A Novel Structure to Suppress the Crosstalk Noise on Coupled Plating Bars

In the BGA family package, plating bars must be added in the manufactured processing , However they will cause discontinuities[1]¡Bradiation effect[2] and bad transmission efficiency[3]~[6].This paper considers the signal transmission problem caused by the couple plating lines. This thesis starts from analyzing the different terminations of the couple lines, then proposes a novel L-stub element structure which can decrease the crosstalk noise efficiently on the plating lines. Discussion of the L-stub length ratio, L-stub position and the numbers of the L-stub then provides the useful range. The basic idea is to use the reflection of source to cancel the original couple and doesn¡¦t have to add additional element. In addition, it compares well with other methods which are also designed for reducing crosstalk and circuits are implemented to prove our design. Last of all, using the eye diagram to manifest the signal quality improvement.
