    Abstract: The present invention provides for a relatively simple method to decrease the electrical resistivity of conductive adhesives by in-situ nanoparticle formation and sintering using a reducing agent. The reducing agent was found to cause sintering within the conductive adhesive by facilitating the reduction of the silver salts of fatty acids on the surface of silver flakes, leading to the formation of nano-/submicron-silver necks. These silver necks bridge neighboring silver flakes, decreasing the contact resistance between flakes within the conductive adhesives. The reducing agent also removes at least a portion of the lubricant commonly found on silver flakes used in conductive adhesives, thus reducing the tunneling resistance between the silver flakes.

    Abstract: An electrical condition monitoring method utilizes measurement of electrical resistivity of a conductive composite degradation sensor to monitor environmentally induced degradation of a polymeric product such as insulated wire and cable. The degradation sensor comprises a polymeric matrix and conductive filler. The polymeric matrix may be a polymer used in the product, or it may be a polymer with degradation properties similar to that of a polymer used in the product. The method comprises a means for communicating the resistivity to a measuring instrument and a means to correlate resistivity of the degradation sensor with environmentally induced degradation of the product.

    Abstract: The present invention provides low stress non-hermetic conformal coatings for the protection of microelectronic devices, such as a Microelectromechanical system (MEMS) based multichip module from adverse environments. The induced stress from these two coatings due to the thermal cycling and manufacture processing will not cause any influence on sensing accuracy of the piezopressure sensor or similar functional MEMS devices. Furthermore, the conformal coatings have the merits of low glass transition temperature, good elongation, low moisture uptake and mobile ion permeation, room temperature curability and good contamination resistance to the jet fume, which promise a high reliability for the aerospace and avionics application. One conformal coating comprises a composition/formulation containing a rubber, siloxane or urethane oligomer modified epoxy and an organic hardener, and optionally an organic diluent and a curing catalyst. Another conformal coating comprises a composition/formulation containing a silicone elastomer or gel and a metal chelate catalyst, and optionally a silica filler, a diluent and an adhesion promoter or coupling agent.
