The present idea refers to a needle head, its use in a probe arrangement, and a method for electrically contacting multiple electronic components. The needle head comprises a body with a lower surface, needle electrodes emerging from the lower surface, and multiple outlets arranged in the lower surface. A channel is arranged between an inlet in the body and the outlets for conveying a medium from the inlet to the outlets. By this means, electronic components arranged in close distance under the lower surface of the needle head are directly exposed to the medium which provides a test environment during a test of the electronic components.

To process a plurality of sensor devices, such as humidity sensors or gas sensors, the sensor devices are run through a testing station and a turret handler. In order to increase throughput of the testing station, several test cycles are operated simultaneously in a phase-shifted manner. The sensor devices are e.g. sequentially fed onto trays of the test station, on which they are assembled in batches. Each batch is subjected to a test cycle. After the test cycle, the sensor devices of a batch are sequentially fed back to the turret handler.
