ABSTRACT:
The signal transmission flat cable provided includes a first layer of substrate membrane, a second layer of a plurality of parallel traces for transmitting the signal, a third layer of finger array and a fourth layer of thin polyester membrane. The third layer of finger array covers the second layer. The fourth layer of thin polyester membrane is used to protect the second layer and third layer. The signal transmission flat cable is characterized in that the plurality of finger arrays are provided in the third layer at a plurality of predetermined locations along the flat cable and each of the plurality of finger arrays is spaced from each other by a given distance. A glue material is provided to bond the fourth layer and the second layer along the given distance. As a result, the flat cable has the module capability by which an user may cut away the excess portion of the flat cable depending on different requirement, such that the remaining portion of the flat cable may be inserted into the keyboard socket on the motherboard of a computer.
