摘要： A PTC heating element and an electric heating device containing such a PTC heating element are disclosed. The PTC heating element comprises two insulating layers with a metallic coating provided on one side and a PTC element arranged therebetween which is provided on oppositely disposed main side surfaces with a respective metallization which is electrically conductively connected to the coating of one of the insulating layers. The metallization provided on one of the main side surfaces is assigned only to one potential for energizing the PTC element. The metallization provided on the other main side surface is assigned to only the other potential for energizing the PTC element. The metallization of the one main side surface of the PTC element and the metallization of the other main side surface of the PTC element are formed in such a way that the current path (P) through the PTC element is extended relative to the thickness (D) of the PTC element.

摘要： A test wafer is placed inside a baking module and is baked. Via one or more temperature sensors, a cumulative heat amount delivered to the test wafer during the baking is measured. The measured cumulative heat amount is compared with a predefined cumulative heat amount threshold. In response to the comparing indicating that the measured cumulative heat amount is within the predefined cumulative heat amount threshold, it is determined that the baking module is qualified for actual semiconductor fabrication. In response to the comparing indicating that the measured cumulative heat amount is outside of the predefined cumulative heat amount threshold, it is determined that the baking module is not qualified for actual semiconductor fabrication.

摘要： The invention relates to a heating module comprising a resistive heating element placed in a frame. The heating module constitutes a ready heating subassembly for heating a gas or a liquid, in particular for heating the air. The heating element is mounted to the frame by means of the at least two contacts arranged at opposite side walls of the heating element, wherein each contact comprises at least two brackets releasably coupled to a side wall, and at least one resilient element connected to the brackets and to at least one catch releasably coupled to the frame, wherein each resilient element, arranged in contact with a side wall of the heat ing element, is tensioned and exerts an expanding force acting on the connection of the contact with the frame and the heating element.

摘要： An electric heating device has several PTC heating elements that are arranged in a circulation chamber. The electric heating device includes a heating element casing which fits as a structural unit at least one PTC element and contact plates that energize said PTC element and form contact strips for an electrical plug connection. A partition wall separates the circulation chamber from a connection chamber in which the contact strips of the PTC heating element penetrating the partition wall are exposed and are electrically connected. A plug connection is formed between the partition wall and the PTC heating element and via which the PTC heating element is held in a frictionally engaged and/or in positive fit manner on the partition wall in the direction of insertion.

摘要： The aerosol-generating device includes a housing, and a power supply configured to supply electrical power to a heating element by way of a transformer assembly within the housing. The transformer assembly includes a magnetic flux guide, a primary circuit including a primary winding extending around a first portion of the magnetic flux guide and electrically connected to the power supply, and a secondary circuit including a secondary winding inductively coupled to the primary winding and extending around a second portion of the magnetic flux guide. The number of turns in the primary winding is greater than the number of turns in the secondary winding. The secondary circuit includes at least two electrical contacts configured to form an electrical connection with the heating element.
