摘要:
An apparatus and a method for measuring operating temperatures Tj of a component, particularly transient temperatures Tj in the breakdown region of the component 2 during a breakdown operation, are provided. The component temperature Tj at a point of time ti is ascertainable from a measurement of the breakdown voltage Ud and the breakdown current I of the component 2 at the specific point of time ti during the breakdown operation using a measuring device, by comparing the measurement data to reference measurement data recorded in advance.

摘要:
Two DBC wafers have patterned first conductive surfaces which receive a semiconductor die in sandwich fashion. Lead frame terminally extending into the package interior and are connected to the die terminals. The outer conductive surfaces of each of the wafers are available for two-sided cooling of the semiconductor.
摘要:
A connecting device for contacting a semiconductor component to at least one further component, the connecting device comprising at least one metal connecting strip extending in a longitudinal direction and having a contact region for mounting on a terminal region of the semiconductor component. In order to achieve a contacting system that can be manufactured inexpensively but can nevertheless carry high current densities, a connecting device is proposed whose contact region is embodied in structured fashion and flexibly with respect to stresses that extend in a terminal plane parallel to the terminal region.
摘要:
The power switches of an inverter are mechanically integrated with an electric motor of a vehicle and are mounted on the end plate of the motor and employ short connections between the motor a-c terminals and the inverter a-c output terminals. Bond wireless modules are employed. The electronic controls for the inverter are mounted on a main control board which is positioned remotely from the inverter and is not subject to the heat and EMI produced by the inverter.

摘要:
A substrate on which a silicon device is mounted in accordance with an embodiment of the present invention includes a plurality of protrusions extending upward from a top surface of the substrate and a solder layer formed on the top of the substrate such that the plurality of protrusions extends through the solder layer and a top portion of each protrusion of the plurality of protrusions is stamped down to be level with a top surface of the solder layer such that the silicon device is supported on the plurality of protrusions when placed on the substrate. The protrusions are preferably gouged up from the surface of the substrate with a needle like tool. A stamper tool is used to stamp the protrusions down to their desired height such that they are properly positioned to support the silicon device. The solder layer may be a solder pre-form or may be a layer of solder paste. The solder layer is heated to form liquid solder to bond the substrate and the silicon device, however, the protrusions support the silicon device to prevent movement thereof when the solder is in liquid form.
摘要:
A semiconductor device package is formed of DBC in which thinned MOSgated and/or diode die are soldered to the bottom of an etched depression in the upper conductive layer. A via in the insulation layer of the DBC is filled with a conductive material to form a resistive shunt. Plural packages may be formed in a DBC card and may be separated individually or in clusters. The individual packages are mounted in various arrays on a support DBC board and heat sink. Integrated circuits may be mounted on the assembly and connected to the die for control of the die conduction.
