A stackable via package includes a substrate having an upper surface and a trace on the upper surface, the trace including a terminal. A solder ball is on the terminal. The solder ball has a solder ball diameter A and a solder ball height D. A via aperture is formed in a package body enclosing the solder ball to expose the solder ball. The via aperture includes a via bottom having a via bottom diameter B and a via bottom height C from the upper surface of the substrate, where A<B and 0=<C<1/2×D. The shape of the via aperture prevents solder deformation of the solder column formed from the solder ball as well as prevents solder bridging between adjacent solder columns.

A stackable variable height via package includes a substrate having a first surface and terminals thereon. The terminals include a first terminal and a second terminal. Vias are on the terminals, the vias including a first via on the first terminal and a second via on the second terminal. The first via has a height from the first surface of the substrate less than a height of the second via from the first surface of the substrate. The package further includes a package body and via apertures in the package body to expose the vias. Forming the stackable variable height via package with variable height vias readily accommodate stacking of additional packages having different types of terminals, e.g., LGA and BGA type packages, as well as variable degrees of warpage on the stackable variable height via package. Further, the vias are formed with a minimum pitch.

Methods and systems for a molded cavity substrate Micro Electro Mechanical Systems (MEMS) package may comprise a MEMS electronic component, a base substrate comprising a first conductive through via, a molded ring coupled to the base substrate, and a lid substrate comprising dielectric material and a metal layer. The molded ring comprises a second conductive through via and a molded cavity, and the MEMS electronic component is located within the molded cavity. The base substrate may comprise a laminate substrate. The lid substrate may comprise a cavity port. A base assembly mounting adhesive may couple an inner surface of the lid to a principal surface of the molded ring. The dielectric material may comprise mold material. The molded ring may comprise mold compound adherent to an outer region of an inner surface of the base substrate with a central region of the base substrate exposed by the molded ring.

Molded cavity substrate MEMS package fabrication method and structure

A molded ring includes a molded cavity of a molded cavity substrate MEMS package. The molded ring is formed by molding a dielectric material directly upon a substrate. As molding is a relatively simple and low cost process, the molded ring and thus molded cavity are formed at a minimal cost. This, in turn, minimizes the cost of the molded cavity substrate MEMS package.

An electronic component assembly and a method for making an electronic component assembly. A non-limiting example electronic component assembly may, for example, comprise a lower component comprising a plurality of upward extending pins, and an upper component comprising a plurality of respective terminals, each which comprising a respective reflowable conductive structure that extends downward to a respective one of the plurality of upward extending pins.

A method of forming a stackable protruding via package including enclosing an electronic component and electrically conductive first traces on a first surface of a substrate in a package body. Protruding via apertures are formed through the package body to expose the first traces. The protruding via apertures are filled with solder to form electrically conductive vias in direct physical and electrical contact with the first traces. Via extension bumps are attached to first surfaces of the vias. The vias and the via extension bumps are reflowed to form protruding vias. The protruding vias extend from the first traces through the package body and protrude above a principal surface of the package body. The protruding vias enable electrical connection of the stackable protruding via package to a larger substrate such as a printed circuit motherboard. Further, the protruding vias in accordance with one embodiment are formed with a minimum pitch.
