A concave cavity PCB is a high-performance circuit board designed with a concave structure. By forming a concave space within the circuit board, space can be utilized more efficiently to promote miniaturization and integration of electronic devices. It makes full use of the internal space of multilayer circuit boards in the manufacturing process and can place components such as resistors, microcontrollers, heat sinks, etc. in the concave cavities to achieve high-density integration.
There are significant differences between the design and application of a cavity PCB and a normal circuit board.
A concave circuit board is a circuit board designed with a concave structure, which allows the board to achieve a higher level of integration and a smaller size. In contrast, normal circuit boards are usually more conventional in design, less integrated, and larger. Second, it is usually used in highly integrated, high-performance electronic devices, such as mobile communications, satellite communications, avionics, and other fields. In contrast, ordinary circuit boards are widely used in a variety of electronic devices, but their integration and performance is relatively low. In addition, the manufacturing process is different from that of ordinary circuit boards. The manufacturing of concave circuit boards requires the use of special processes and technologies, such as the use of internal space in multilayer circuit boards, precision component placement, and soldering. In contrast, the manufacturing process for ordinary circuit boards is relatively simple and usually utilizes a single or dual-panel design.
