There are also many types of cable, each of which is different in use.
The gray flat ribbon cable is small in size and light in weight. The original design of the flat ribbon cable board is to replace the larger wire harness. The gray flat ribbon cable is the only way to meet the requirements of miniaturization and movement on the current assembly board of plug-in electronic sub-devices. The gray flat ribbon cable is a copper circuit or printed polymer thick film circuit etched on a polymer substrate. Regarding thin and light devices with compact and complex structures, the design and processing plans range from single-sided conductive lines to complex multilayer three-dimensional assembly. The total weight and volume of the gray cable are reduced by 70% compared to the traditional round wire harness method.
The gray flat ribbon cable can also increase its strength through the use of reinforced materials or liners to obtain additional mechanical stability and other advantages.
