CCable assembly services manufacture custom, connectorized coaxial, fiber optic, and multi-conductor cables for specific applications on a contractual basis. They are located across the United States and around the world and vary in terms of capabilities. Suppliers that provide design assistance can help with cable and connector selection, layout and manufacturing techniques, and computer aided design (CAD). They may also be able to help upgrade or redesign, re-evaluate or modernize existing cable assemblies to improve performance and/or reduce manufacturing costs. Some cable assembly services provide rapid prototyping or short-run manufacturing prior to mass production. Others handle all aspects of the manufacturing process, including soldering, termination, wrapping and testing. Suppliers with just-in-time manufacturing capabilities can produce parts on demand. Cable assembly services with formal quality assurance or testing processes ensure the quality of all manufactured products and, in some cases, provide test results.
