A heating device for testing integrated components is disclosed. In one embodiment, an inner casing is arranged in the heating device surrounding a holding chamber. The inner casing contains at least one recess in which an electrically conductive contact device is moveably arranged. This permits contact to be reliably made with a circuit to be tested. If the inner casing is of compact design, there is a very homogeneous temperature distribution in the heating device.
