Cable Assembly Attachment Methods
RF coaxial cable assemblies consist of a coaxial cable and one or more RF coaxial connectors terminating one or both ends. There are a wide range of both coaxial cable and coaxial connectors. Amongst the variation in coaxial connectors is the method in which the coaxial cable is attached to the coaxial connector. There are three main attachment methods: crimp method, compression method, and solder method. Compression method is not as common as the crimp or solder method for RF applications outside of TV/broadcast and other niche high volume applications. Hence, this method will only be mentioned here.Crimp Method
Generally, properly crimped connections are moisture and debris barriers and provide a rugged mechanical connection resilient to shock and vibration. However, under repeated flexure or over-bending, center conductor strands could become loose within the center contact crimp section, which may lead to degradation or failure of the connection.Solder Method
The main drawback to the solder method is that it requires a skilled assembly operator and generally longer assembly times than with crimped connections. The solder method is compatible with flexible, semi-rigid/semi-flex, and rigid coaxial connectors.
