    摘要: Embodiments include an interconnect or trace of electrically conductive material with a contact surface, and a dielectric layer overlying the contact surface with a via formed on the dielectric layer and to the contact surface. The via sidewalls and perimeter are layered with a manganese oxide (MnO2) layer which is layered over with a conductive polymer material. An interconnect material is formed in the via and in a trench above the perimeter of the via such that the interconnect material is on the conductive polymer material and contacts the contact surface. An additional dielectric layer may be formed over the interconnect material and an additional via may be formed therethrough so that an additional structure having a MnO2 layer, conductive polymer material, and interconnect material can be formed in the additional via and to the interconnect material.

    摘要: A printed wiring board comprising conductive layers separated by nonconductive material and having through holes or other nonconductive surfaces on which an electrically conductive carbon coating is formed. The conductive carbon coating includes electrically conductive carbon having a mean particle size not greater than about 1 micron and a water-dispersible organic binding agent. The conductive carbon coating formed on the nonconductive surfaces has a low electrical resistance and is tenacious enough to be plated and exposed to molten solder without creating voids or losing adhesion.

    摘要: A method of applying a conductive carbon coating to a non-conductive surface and a printed wiring board having through holes or other nonconductive surfaces treated with such carbon coatings are disclosed. A conditioning agent is applied to the non-conductive surface to form a conditioned surface. A liquid dispersion of electrically conductive carbon (for example, graphite) having a mean particle size no greater than about 50 microns, combined with an organic binding agent, is coated on the conditioned surface to form an electrically conductive carbon coating. The conductive carbon coating is then optionally fixed on the (formerly) nonconductive surface and dried. The resulting coating has a low electrical resistance and is tenacious enough to be plated and exposed to molten solder without creating voids or losing adhesion, yet is easily removable from copper surfaces of the substrate by microetching.

    摘要: A method for preventing a carbon dispersion from increasing in viscosity during use is described. The dispersion comprises graphite particles or carbon black particles or a combination of both dispersed in a fluid. The method involves lowering the susceptibility of the carbon dispersion to an increase in viscosity or ionic strength by lowering its pH or reducing its exposure to reactive components in the ambient atmospheric gas. The pH can be lowered by at least partially removing ammonia from the dispersion, or by adding a material that reduces the pH of the dispersion. The stability of the dispersion can also be improved by isolating the dispersion from reactive atmospheric gas. The stabilized aqueous carbon dispersion can have a viscosity of less than about 20 cps and a conductivity of less than about 3 mS.

    摘要: A method of applying a conductive carbon coating to a non-conductive layer, conductive carbon compositions, and a printed wiring board having through holes or other surfaces treated with such carbon compositions are disclosed. A board or other substrate including at least first and second electrically conductive metal layers separated by a non-conductive layer is provided. The board has a recess extending through at least one of the metal layers into the non-conductive layer. The recess has a non-conductive surface which is desired to be made electrically conductive. The carbon in the dispersion has a mean particle size no greater than about 50 microns. The method is carried out by applying the carbon dispersion to a non-conductive surface of the recess to form a substantially continuous, electrically conductive carbon coating. Optionally, the coating is then fixed, leaving the carbon deposit as a substantially continuous, electrically conductive layer. Chemical and physical fixing steps are disclosed. The resulting coating has a low electrical resistance and is tenacious enough to be plated and exposed to molten solder without creating voids or losing adhesion.

    摘要: The present invention is directed to an improved composition and process for preparing a non-conductive substrate for electroplating. The composition comprises 0.1 to 20% by weight graphite having a mean particle size within the range of 0.05 to 50 microns; 0.01 to 10% by weight of a water soluble or dispersible binding agent for binding to the graphite particles; an effective amount of an anionic dispersing agent for dispersing the bound graphite particles; a pH within the range of 4-14; and an aqueous dispersing medium. Optionally, the composition may contain an amount of a surfactant that is effective for wetting the through hole. The resulting graphite dispersion is capable of uniformly coating the through holes in either a double-sided or multi-layer circuit board prior to electroplating. Through holes that were treated with the disclosed graphite dispersion prior to electroplating were free of visible voids after electroplating.

    摘要: A process is described for manufacturing through-hole plated single-layer or multi-layer printed circuit boards based on a polymeric substrate material or on a ceramic material provided optionally on both sides with at least one photoresist layer temporarily exposing the electroconductive circuit pattern by electroplating or electroless plating with a metal layer also on those surfaces which have not been coated with a conductive metal layer, characterized in thata) the surfaces of the substrate, after hole-drilling and a subsequent mechanical surface-treatment, are laminated with a suitable photoresist, exposed to light and developed so that the circuit pattern image is exposed,b) the surfaces of the substrate are pre-treated in a solution having oxidizing activity,c) after removal of the residual solution by rinsing, the substrate is introduced into a solution which contains at least one heterocyclic monomer, and more specifically pyrrole, thiophene, furane or derivative(s) thereof, which in a polymeric form is electrically conductive,d) the substrate is then transferred into an acidic solution whereby an electrically conductive polymeric layer is formed,whereupon, if desired or required, any residual solution is removed by rinsing, and the through-holes and the circuit pattern image are metallized in one step by galvanic or, preferably, electroless metallization.
