摘要:
A semiconductor component includes a semiconductor chip having contact pads on its main face, and a wiring foil, in which are recesses for the contact pads, applied to the main face. The foil has conductor tracks on a side facing away from the main side. The conductor tracks connect the contact pads to solder contacts. The contact pads located in the recess are electrically connected via wire connections to adjacent conductor track ends. Each wire connection is surrounded with a sealing compound of a first and a second layer. A method for manufacturing a semiconductor component includes applying wiring foil to a main side of the chip, producing the wire connection between contact pads and adjacent conductor track ends, applying sealing compound to locations on the recess to completely cover the wire connection with the sealing compound, and only curing the surface of the sealing compound.

An electrically conductive connection is produced between a chip and an external wiring configuration that is kept at a distance from the chip by spacers. Electrically conductive contact material is introduced into recesses in the external wiring configuration in order to produce the electrically conductive connection. This can be carried out economically, and allows a mechanically very robust electrical connection from the chip pads to the external wiring planes.

A method is described for applying an integrated circuit to a carrier element. In which a curable compensating layer of initially paste-like consistency is coated substantially with full coverage onto a lower contact area of the integrated circuit. Whereupon the integrated circuit is joined together, by the compensating layer, with the carrier element after a relative alignment in order then to produce an electrical connection between the integrated circuit and conductor tracks of the carrier element via electrical lines surmounting the thickness of the compensating layer. Whereupon the compensating layer is cured resulting in an increased volume of the compensating layer.

An electronic device is described that has a sheet strip for packaging bonding wire connections of the electronic device and a method for producing it. To that end, the sheet strip, has at least two preformed, opposite edge regions which cover the edge regions of the bonding channel in an overlapping manner. Furthermore, the sheet strip has a preformed central region situated between the edge regions, which central region has a bulge and thickened portion and has two convexly curved contour lines in cross section.

The lead frame has a spring element, which can be compressed during the injection molding of the package by an injection mold. The resultant resilience has the effect that a contact surface of the lead is pressed against an inside wall of the injection mold. The biasing of the contact surface against the inside wall prevents polymer flash from forming on the contact surface. Also, the spring element fixes the lead during the injection operation and anchors the lead in the completed package. Hold-down pins within the injection mold are thus obviated.

The electronic component has a semiconductor chip mounted to a wiring board. The chip is bonded to the wiring board with adhesive strips that leave free a through-cutout, an additional cutout, and separating joints. The additional cutout provides for a plastic reservoir from which the separating joint between the adhesive strips is filled with plastic material.

A method for the injector-individual adaption of the injection time of motor vehicles is based on linking the IIC method and the MFMA method. Before starting to drive, the IIC method is carried out, and while driving MFMA measurements are carried out. The measurement points obtained are used as subsequent measurement points for the IIC function. Thus injector-individual characteristic fields can be determined, in which deviations due to manufacturing and also aging and wear of the components during the service life are considered.

A tendency of the controlled load to oscillate when controlling a capacitive load can be avoided according to a piezo actuator for an injection valve of an internal combustion engine, having charging and discharging processes for charging and discharging the capacitive load by means of a load current, each loading process being effected by chronological partial load current pulses according to chronological partial charging capacity pulses (p1, p2, . . . pn), wherein the envelope (E) of the partial charging capacity pulses (p1, p2, . . . pn), during the loading process, increases in a strictly monotonous manner in an initial phase, and the slope of the envelope decreases in a monotonous manner.
