Abstract

Electronic apparatus, battery powerable apparatus, and radio frequency communication devices are disclosed. In but one implementation, an electronic apparatus comprises a substrate having a component mounted thereto. An encapsulant mass is received over and adheres to the gasifiable component and to the substrate. An opening is formed through the substrate and extends to the encapsulant mass. In another considered implementation, an electronic apparatus comprises a substrate having a component mounted thereto, with the component comprising a lateral periphery. An encapsulant mass is received over and adheres to the gasifiable component and to the substrate. An opening extends through the substrate from a location proximate the component within a region bounded by the component lateral periphery to externally of the substrate.
