Abstract
A high density flexible circuit for coupling electrical devices. The flexible circuit has signal and ground traces on both sides of the flexible circuit. Each signal trace is surrounded by ground traces. There is a ground trace on either side of each signal trace and two ground traces located below each signal trace. This system of placing ground traces surrounding each signal trace reduces electrical noise between the signal traces and reduces the electrical capacitance of the circuit.
