摘要:
A rigid wave pattern formed on a first side of a substrate in a semiconductor die package. The rigid wave pattern aligns with and overlies the contact fingers formed on the second side of the substrate. When the substrate and dice are encased during the molding process, the rigid wave pattern effectively reduces deformation of and stresses on the dice, therefore substantially alleviating die cracking.

An electronic component is disclosed including a plurality of stacked semiconductor packages. A first such embodiment includes an internal connector for electrically coupling the stacked semiconductor packages. A second such embodiment includes an external connector for electrically coupling the stacked semiconductor packages.
摘要:
An electronic component is disclosed including a plurality of semiconductor packages soldered together in a side-by-side configuration. The packages are batch processed on a substrate panel. The panel includes a plurality of through-holes drilled through the panel and subsequently filled with metal such as copper or gold. These filled through-holes lie along the cut line between adjacent packages so that, upon singulation, the filled through holes are cut and a portion of the filled through-holes are exposed at the side edges of the singulated packages. These exposed portions of the filled through-holes form vertical surface mount technology (SMT) pads. After the semiconductor packages are singulated and the SMT pads are defined in the side edges, SMT is used to solder the SMT pads of a first semiconductor package to the respective SMT pads of a second semiconductor package to structurally and electrically couple the two packages together side-by-side.
摘要:
A strengthened semiconductor die substrate and package are disclosed. The substrate may include contact fingers formed with nonlinear edges. Providing a nonlinear contour to the contact finger edges reduces the mechanical stress exerted on the semiconductor die which would otherwise occur with straight edges to the contact fingers. The substrate may additionally or alternatively include plating traces extending at an angle from the contact fingers. Extending at an angle, at least the ends of the plating traces at the edge of the substrate are covered beneath a lid in which the semiconductor package is encased. Thus, when in use with a host device, contact between the ends of the plating traces beneath the lid and contact pins of the host device is avoided.

A semiconductor package having a low profile is disclosed. In embodiments, a surface mounted component may be mounted directly to the core of the semiconductor package substrate, so that there is no conductive layer, plating layers or solder paste between the component and the substrate core. The surface mounted component may be any type of component which may be surface mounted on a substrate according to an SMT process, including for example passive components and various packaged semiconductors.

摘要:
A method of forming a semiconductor package with smooth edges, and a semiconductor package formed thereby is disclosed. In embodiments, after encapsulation, the semiconductor packages may be at least partially singulated from the panel by making one or more cuts through the panel to define one or more edges of the semiconductor package. The one or more edges may be smoothed by applying a laminate to the edges. The edges receiving the laminate may include any edge between a top and bottom surface of the package.

A method of forming a semiconductor card. A semiconductor package having a damaged controller die is reclaimed. The reclaim process includes severing the electrical connections between the controller die and the semiconductor package substrate without exposing the passive component. In one embodiment, the cutting tool comprises a saw blade. An electrically insulating material is deposited over the exposed bond wires to complete the reclaim process. The reclaimed package and a new controller die are affixed to a second substrate to electrically couple the memory die of the reclaimed package with the new controller die—forming a new package. The new package is encapsulated to form a new memory card.
