What is Cavity PCB | High Speed PCB?
Cavity PCB is a specially designed printed circuit board characterized by the formation of cavities or chambers inside the board. These cavities can be used to embed components required for high-speed signal transmission, such as microwave antennas, filters, etc. By placing these components inside the board, Cavity PCB can achieve shorter signal transmission paths, thereby increasing signal transmission speed and stability.
In traditional planar circuit board designs, high-speed signal transmission usually requires long paths, which may lead to signal attenuation, increased delay, and electromagnetic interference. Cavity PCB effectively shortens the signal transmission path by forming a cavity inside the board and embedding the components required for high-speed signal transmission. This design can not only reduce the signal transmission delay, but also reduce the attenuation of the signal during the transmission process, thereby improving the signal transmission speed and stability.
In addition, the cavity structure of Cavity PCB can also act as electromagnetic shielding to reduce the impact of external electromagnetic interference on the circuit. By setting up an appropriate shielding structure inside the cavity, external interference signals can be effectively isolated and the stable operation of the circuit can be ensured. This is particularly important for some application scenarios that are very sensitive to signal interference, such as communication equipment, radar systems, etc.
In addition, the cavity design of Cavity PCB can also improve the heat dissipation performance of the circuit board. Placing a heat dissipation structure or thermal conductive material inside the cavity can effectively improve the heat dissipation efficiency of the circuit board and reduce the operating temperature of the components, thereby extending its service life and improving stability.
Overall, Cavity PCB provides a new solution for high-speed signal transmission by forming a cavity inside the board. Its unique design concept and advantages make it an indispensable part of future electronic equipment, bringing new possibilities to the development of the electronics industry.
