Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a high-frequency circuit board which is convenient to dismantle. Background Art

[0002] High-frequency circuit boards are special circuit boards with higher electromagnetic frequencies. Generally speaking, high frequency can be defined as a frequency above 1 GHz. It has very high requirements for various physical properties, precision, and technical parameters. It is often used in automotive anti-collision systems, satellite systems, radio systems and other fields. High-frequency circuit boards include a core board with a hollow groove and a copper-clad board bonded to the upper and lower surfaces of the core board by glue flow. During use, the components on the circuit board need to be protected as much as possible to prevent them from being damaged.

[0003] Existing high-frequency circuit boards that are easy to remove generally use a clamping method to clamp the circuit board. However, this clamping method may cause the circuit board to deform because the pressure on the circuit board is not evenly distributed, affecting the internal signal transmission, and may even cause damage to the circuit board in severe cases. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a high-frequency circuit board that is easy to dismantle, so as to solve the technical problem that the circuit board is deformed due to uneven pressure, affecting the internal signal transmission.

[0012] Furthermore, four second right-angle frames are provided, and second sliding plates are provided between adjacent second right-angle frames, and two ends of the second sliding plates are slidably connected to adjacent second right-angle frames.
