Abstract
Abstract Elongated, flexible printed circuit board coaxial cable which is made using a pattern on a flexible PCB substrate on which coaxial cables are formed is described. A series of slits and folds allows one or more elongated cables to be formed in each pattern. Such cables are particularly useful for connecting multi-connector apparatus of the type which requires coaxial cables interconnected in very close spaces, such as the type used in ultrasound transducers. The method for manufacturing such elongated, flexible printed circuit board coaxial cable is also described. The method includes forming a pattern on a flexible PCB substrate on which coaxial cables are formed. Thereafter, a series of slits and folds allows one or more elongated cables to be formed in each pattern. Such cables are particularly useful for connecting multi-connector apparatus of the type which requires coaxial cables interconnected in very close spaces, such as the type used in ultrasound transducers.
