A non-magnetic hermetic package includes walls that surround an open cavity, with a generally planar non-magnetic and metallic seal ring disposed in a continuous loop around upper edges of the walls; a sensitive component that is bonded within the cavity; and a non-magnetic lid that is sealed to the seal ring to close the cavity by a metallic seal.

A semiconductor package may include; a first substrate, a first semiconductor chip disposed on the first substrate, an interposer disposed on the first semiconductor chip, a connecter spaced apart from the first semiconductor chip in a first horizontal direction and extending between the first substrate and the interposer, wherein the connecter directly electrically connects the first substrate and the interposer, a capacitor disposed between the connecter and the first semiconductor chip, and a guide pattern including a first guide portion and an opposing second guide portion spaced apart in the first horizontal direction, wherein the first guide portion is disposed between the connecter and the capacitor, the second guide portion is disposed between the capacitor and the first semiconductor chip, and at least part of the capacitor is inserted between the first guide portion and the second guide portion.

A package includes a package component, a device die over and bonded to the package component, a metal cap having a top portion over the device die, and a thermal interface material between and contacting the device die and the metal cap. The thermal interface material includes a first portion directly over an inner portion of the device die, and a second portion extending directly over a corner region of the device die. The first portion has a first thickness. The second portion has a second thickness greater than the first thickness.

A method for mounting an electrical component to a substrate may include mounting the component onto the substrate, forming a cover including a thermally softenable or hardenable material and a contacting structure defined by integrated conductor paths, mounting the cover onto a mounting side of the substrate and onto the component mounted on the substrate, such that (a) the cover laterally traverses the component, (b) first contact surfaces of the contacting structure engage with the substrate at a first joining level defined at the mounting side of the substrate, and (c) second contact surfaces of the contacting structure engage with the component at a second joining level at the top side of the component, the second joining level being different than the first joining level. After assembling the components, joining connections at the first and second joining levels may be completed by a temperature or pressure based joining process.

An electronic device includes a leadframe having a die pad and leads. A die that includes an active layer is attached to the die pad. A reinforcement layer is disposed on the active layer and wire bonds are attached from the active layer of the die to the leads. A mold compound encapsulates the die, the reinforcement layer, and the wire bonds.

A printed circuit board includes: a printed wiring board including an insulating layer wherein a recessed part is provided on a top surface of the insulating layer, and a printed conductor provided inside the recessed part; a bare chip part mounted in the recessed part and electrically connected to the printed conductor; an electronic part mounted on the top surface of the printed wiring board other than the recessed part; and a cap fixed to the top surface of the printed wiring board and hollow-sealing the bare chip part mounted in the recessed part, wherein using a height of the top surface of the printed wiring board as a reference, a height of a top surface of the cap is equal to or below a maximum height of a top surface of the electronic part.

A bonding element includes a first transient liquid phase (TLP) bonding element including a first material and a second material, the first material having a higher melting point than the second material, a ratio of a quantity of the first material and the second material in the first TLP bonding element having a first value and a second TLP bonding element including the first material and the second material, a ratio of a quantity of the first material and the second material in the second TLP bonding element having a second value different from the first value.

The present disclosure relates to a hermetic package capable of handling a high coefficient of thermal expansion (CTE) mismatch configuration. The disclosed hermetic package includes a metal base and multiple segments that are discrete from each other. Herein, a gap exists between every two adjacent ceramic wall segments and is sealed with a connecting material. The ceramic wall segments with the connecting material form a ring wall, where the gap between every two adjacent ceramic wall segments is located at a corner of the ring wall. The metal base is either surrounded by the ring wall or underneath the ring wall.
