The invention discloses an electrical component with a carrier substrate, on which at least one semiconductor chip is mounted. Terminal areas are arranged on the underside of the carrier substrate and contact areas designed for the assembly with semiconductor chips are arranged on the upper side. The carrier substrate has a functional area that is divided into sections, wherein each section is assigned at least one function such as, e.g., as a filter, a frequency-separating filter, a balun, etc. A separate area of the carrier substrate is assigned to each section. The following applies to at least one of the sections: the contact area and/or the terminal area that is conductively connected to the section lies outside the base of this section. The connecting line that conductively connects the input or output of the respective section to the contact area and/or the terminal area is preferably shielded from the section by a ground area.

Abstract:
A new SMD (surface mount devices) package design for efficiently removing heat from LED Chip(s) is involved in this invention. Different from the regular SMD package, which electrical isolated materials like Alumina or AlN are used, the substrate material here is metal like Copper, Aluminum and so on. Also, different from regular design, which most time only has one LED chip inside, current design will at least have two or more LED chips (or chip groups) in one package. All chips are electrical connected via metal blocks, traces or wire-bond. This type of structure is generally fabricated via chemical etching and then filled with dielectric material inside to form a strong package. Because the thermal conductivity of the metal is much higher than the ceramics, the package thermal resistance is much lower than the ceramics based package. Also, the cost of the package is much lower than ceramics package. Moreover, emitting area in one package is much larger than the current arts.
