Abstract: A pressure contact assembly includes a power substrate, a chip, and a lead. The power substrate has a surface connected to a ceramic tile and a cavity. The chip is soldered to the surface. The lead is to be inserted into the cavity and has a top portion to connect to an external device and a bottom portion to fit into the cavity.

Abstract: A lead-free power semiconductor package (PSP) includes a substrate, multiple copper leads, a die, and an encapsulant. The substrate has alternating layers of copper and silicon nitride. The copper leads, which are not part of a leadframe, are connected to the substrate using active metal brazing. The die, which contains circuitry to allow the PSP to operate, is connected to the substrate using silver sintered paste. The encapsulant encases the substrate and the die with a portion of the multiple leads being outside the encapsulant.

Abstract: A substrate assembly may include a power substrate, a chip, a clip, and a trimetal. The power substrate has a first direct copper bonded (DCB) surface connected to a ceramic tile. The chip is soldered onto the first DCB surface. The clip is attached to the power substrate and has a foot at one end and a recessed area at the other, opposite end. The foot is connected to the power substrate. The trimetal has a base, a trapezoid structure, and a clip portion. The base is soldered to the chip. The trapezoid structure is located above the base. The clip portion is located above the trapezoid structure and includes a projecting area. The recessed area of the clip fits into the projecting area of the trimetal.
