摘要:
Electronic devices include a substrate with first and second pairs of conductive traces extending in or on the substrate. A first conductive interconnecting member extends through a hole in the substrate and communicates electrically with a first trace of each of the first and second pairs, while a second conductive interconnecting member extends through the hole and communicates electrically with the second trace of each of the first and second pairs. The first and second interconnecting members are separated from one another by a distance substantially equal to a distance separating the conductive traces in each pair. Electronic device assemblies include a transmitting device configured to transmit a differential signal through a conductive structure to a receiving device. The conductive structure includes first and second pair of conductive traces with first and second interconnecting members providing electrical communication therebetween.

Microelectronic packages with leadframes, including leadframes configured for stacked die packages, and associated systems and methods are disclosed. A system in accordance with one embodiment includes a support member having first package bond sites electrically coupled to leadframe bond sites. A microelectronic die can be carried by the support member and electrically coupled to the first packaged bond sites. A leadframe can be attached to the leadframe bond sites so as to extend adjacent to the microelectronic die, with the die positioned between the leadframe and the support member. The leadframe can include second package bond sites facing away from the first package bond sites. An encapsulant can at least partially surround the leadframe and the microelectronic die, with the first and second package bond sites accessible from outside the encapsulant.

摘要:
A rerouting element for a semiconductor device that includes a dielectric film that carries conductive vias, conductive elements, and contact pads. The conductive vias are positioned at locations that correspond to the locations of bond pads of a semiconductor device with which the rerouting element is to be used. The conductive elements, which communicate with corresponding conductive vias, reroute the bond pad locations to corresponding contact pad locations adjacent to one peripheral edge or two adjacent peripheral edges of the rerouted semiconductor device. The rerouting element is particularly useful for rerouting centrally located bond pads of a semiconductor device, as well as for rerouting the peripheral locations of bond pads of a semiconductor device to one or two adjacent peripheral edges thereof. Methods for designing and using the rerouting element are also disclosed, as are semiconductor device assemblies including one or more rerouting elements.
