Abstract
A flexible circuit board with specific shielding planes is used for low voltage differential transmission mode circuits. Both the impedance and the transmission time for the transmission line in the circuit board are controlled by shielding planes with varied void opening patterns. Capacitance and slow wave effects related to the combination of void opening patterns and the location configuration related to locations of void opening patterns are used to improve the impedance and transmission timing for the transmission line in the circuit board.
