There are two main methods for installation of SMA RF connectors: (1) welding the center conductor and screwing the shield. (2) Crimp the center conductor, crimp the shield. Other methods are derived from the above two methods, such as welding the center conductor and crimping the shield.
SMA RF connector method (1) is used in situations where there are no special installation tools; Due to the high efficiency of crimp loading method, reliable termination performance, and the design of special crimping tools to ensure that each cable fitting part is the same, so with the development of low-cost loading tools, welding center conductor crimp shield will be increasingly popular.
