Abstract: An electric PCB heating component for a heating electric component is coupleable to an electronic circuit board. The PCB heating component includes a fastening element, a heating element for generating thermal energy, and a heating body. The heating body emits thermal energy via a heat radiating surface.

The heating projections can be convection or radiation elements.

Abstract: Functional elements, particularly PTC heating elements, are braced in a hollow reception means, such as a profile tube. The reception means have two at least partly concave top wall areas facing one anther and flat sides of the functional elements and in this way permits a bracing of the functional elements, in that side walls of the reception means, extending substantially perpendicular to the concave top wall areas, are subject to the action of a pressing pressure. In the free space areas defined by the concave top walls can be fitted ends of attachment parts, such as metal lamellas, which are clamped in the same operation, according to the invention, during the bracing of the functional elements. This makes it possible in a simple manner to manufacture assembled devices, particularly electric heating devices.

Abstract: A semiconductor wafer is held by support pins horizontally. A susceptor and a heating plate are moved upwardly so that the semiconductor wafer is transferred from the support pins to the susceptor. At this time, a gas layer is sandwiched between the upper surface of the susceptor and the lower surface of the semiconductor wafer to cause the semiconductor wafer to float over the upper surface of the susceptor for about seventy seconds immediately after the semiconductor wafer is mounted on the upper surface of the susceptor. Then, flash lamps are lit up to perform flash heating while the semiconductor wafer is floating over the upper surface of the susceptor. Even when flashlight irradiation causes rapid thermal expansion of the wafer surface, the semiconductor wafer does not suffer a great stress. This can prevent the semiconductor wafer from breaking.
