    Abstract: A method of forming a subassembly for use in a printed circuit board is described. This method includes providing a subassembly including a circuit board layer laminated to two sheets of conductive material with two intermediate sheets of prepreg material, forming a via in the assembly, plating the via, filling the via with a plug material in a volatile solvent, evaporating the volatile solvent, and curing the plug material. Also described is a method of forming a partially filled via in a circuit board layer and a method of forming a thermally conductive plug in a circuit board layer for the transfer of thermal energy from one surface of the circuit board to the other.

    Abstract: An apparatus for manufacturing a plug and the manufacturing method. The method includes the following steps. A baseplate located in the bottom of a closed printing chamber is provided. A printed circuit board and a stencil are mounted on the baseplate in sequence. The stencil is aligned to the printed circuit board. An amount of preheated paste is placed on the stencil. A pressure of the closed printing chamber is adjusted to a first pressure. A printing step is performed to form plugs in the printed circuit board. The pressure of the closed printing chamber is adjusted to a second pressure to remove voids trapped in the plugs. The pressure of the closed printing chamber is adjusted to a third pressure. A scraping step is performed to remove the redundant paste.

    Abstract: A liquid thermosetting filling composition comprising (A) an epoxy resin assuming a liquid state at room temperature, (B) a phenolic resin assuming a liquid state at room temperature, (C) a curing catalyst, and (D) an inorganic filler is useful as an ink for permanently filling such holes as via holes and through holes in printed circuit boards of a multilayer board or a double-sided board, a sealing compound for IC packages, and the like. This composition is a two-stage thermally curing type. In a method for permanently filling holes in a printed circuit board, the composition is applied to the board so as to fill the holes in the printed circuit board and precured by application of heat. The parts of the precured composition protruding from a surface defining the holes is removed by polishing and then the precured composition is further heated to cause final curing thereof.

    Abstract: A method for forming a planarized thin film dielectric film on a surface of a common circuit base upon which one or more integrated circuits are to be attached. The common circuit base includes raised features formed over its surface such that the raised features define a trench area between them. The method includes the steps of forming a first layer of the dielectric film over the common circuit base and over the raised features and the trench, then patterning the newly formed layer to remove portions of the layer formed over the raised features and expose the raised features. After the layer is patterned, formation of the dielectric film is completed by forming a second layer of the dielectric film over the patterned first layer. Additional film deposition and film patterning steps are performed to complete the layout of a thin film interconnect structure over said common circuit base, and an integrated circuit die is attached to the common circuit base and electrically connecting to the thin film interconnect structure. In a preferred embodiment, the first and second layers of the dielectric film are both formed from a photo-definable material and the patterning step includes exposing the first layer to light through a patterned mask corresponding to the raised features and developing the exposed layer with a developing solution to etch away portions of the first layer formed over the raised features.
