauri metalizate circuit cu smaller printed circuit: refrigerator, vacuum cleaner, television, but
the multi-layer PCBs, the most common are the four-layer ones. The four-layer board has many more routing options in the internal layers compared to the imprimat metalizate gauri cu circuit two-layer board, and often part of the internal layers are used as a ground plane or power plane, to achieve better signal integrity, higher signaling frequencies, and better power supply
