A 5g communication pcb board

Abstract

The invention discloses a PCB board for 5G communication, comprising a top layer and a bottom layer, the upper end surface of the top layer includes an electrical boundary layer and a component layer, the electrical boundary layer is a square layer, and four Mounting holes, the four mounting holes are symmetrically distributed on the four corners of the electrical boundary layer, the component layer is located in the middle of the electrical boundary layer; the lower end surface of the top layer is provided with a top layer of solder resist, and the top layer of resistance The lower end surface of the solder layer is connected with the first cured plate layer; the upper end surface of the bottom layer is provided with a bottom solder resist layer, and the upper end face of the bottom layer solder resist layer is connected with a second cured plate layer, and the first cured plate layer and An intermediate layer is arranged between the second cured board layers, and a first protective layer and a second protective layer are arranged in the intermediate layer to protect the intermediate layer. A power supply layer is arranged in the intermediate layer, and the two sides of the power supply layer The terminal is provided with a sub butt joint and a female butt joint, which can connect different PCB boards to each other.

Description

technical field [0001] The invention belongs to the technical field of circuit boards, in particular to a PCB board for 5G communication. Background technique [0002] PCB, the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made by electronic printing, it is called "printed" circuit board; 5G network is the fifth generation mobile communication network, and its peak theoretical transmission speed can reach 1GB every 8 seconds, which is several times faster than the transmission speed of 4G network. hundred times. For example, a 1G movie can be downloaded within 8 seconds; with the birth of 5G technology, the era of sharing 3D movies, games and ultra-high-definition (UHD) programs with smart terminals is coming to us. The application of 5g will become more and more widespread. [0003] The p...

Problems solved by technology

[0003] The publication number is CN210157464U, a PCB circuit board applied to 5g communication, including PCB main body, installation frame, protective frame, studs, springs and fastening mechanism, the surface of PCB main body is provided with installation frame, and the surface of PCB main body is located in the installation frame Chip solder joints are reserved inside, the protective frame is connected to the installation frame, the studs pass through the four corners of the protective frame and respectively connected to the four corners of the installation frame, and the outer side of the studs is located above the protective frame. The upper surface of the frame is also provided with several fastening mechanisms, and the bottom of the fastening mechanism is located inside the protective frame; the structure of the protection device of the invention is complex, and the protection effect on the inner layer of the PCB is relatively poor, and at the same time, during the use of the PCB It is easy to cause internal circuits to interfere with signal transmission. When doing some designs, multiple PCB boards need to be used at the same time, and it is further necessary to connect different PCB boards externally through additional components. The operation is complicated and the PCB board needs to be occupied. The working space of the board, in order to solve the above problems, a solution is now provided
