A tamper-evident credential has a radio frequency identification (RFID) package with a first antenna and a subordinate antenna, RFID package defining a first part of the credential. The credential also has a subordinate RFID package defining a second part of the credential. The subordinate RFID package selectively coupled to said subordinate antenna so that an interrogation signal applied to said first antenna package is transmitted to the subordinate RFID package across said subordinate antenna.

In various aspects of the disclosure, a chip card module is provided. The chip card module may include a flexible substrate having a metallization on a first and second major surface, or side, thereof. An integrated circuit affixed to the second side is oriented with chip pads facing away from the substrate. Wire bonds may connect the chip pads to the metallizations.
摘要:
Data carrier for contactless data transmission comprising a substrate, a chip having at least one connection pad, wherein the chip is arranged by its side remote from the connection pad on the substrate and a first copper-coated prepreg layer is arranged on the chip and at least partly on the substrate and has a contact opening to the connection pad. A plated-through hole is situated within the contact opening for producing an electrically conductive connection between the connection pad of the chip and the copper layer of the first copper-coated prepreg layer, wherein a first antenna structure is formed in the copper layer of the first copper-coated prepreg layer.
摘要:
A chip card module is disclosed. The module includes an antenna carrier defining an antenna layer with at least one antenna disposed on a surface of the antenna carrier. A chip package defines a package layer different from the antenna layer in that the chip package encapsulates an integrated circuit chip packaged separately from the antenna layer. The chip package is attached to the antenna carrier and electrically connected to the antenna, forming a laminated structure.

A semiconductor component including: a substrate, at least one semiconductor chip arranged on the substrate and at least one passive device likewise arranged on the substrate. The passive device is mounted with its underside on the substrate. The semiconductor component further includes an interspace disposed between the underside of the passive device and the substrate. The interspace is filled with an underfilling material. In order to avoid the solder pumping effect, the upper side and the lateral sides of the passive device are also embedded in a plastic compound.

A method of assembling a semiconductor device includes providing a chip attached to an elastic carrier, and supporting the elastic carrier with a stiffener. The method additionally includes removing the stiffener from the elastic carrier after attaching the elastic carrier to a board.
摘要:
A cooling system for devices having power semiconductors and a method for cooling the device is disclosed. In one embodiment, the cooling system has printed circuit boards arranged on a circuit carrier in plug-in contact strips. The cooling system itself has a cooling plate, which is mounted in a pivotable manner on one of the plug-in contact strips in the region of the power semiconductor component. The cooling plate can be pivoted about an axis in such a way that it assumes a first position, which is pivoted away from the printed circuit board, and a second position, in which the cooling plate bears on the power semiconductor component.

摘要:
A semiconductor device includes a plastic housing and a semiconductor chip, wherein the semiconductor chip includes an active top side and a rear side. An interposer is arranged on the active top side of the semiconductor chip. At least a portion of the interposer is embedded into the plastic housing, while the top side of the interposer forms the top side of the semiconductor device. A top side fitting shape is arranged on the top side of the interposer, where the top side fitting shape has a predetermined radius of curvature that is free of plastic housing composition, and the top side fitting shape has a convex or concave lens-shaped sphere segment shape.
