Integrated electrostatic discharge and overcurrent device

The present invention provides overvoltage protection. Specifically, the present invention provides a voltage variable material (VVM, 100) that includes an insulative binder (50) that is formulated to intrinsically adhere to conductive and non-conductive surfaces. The binder and thus the VVM is self-curable and may be applied to an application in the form of an ink, which dries in a final form for use. The binder eliminates the need to place the VVM in a separate device or for separate printed circuit board pads on which to electrically connect the VVM. The binder and thus the VVM can be directly applied to many different types of substrates, such as a rigid (FR-4) laminate, a polyimide or a polymer. The VVM can also be directly applied to different types of substrates that are placed inside a device.

PURPOSE:To provide a heat-resistant laminated stretched sheet improve in heat resistance, secondary moldability and rework properties (containing heat- resistant grade) and excellent in transparency, rigidity, toughness and cost performance. CONSTITUTION:A laminated stretched sheet consists of a surface layer formed from a mixed composition of a styrennic resin (10-95wt.%) and a polyphenylene ether resin (5-90 wt.%) and having thickness being 5-80% of the total thickness of the sheet and a inner layer composed of a resin based on a styrenic resin.

Thermoplastic resin laminated stretched sheet

PURPOSE:To obtain a stretched multilayer sheet having a wide molding temperature range and excellent deep drawing properties, by selecting thermoplastic resins so that the Vicat softening point of the resin constituting surface layers and the Vicat softening point of the resin constituting an inner layer are in a specified ratio, and arranging the resins in layers so that the total thickness of the surface layers has a specified proportion based on the total thickness of all layers. CONSTITUTION:A stretched multilayer sheets has surface layers and one or more inner layers, wherein a thermoplastic resin A constituting the surface layers and a thermoplastic resin B constituting the inner layers are so selected that the Vicat softening point (Va: deg.C) of the resin A and the Vicat softening point (Vb: deg.C) of the resin B have a ratio Va/Vb of at least 1.10, and the resins are arranged in layers so that the total thickness of the surface layers is 5-70% based on the total thickness of all of the layers. When the Vicat softening temperature ratio Va/Vb is less than 1.10, no improving effects can be obtained on the molding temperature range for the sheet, deep drawing properties of the sheet or on nonuniformity in the material thickness of molded products. When the percentage of the total thickness of the surface layers is less than 5%, the molding temperature range for the sheet is not broadened because the upper limit of the molding temperature is not raised sufficiently, as compared with that of a sheet of the resin constituting the inner layers. When the percentage exceeds 70%, the upper limit of the molding temperature remain unchanged and, rather, the lower limit of the molding temperature is raised, resulting in a narrower molding temperature range.
