Abstract
A method for producing a surface mount device includes providing a plurality of layers including a B-staged top layer and bottom layer, and a C-staged middle layer with an opening. A core device is inserted into the openings, and then the top and bottom layers are placed over and under, respectively, the middle layer. The layers are cured until the layers become C-staged. The core device is substantially surrounded by an oxygen-barrier material with an oxygen permeability of less than approximately 0.4 cm3·mm/m2·atm·day.
