AI Technical Summary

Problems solved by technology

The bonding process and soft potting require multiple heating processes for pre-drying and hardening the adhesive and potting, which results in long manufacturing process times
Furthermore, the development of the module housing requires relatively high development effort
In addition, high investment costs arise for the injection mold and for the machine for automatic plug-in assembly of electronic modules

Abstract

The invention relates to a carrier (3) for at least one electrical component (5 to 7). The carrier (3) comprises: a heat sink (11) having a heat sink surface (31) and two opposite side walls (25) protruding from the heat sink surface (31); two sealing blocks (13) which lie flat on the cooling body surface (31) and are spaced apart from each other, each of which extends between the two side walls (25) and abuts against each of the two side walls (25); and a carrier structure (15) for at least one electrical component (5 to 7), which is arranged on the cooling surface (31) between the two sealing blocks (13).

Description

technical field [0001] The invention relates to a carrier for at least one electrical component, a method for producing such a carrier, and an electronic module. Background technique [0002] Manufacturing of electronic modules with power semiconductors such as IGBTs (bipolar transistors with insulated gates, English: insulated-gatebipolar transistors) or MOSFETs (metal-oxide-semiconductor field-effect transistors, English: metal-oxide-semiconductor field-effect transistors) is complex and expensive. In order to meet the high insulation requirements in such electronic modules, the semiconductor chip and the bonding wires are covered with a potting compound (eg silicon-based soft potting compound). The potting compound additionally prevents the ingress of moisture and corrosion of the components. During infusion, the infusate is very thin. In order to achieve good wetting and avoid foaming, the infusion is performed at a small low pressure. The outflow of potting compound...
