The present invention is applicable to the technical field of radio frequency connection, and provides a method for welding radio frequency strip lines of a printed circuit board with radio frequency cables. The method includes: opening a groove on the printed circuit board for accommodating radio frequency cables; Open the Via hole, plate the metal on the side wall of the Via hole and the groove, and connect the Via hole to the RF strip line ground, and connect the side wall of the groove to the inner and outer layers of the printed circuit board; peel off the RF cable to expose the first A core wire of a preset length and a metal sheath of a second preset length; the stripped RF cable is placed in the groove, the core wire is lapped on the RF strip line of the printed circuit board, and the metal sheath is welded to the groove , and weld the core wire with the RF strip line, so that the RF cable and the printed circuit board are in a horizontal state, realizing the horizontal transition from the coaxial transmission of the cable to the RF strip line of the printed circuit board, and improving the transmission characteristics.
Description
technical field [0001] The invention belongs to the technical field of radio frequency connection, in particular to a method for welding radio frequency strip lines of printed circuit boards with radio frequency cables. Background technique [0002] At present, two or more independent circuit units inside a microwave component usually require radio frequency transmission, and above 10 GHz are mostly hard-connected by radio frequency connectors or connected by cable components, which takes up a lot of space and costs high. At present, RF cables can also be used to directly weld the RF strip line of the printed circuit board. The RF cable and the printed circuit board form a certain angle, and the parasitic effect of the solder joint is relatively large, which cannot meet the RF frequency transmission characteristics. Contents of the invention [0003] In view of this, the embodiment of the present invention provides a method for welding the RF stripline of a printed circuit...
