The basic requirements for the processing of high-frequency microwave board
1, the substrate,engineer has been based on the actual needs of the impedance, choose a specific permittivity, dielectric thickness, copper foil thickness,therefore, when accepting the order, to be carefully checked, must meet the design requirements.
2, The requirements of transmission lines making precision ,the high frequency signal transmission is very strict for the characteristic printed circuit board, that the production of precision requirements for the transmission line is ± 0.02mm , the edge of transmission line to be very neat, tiny burrs, nicks are not allowed to produce.
3, the characteristic impedance of the transmission line of high-frequency microwave board directly affects the transmission quality of the microwave signal. The size and thickness of the characteristic impedance of the copper foil has a certain relationship, especially for microwave board hole metallization, coating thickness only affects the total thickness of the copper foil, and affect the accuracy of engraved lead after pitting room, so the size of the coating thickness and uniformity, to be strictly controlled.
Application:
Our FR4 PCBs could be kindly used in many fields includes communication, computers, medical equipment, home automation product, CCTV product, consumer electronics, automobile industry,etc. Through many years experience in this line, we have gained a good reputation and considered as reliable and long-term cooperation manufacturer at home and abroad.
