Abstract: The disclosed invention relates to materials and processes for creating particle-enhanced bumps on electrical contact surfaces through stencil or screen printing processes. The materials are mixtures of conductive ink, conductive paste, or conductive adhesive and conductive hard particles (104). The process involves depositing the mixture (108) onto electrical contact surfaces by stencil printing, screen printing, or other dispensing techniques (110). In another embodiment, the ink, paste, or adhesive deposit. Once cured (114), the deposition provides a hard, electrical contact bump on the contact surface with a rough, conductive, sandpaper-like surface that can be easily connected to an opposing contact surface without any further surface preparation of either surface.

Abstract: A soldering process uses two or more different solder alloys. A first solder alloy (115) that undergoes a solid-to-liquid transition at a first temperature is coated (20) onto the solderable surfaces (105) of a printed circuit board (100). A solder paste (120) that undergoes this solid-to-liquid transition at a temperature greater than the first temperature is deposited on the coated solderable portions, and is heated to a temperature that is above the first temperature but below the second temperature. During this time, the first solder alloy liquifies, while the solder paste does not. The first solder alloy wets to the individual particles in the solder paste, and alloys to the solderable surfaces and the solder particles in the solder paste. The soldering composition is subsequently cooled (40) to solidify the first solder material, forming a solid and substantially planar coating on the solderable portions of the printed circuit board.

Abstract: A printed-wiring board has a copper foil (the first conductive layer) providing electric conductivity formed on one or both sides of an insulating board providing electrical insulation, an insulating layer providing electrical insulation formed at specific sites (where there are through-holes) on the first conductive layer, and a second conductive layer providing electric conductivity formed on the insulating layer. In this printed-wiring board, when the second conductive layer is formed, deposition of an electrically conductive material by plating, and polishing of the deposited electrically conductive material, these steps are repeated at least once, so that the surface of the second conductive layer can be smoothened to enhance the bonding stability of chip parts.
