Abstract

A method for producing vaporizer units as a component of inhalers includes the steps: a) providing a flexible circuit board material with sites for individual vaporizer units, the material optionally prestructured with conductor paths and/or pre-punched areas predetermined in terms of position/course for each site; b) providing and placing a heating element which may be electrically connected to the conductor paths; and c) at least partial covering each site with a sealing material for the formation of a partial sheathing for each vaporizer unit. The sealing material is applied such that the sheathing covers an edge region of the heating element while keeping open a heating surface on an upper side of the circuit board material. At least the outer surfaces of the sheathing pointing away from the circuit board material form sealing surfaces. Vaporizer units, vaporizer assemblies, vaporizer cartridges and inhalers with such vaporizer units are also provided.
