810-000839-005 is a high frequency circuit board for high frequency communication, and its operating frequency is generally above 1GHz. Compared with ordinary circuit boards, high-frequency circuit boards need to have higher impedance matching, signal stability and interference suppression capabilities. Its physical properties, accuracy and technical parameters are very high, and it is often used in automotive anti-collision systems, satellite systems, radio systems and other fields.

The working principle of 810-000839-005 is based on the transmission and loss mechanism of high-frequency electrical signals. High frequency electrical signals are affected by the loss of wire and medium and coupling effect during transmission. Therefore, the design of the high-frequency circuit board needs to consider the impedance matching of the signal transmission line, the loss of signal transmission and electromagnetic radiation and other factors. In addition, the selection of appropriate materials and layout is also the key to ensure the performance of high-frequency circuit boards.

Common high frequency circuit board materials are PTFE, FR-4 and Rogers. The manufacturing process includes the steps of design drawing, production of photolithographic film, etching and finished product inspection. Design drawing is the first use of circuit layout software to draw the circuit schematic and PCB circuit diagram, determine the location of the components and routing planning, and form the final design drawing. Then, a photolithographic film is made to transfer the design pattern to the board surface. Then, the prepared photolithographic film is covered on the circuit board, and the design pattern is etched onto the copper foil surface of the circuit board through the steps of gluing, exposure and etching in the etching machine. Finally, the finished product is tested. The main test items include whether the actual size of the lithographic film conforms to the design drawing, whether the circuit board is vertical, and whether the line is connected.

High-frequency circuit boards and high-frequency transformers have a wide range of applications in wireless communications, radar, satellite technology, medical devices and aerospace. For example, in wireless communication systems, high-frequency circuit boards are used to realize the functions of signal amplification, filtering and demodulation.

In general, the high-frequency circuit board is an indispensable key component in modern electronic equipment, which is crucial to ensure the normal operation and performance of the equipment.
