Abstract:
A thermal management system for an electrical component includes a printed circuit board (PCB) capable of receiving the electrical component on a first side of the PCB. An elongate member has one end attached to a second side of the PCB, and another end disposed away from the PCB. The elongate member also has an open interior that facilitates fluid communication between the two ends. One of the ends defines an at least partially closed boundary on the PCB. The PCB includes an aperture disposed therethrough proximate the boundary such that fluid communication is facilitated between the first side of the PCB and the second side of the PCB, and along at least a portion of the elongate member.

Abstract:
The present invention relates to methods and arrangements for forming a solder joint connection. One embodiment involves an improved solder ball. The solder ball includes a perforated, metallic shell with an internal opening. Solder material encases the shell and fills its internal opening. The solder ball may be applied to an electrical device, such as an integrated circuit die, to form a solder bump on the device. The solder bump in turn can be used to form an improved solder joint connection between the device and a suitable substrate, such as a printed circuit board. In some applications, a solder joint connection is formed without requiring the application of additional solder material to the surface of the substrate. The present invention also includes different solder bump arrangements and methods for using such arrangements to form solder joint connections between devices and substrates.

Abstract:
Multiple small conductive and flexible hollow rings, each of which is made from a pliable material, provide a flexible connection medium for use between a substrate and a microelectronic device package. Each ring is soldered to both the substrate and the device. A portion of the sidewall of each ring is not soldered thus insuring that at least part of the ring stays flexible. The rings accommodate elevation differences on a substrate and electronic device package. They also provide a vibration resistant and flexible joint.
Abstract:
A solder ball achieves a desired quantity of solder material for a solder joint easily without increasing the thickness of a solder layer formed to cover a core. The solder ball comprises a conductive core having depressions on its outer surface, and a solder layer formed to cover the outer surface of the core in such a way as to fill the depressions of the core. Thus, the quantity of the solder material included in the ball is supplemented by the solder material filled into the depressions. Preferably, the core has a higher melting point than the solder layer and wettability to the solder layer. The core may have a cavity in its inside, thereby forming a shell-shaped core. The core may be made of a porous metal body having pores, in which part of the pores reaches the outer surface of the core, thereby forming the depressions.
