Abstract: One or more electronic devices that are mounted on a substrate, including at least one cooling plate in contact with the one or more electronic devices, are encapsulated. The substrate is clamped between a first mold half and a second mold half which define a molding cavity for molding the one or more electronic devices. A cavity insert movably located in the first mold half is projected into the cavity in order to contact and apply a sealing pressure onto the at least one cooling plate. After introducing a molding compound into the cavity at a first fill pressure, the molding compound in the cavity is packed by applying a second fill pressure which is higher than the first fill pressure. During this time, the sealing pressure is maintained at values that are higher than the first fill pressure and the second fill pressure.

Abstract: An tri-axis accelerometer is disclosed. The tri-axis accelerometer includes a mass, a first group of capacitance, a third group of capacitance being neighbor to the first group of capacitance. The mass defines an upper surface, a lower surface parallel to the upper surface and a side wall connecting the upper surface and the lower surface. The first group of capacitance includes a first movable electrode and the third group of capacitance includes a third movable electrode. The first movable electrode is perpendicular to the third movable electrode.

Abstract: A accelerometer includes a base, a pair of fixed sensing blocks anchored to the base, a plurality of elastic linkages connected to the base, and a movable sensing block sandwiched between the pair of fixed sensing blocks and suspended in the base by the elastic linkages for moving either along a first or a second axes or shifting along a third axes. Each fixed sensing block defines four fixed sensing sections and each fixed sensing section sets in space with respect to the other fixed sensing sections. A projection of each fixed sensing section along a third axes exceeds the movable sensing block in a direction of the first and second axis, respectively.
