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 method and apparatus are disclosed for enabling automated printing of through holes extending between top and bottom surfaces of a ceramic substrate or the like. The perimeter of the substrate is placed on a support that locates the bottom surface of the substrate spaced from a member that interacts with the interior portion of the substrate. The interacting member has holes that correspond to the through holes in the substrate, and it is moved generally perpendicular to the substrate to a position where it is in juxtaposition with the bottom surface of the substrate and its holes are in registration with the holes in the substrate. Conductive material is applied to the top surface of the substrate and a vacuum is applied to the holes in the interacting member to pull the conductive material through the through holes in the substrate. The vacuum is then discontinued and the interacting member is moved back to a position where it is spaced from the bottom surface of the substrate.

摘要： Improved encapsulated, overmolded and/or underfilled electrical components having a complete encapsulation, overmolding and/or underfilling with a coefficient of thermal expansion that is uniform and substantially free of gradients includes a polymeric matrix and an inorganic filler having a platelet geometric structure. The platelet structure of the filler allows a desirable coefficient of thermal expansion to be achieved using a very low level of filler material. This low level of filler material facilitates lower viscosity during forming of the encapsulation and/or overmolding, thereby facilitating complete filling of a mold cavity and underfilling of space between a circuit board and a semi-conductor chip electrically connected to the circuit board. In addition, the low viscosity has processing advantages that reduce the potential for damage to electrical components during encapsulation, overmolding and/or underfilling.

The assembly further includes a localized stiffener attached to a second surface of the laminate substrate so as to be directly opposite the circuit device. The localized stiffener is formed of a material and is shaped so that, when attached to the laminate substrate, the stiffener is capable of increasing the thermal cycle fatigue life of the one or more solder joints that attach the device to the substrate.
