Epoxy-based resin system composition containing a latent functionality for polymer adhesion improvement to prevent sulfur related corrosion

A method for producing an apparatus, comprising:

• providing an electronic component mounted on a substrate and electrically connected by metal conductors, wherein the metal conductors each have an upper termination layer with an upper surface;
• and
• covering at least a portion of the electronic component with an overcoat layer, wherein the overcoat layer overlies a first portion of the upper surface of the upper termination layer of the metal conductors and comprises an epoxy-based resin system;
• covering at least a portion of the overcoat layer with a protection layer, wherein the protection layer overlies a second portion of the upper surface of the upper termination layer of the metal conductors and comprises an epoxy-based resin system, wherein the overcoat layer and the protection layer together cover all of the upper surface of the upper termination layer of the metal conductors;
• wherein at least one of the overcoat layer and the protection layer is an epoxy-based resin system composition comprising:
• one or more epoxy-based resins, wherein at least one of the one or more epoxy-based resins includes a first epoxide functionality;
• one or more hardeners, wherein at least one of the one or more hardeners includes a first reactive functionality, and wherein the first reactive functionality and the first epoxide functionality react with each other at a first temperature;
• zero, one or more filler materials;
• wherein a latent functionality is contained in at least one of the one or more epoxy-based resins, the one or more hardeners, and the zero, one or more filler materials, wherein the latent functionality does not react at the first temperature, and wherein the latent functionality reacts in response to a stimulus comprising at least one of ultraviolet (UV) light and a second temperature greater than the first temperature.
