A surface of the encapsulant is substantially coplanar with a plurality of surfaces of the electrical contacts.

A placement base (100) of a semiconductor device (90) comprises a body (10) on which the semiconductor device (90) is disposed, and a fixing unit (40) for fixing the semiconductor device (90) to the body (10). The body (10) has a supporting unit (12) and a bottom surface (11) placed in an inner periphery of the supporting unit (12) and placed lower than the supporting unit (12). A difference in height ΔH between the supporting unit (12) and the bottom surface (11) is larger than a sum (H1+H2) of a calculated or measured maximum upward warp H1 of the bottom surface (11) and a calculated or measured maximum downward warp H2 of a base of the semiconductor device (90).

The thermal interface materials may be applied to a wide range of substrates and components, such as lids or integrated heat spreaders of integrated circuit (IC) packages, board level shields, heat sources (e.g., a central processing unit (CPU), etc.), heat removal/dissipation structures or components (e.g., a heat spreader, a heat sink, a heat pipe, a vapor chamber, a device exterior case or housing, etc.), etc.

Embodiments may relate to a microelectronic package that includes an integrated heat spreader (IHS) coupled with a package substrate. The microelectronic package may further include a sealant material between the package substrate and the IHS. The sealant material may be formed of a material that cures when exposed to ultraviolet (UV) wavelengths. Other embodiments may be described or claimed.

Embodiments may relate to a method of forming a microelectronic package with an integrated heat spreader (IHS). The method may include placing a solder thermal interface material (STIM) layer on a face of a die that is coupled with a package substrate; coupling the IHS with the STIM layer and the package substrate such that the STIM is between the IHS and the die; performing formic acid fluxing of the IHS, STIM layer, and die; and dispensing, subsequent to the formic acid fluxing, sealant on the package substrate around a periphery of the IHS.

A heat dissipation structure including a plurality of heat dissipating members, and a support plate for supporting the heat dissipating members. Each of the heat dissipating members includes a plurality of cushion members each having a hollow or a solid shape, and a heat conduction sheet covering an outer surface of the cushion members. The support plate includes a plurality of grooves for supporting the heat dissipating members in a direction orthogonal to a longitudinal direction of the heat dissipating members. Each of the grooves is a curved recess portion formed in a thickness direction, opened to the side of the heat dissipating member, formed to have a radius of curvature larger than a radius of curvature of the heat dissipating member, and to have a depth smaller than a circular conversion diameter of the heat dissipating member, and a battery provided with the heat dissipating structure.

A cooling system for a circuit board includes a conforming layer that conforms to the profile of the circuit board, including a base and at least one heat generating component. A cap is connected to the conforming layer and offset from the conforming layer with a gap. A working fluid is flowed through the gap and used to cool the heat generating component. This allows for a low-cost and flexible cooling system for a circuit board without a redesign of a cold plate with each change to the circuit board.

A heat dissipation structure, for a heat-generating electric component, includes: a heat dissipator disposed along a surface of the electric component; and a porous material held between the electric component and the heat dissipator. The porous material of the heat dissipation structure is impregnated with heat-transfer fluid. The heat-transfer fluid may include liquid metal.
