Abstract: The disclosure relates to the field of welding technology. A welding base includes a welding groove defined therein. A limiting member is arranged inside the welding groove for preventing solder and to-be-welded member from loosening from the welding groove after the to-be-welded member is welded to the welding joint. Based on the prior art welding base, the inside of the welding groove of the present disclosure is provided with a limiting member, which can prevent the solder from a longitudinal movement, thus preventing the solder from falling off the welding groove.

Abstract: A microwave component of cavity type includes an integral cavity and a microwave network circuit disposed in the cavity. The cavity has multiple enclosing walls and a chamber defined by said multiple enclosing walls. The chamber is intended for accommodating the microwave network circuit therein. A wiring slot is defined in at least one of the enclosing walls, and at least one first through hole extended through the chamber is provided on each wiring slot. The microwave component of cavity type features small size, simple structure, and wide application. Furthermore, cost may be reduced, batch production may be achieved, use of fasteners such as screws is avoided, and the passive inter-modulation products caused by fasteners are eliminated, as the microwave component is secured without any screws.
