A MEMS inertial sensor is secured within a premolded-type package formed, at least in part, from a low moisture permeable molding material. Consequently, such a motion detector should be capable of being produced more economically than those using ceramic packages. To those ends, the package has at least one wall (having a low moisture permeability) extending from a leadframe to form a cavity, and an isolator (with a top surface) within the cavity. The MEMS inertial sensor has a movable structure suspended above a substrate having a bottom surface. The substrate bottom surface is secured to the isolator top surface at a contact area. In illustrative embodiments, the contact area is less than the surface area of the bottom surface of the substrate. Accordingly, the isolator forms a space between at least a portion of the bottom substrate surface and the package. This space thus is free of the isolator. Moreover, due to the low moisture permeability of the package, further production steps can be avoided while ensuring that moisture does not adversely affect the MEMS inertial sensor within the cavity.

Packaged microchip with premolded-type package

An electrical interconnect apparatus has a mounting member with a plurality of sides. The mounting member is formed from an insulator as a cuboid. Moreover, the mounting member also may be formed from a flexible circuit. Among other things, the plurality of sides includes an interface side. At least two of the plurality of sides are in electrical communication with the interface side.

Multi-surface mounting member and electronic device

An optical mirror module has an interface port that is spaced from a corresponding die. More specifically, the optical mirror module includes a substrate and a die having at least one mirror and circuitry to control the at least one mirror. The optical mirror module defines a plane that is substantially parallel to the die. The optical mirror module further includes the noted interface port, which is adapted to electrically couple the circuitry with a device external to the optical mirror module. As suggested above, the interface port is located on the substrate and spaced from the die on the plane.

Optical mirror module

A packaged microchip has a stress sensitive microchip having a microchip coefficient of thermal expansion, a package having a package coefficient of thermal expansion, and an isolator having an isolator coefficient of thermal expansion. The isolator is connected between the stress sensitive microchip and the package. The microchip coefficient of thermal expansion illustratively is closer to the isolator coefficient of thermal expansion than it is to the package coefficient of thermal expansion.
