摘要： An optical information processing circuit assembly includes an optically transmissive substrate and a resiliently compressible circuit member affixed to the substrate and defining an opening therethrough with a number of leads disposed about the opening. An integrated imaging circuit defines a corresponding number of pads wherein the pads align with and electrically contact the leads. An optically transmissive medium may be disposed between and in contact with the substrate and the integrated imaging circuit to allow light transmission therethrough from the substrate to the imaging circuit. In one embodiment, resilient bumps are provided between the integrated imaging circuit and the resiliently compressible circuit member to form the electrical connection therebetween. Alternatively, solder bumps may replace the resilient bumps. Additional circuit components may be similarly mounted to the resiliently compressible circuit member to complete the assembly.

摘要： An encapsulation material suitable for dissipating heat generated by an electronic module, such as by directly contacting a heat-generating power device or contacting a heat sink of a heat-generating power device. The encapsulation material comprises phase change particles dispersed in a gel material. The phase change particles preferably comprise a solder alloy encapsulated by a dielectric coating so the phase change particles are electrically insulated from each other. The encapsulation material may further comprise dielectric particles dispersed in the gel material for the purpose of increasing the thermal conductivity of the encapsulation material. Alternatively or in addition, the dielectric coating on the phase change particles may comprise dielectric particles that are dispersed in a dielectric matrix, again with the preferred effect of increasing the thermal conductivity of the encapsulation material.

摘要： A process for underfilling a bumped die surface using a lamination step and compound film such that solder bumps on the die are exposed during lamination. The compound film comprises a first layer containing an underfill material and a second layer on the first layer. The underfill material and the second layer comprise polymer materials that differ from each other. The compound film is laminated to the die, preferably at the wafer level, so that the underfill material is forced between the solder bumps and fills spaces between the bumps but does not cover the bumps. In contrast, the second layer covers the solder bumps, but is then selectively removed to re-expose the solder bumps and the underfill material therebetween.
