Conductive adhesives are important in surface mount technology industry as a means of attaching surface-mount components to a substrate. The most familiar conductive epoxy is essentially a polymer adhesive material with metal fillers that provide the conductivity of material. In surface-mount assembly, the epoxy is either stenciled or syringe-deposited on pads like solder paste. After components are placed into the material, a thermal cure occurs. The cure schedule varies with the material properties but is typically between 80° to 100° Conductive epoxies provide good tensile strength, particularly when the application resides at extreme temperatures.
