Abstract:
A semiconductor package is disclosed including a first capture pad isolated from an adjacent second capture pad by an insulator; a first plurality of electrically active vias connecting the first capture pad to the second capture pad; a third capture pad isolated from the second capture pad by an insulator; and a second plurality of electrically active vias connecting the second capture pad to the third capture pad. Each via of the first plurality of active vias is non-aligned with each via of the second plurality of active vias. The structure provides reduction of strain on the vias when a shear force is applied to a ball grid array used therewith while minimizing the degradation of the electrical signals.
