In order to test, in particular, BGA (Ball Grid Array) contacts, the free contact pin end is formed as a suction tube in which a reduced pressure that acts on the end area of the free contact pin end can be produced. If the diameter of the suction tube is less than the diameter of the component contact with which contact is to be made, a mechanical and electrical contact can be produced by sucking an approaching component contact onto the end area of the contact pin end, without having to exert pressure on the rear face of the component.

A process and device for calibrating a semiconductor component test system includes a first connection, at which a corresponding signal, in particular a calibration signal can be input, and a second and third connection, at which the signal, in particular a calibration signal, can be emitted. The first connection is and/or can be connected via a corresponding line to a first switching apparatus, which is and/or can be connected to the second connection. A second switching apparatus is and/or can be connected to the third connection. Advantageously, the signal is then transferred to the second connection, and barred from the third connection by the first switching apparatus being closed and the second switching apparatus being opened.

Test apparatus for testing an integrated circuit The invention relates to a test apparatus for testing an integrated circuit, particularly a DDR semiconductor memory, having at least one data connection for inputting at least one data signal, at least one DQS control connection for inputting at least one unaltered-frequency DQS signal, a device for phase shifting which is designed to take the unaltered-frequency DQS signal and produce a phase-shifted DQS signal, and a combinational logic device which is connected downstream of the device and which logically combines the unaltered-frequency DQS signal with the phase-shifted DQS signal to produce an altered-frequency DQS signal which has a frequency that is increased compared with the frequency of the unaltered-frequency DQS signal and which is provided for latching the data signals or as a clock signal. The invention also relates to a method for operating a test apparatus of this type.
