Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing an electronic component, in which the adherence of soldering dregs is fully prevented on the side of the component package, which needs to be prevented from being soldered. SOLUTION: A plastic package 14 or only a part of the plastic package having at least one metal soldering region 4 of the electronic component 1, is coated by a solder adhesion preventing layer 6, which mainly has siloxane, and is fixed on the plastic package 14 in the form of a solution without another solvent additive.

Abstract:
The invention relates to a varistor paste comprising a matrix material and particles embedded in the matrix material. Said matrix material has a viscosity of less than 0,8 Pa.s without the embedded particles. Said embedded particles comprise varistor particles.
Abstract:
An electronic, especially an optical or optoelectronic component is disclosed that comprises a part (6) containing a thermoplastic material (5) which has particles (1) including a core and a shell. The shell is arranged on the surface of the core, and the core contains aluminum.
Abstract:
The aim of the invention is to fix an optical lens above an optoelectronic transmitter or receiver. To this end, an epoxy resin, which is cationically hardened in a UV-initiated or light-initiated manner, is used with the aid of which the bonding joint hardens within a few seconds and can be thus be fixed. The invention also relates to the use of resin compositions as an adhesive. Said resin compositions can be applied as a liquid, are optically adapted, and are optimized for the durable and reliable use in optoelectronic components and for the large-scale manufacture thereof.

Abstract:
The invention concerns a surface mountable light diode light source, whereby the curvature of the leadframe required for surface mounting faces the rear side of the housing inside a transparent plastic shaped body. The invention also concerns a method for the production of a mixed light source, preferably a white light source based on a UV or blue emitting semiconductor LED (1), wherein the LED (1) is mounted on a leadframe (10), a transparent plastic molding compound (3) is mixed with a conversion material (4) and optionally other filling materials with the purpose of forming a molded compound and the leadframe (10) is reshaped with the molded compound in an injection process in such a way that the light exit sides of the LED (1) are surrounded by the molded compound.
Abstract:
The invention relates to an electronic component comprising, in predetermined areas, soldered regions that are arranged on at least one outer surface, whereby the component is coated on its surface that is not formed by the soldered regions with a layer that prevents the adherence of soldering agents thereto. The invention also relates to a coating agent for reducing the amount of solder tailings.
Abstract:
Disclosed is a wavelength-converting converter material comprising at least one wavelength-converting phosphor comprising phosphor particles, wherein a portion of said phosphor or all of said phosphor is present in the form of nanoparticles. Also disclosed is a light-emitting optical component comprising such a converter material and a method for producing such components.
Abstract:
A light-emitting semiconductor device has (a) a semiconductor body (1) with a layer sequence (7) capable of emitting electromagnetic radiation of a first wavelength range in the UV, blue and/or green region; and (b) a luminescence conversion element which converts radiation of the first wavelength range to radiation of one or more second, different wavelength ranges so that the device emits mixed radiation in the first and second wavelength ranges. Preferably, the luminescence conversion element consists of organic dye molecules in a plastic matrix preferably of silicone, thermoplastic or thermosetting material, especially an epoxide resin or polymethyl methacrylate matrix, and/or an inorganic phosphor (preferably a Ce-doped garnet, especially Ce:YAG) in an epoxide resin or low melting point inorganic glass matrix.
