    Abstract: Embodiments of the present invention are directed to methods and structures providing completely filled electrical interconnections, or vias, that are disposed through a surface land mounting area, or pad, on a dielectric substrate (104). A via (100) includes a first conducting layer (106) on the inner surface (102c) of a via hole. The via hole is filled with a thermally conductive material (110) with a desired viscosity and/or thixotropic ratio. The via fill material may be a metal powder in an epoxy matrix. The dielectric substrate may be used in rigid and/or flexible circuit components such as PWBs. High levels of surface land co-planarity, or surface flatness for pads on such substrates may be achieved by the use of conductive layers formed by immersion processes. Aspects of the invention may provide reduced amounts of lead (Pb) or eliminate lead altogether from a substrate.

    Abstract: The present invention relates to a method of providing thermal vias in a printed circuit board that includes one or more layers of board material, for conducting heat from components mounted on and/or in the board through said board through said board and away therefrom, and also relates to a printed cirucit board that includes vias arranged in accordance with method. One or more holes (4) are provided in a printed circuit board that includes several metal layers. A metal ball (6) is inserted into each hole and subjected to pressure such as to deform said ball, and tightly fixating the resultant slug against the wall (5) of said hole. The deformed ball or slug fixed in the hole, which may have a metallised inner surface, functions to conduct heat and/or electricity between a metallised topside (2) and bottom side (3) of the printed circuit board and also between intermediate metallised layers in the case of a multi-layer board.

    Abstract: A liquid thermosetting resin composition comprising (A) an epoxy resin, (B) a curing catalyst, and (C) a filler, which is characterized by exhibiting a viscosity of 1500 dPa s or below at 25 DEG C, a gel time of 300 s or above at a temperature at which the composition exhibits a melt viscosity of 10 dPa s or below, and a gel time of 600 s or below at 130 DEG C. In producing a printed wiring board by forming an interlayer dielectric layer of a resin and a conductive circuit on the surface of a wiring substrate having a conductive circuit pattern including holes, the holes are plugged by filling the holes with the above composition, precuring the resulting composition by heating, abrading and removing the protrusions of the composition from the surface, and curing the remaining composition completely by additional heating. Thus, the via holes or through holes of a printed wiring board can be plugged with good workability.
