Flat Cables for Lightweight Interconnections

摘要

The data obtained for the tests conducted indicates that flat conductor cables can be manufactured to meet application requirements of Army ground support equipments, missile and space vehicles. However, additional studies are required to determine the behaviour and reliability of flat cables at various temperature extremes and space environments. Although the data indicates that flat cable can be manufactured to meet specific requirements, considerable differences were obtained between similar constructed cables, fabricated with the same insulants but by different manufacturers. In general, each manufacturer seemed adept in the manufacture of a specific cable design. The majority of cables failed to meet the elongation requirements of 1% and the teflon insulated cables failed to meet the 5000 psi tensile strength requirements, however, the remaining cables meet the requirements of NAS/IPC specification for the test conducted. Slight discolorations and warping as a result of various conditions were observed for many of the specimens. (Author)
