The present invention relates to a galvanic element, in particular an element of the button cell type, which has a long service life even when there are high mechanical or thermal loads. The element has a cathode, an anode, an electrolyte, a separator arranged between the anode and cathode, and a housing, which comprises a housing cup, a housing cover and a sealing element, the sealing element insulating the housing cup against the housing cover. According to the invention, the sealing element is rigidly connected to the separator.

Galvanic element for high stresses

The invention relates to a multilayer printed circuit board structure comprising a stack of plurality of electrically insulating and/or electroconductive layers and at least one passive or active electrical component arranged inside the stack of layers, the component extending laterally only in part of the surface extension of the stack of layers. The invention also relates to a passive or active electrical component mounted on the stack, to an associated wiring, and to a corresponding production method. According to the invention, the insert is embedded between two electrically insulating liquid resin layers or prepreg layers extending over the entire surface and covering the insert on both sides, the insert being surrounded by a resin material that is liquefied by compression or lamination of the structure. The invention structure can be used in printed circuit board technology.
