Electrical component for monitoring the electronic assembly for surface mounting, electronic assembly with such an electrical component

摘要

The invention relates to an electrical component (12) for surface mounting, the component having electrical contacts (28) for contacting a circuit carrier (11). According to the invention, this component has a sacrificial structure (31) which is integrated between the electrical contacts (28) in an electrical connection. The sacrificial structure is sensitive to, for example, thermal influences or environmental influences, so that aging of the sacrificial structure can be tracked by measuring the properties of the electrical connection. For example, the sacrificial structure (31) can be a diffusion cell with a first phase (24) and a second phase (25). As soon as diffusion zones (27) form between these phases, the electrical resistance of the sacrificial structure changes in a measurable manner. The invention also relates to electronic assemblies in which such components are installed. Finally, the invention also relates to a method for operating such an electronic assembly.
