  • Patent number: 9695334
    Abstract: Oxygen barrier compositions for electrical devices and their related methods are provided. In certain embodiments, the oxygen barrier compositions comprise a meta-substituted aromatic resin and an additional aromatic epoxy resin. In some embodiments, the compositions have a chlorine content of less than approximately 1000 ppm. The compositions may have an oxygen permeability of less than approximately 0.4 cm3·mm/m2·atm·day at approximately 0% relative humidity and approximately 23° C. In certain embodiments, methods of curing the oxygen barrier compositions comprise partially curing the composition where, the partial cure is achieved through ultraviolet radiation or heat.

  • Patent number: 9029741
    Abstract: A surface-mountable electrical circuit protection device includes layers defining a first PPTC resistive element, a second PPTC resistive element, and at least one heat-generating electrical component such as a planar zener diode chip positioned between, and in thermal contact with, the first and second PPTC elements, such that an electrical current above a threshold level passing through the component causes the component to heat, the heat being transferred to the PPTC resistive elements and tripping at least one, and preferably both of the first or second PPTC elements to a high resistance state. A series of edge-formed terminal electrodes enable surface-mount connection of the first and second PPTC elements and the electrical component to an electrical circuit substrate, such as a printed circuit board. A method for making the device is also disclosed.

  • Patent number: 8525635
    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.
