    Abstract: An example device may comprise a molded structure and a dependent device coupled to the molded structure. The molded structure comprises thermo-electric traces and channels. The channels are between ten μm and two hundred μm, or less in one dimension. The dependent device comprises apertures corresponding to the channels and through which fluids, electromagnetic radiation, or a combination thereof is to travel. The dependent device also comprises contacts corresponding to the thermo-electric traces of the molded structure.

    Abstract: Aspects of the present disclosure are directed to forming a layer of material on a print head. As may be implemented in a manner consistent with examples herein, a layer of material from a transfer film is pressed against a surface of a print head, in which the surface defines fluid nozzle openings that extend from the surface into the print head. Portions of the material pressed onto the surface are therein adhered to the surface and caused to wrap over edges of the surface extending around the openings The transfer film is removed along with a thickness of the material pressed into contact with the surface that remains adhered to the transfer film, as well as some or all of other regions of the material over the openings The remaining layer of the material on the surface is thus formed with a uniform thickness.

    Abstract: An example fluidic device may comprise a fluidic die, a unitary molded structure, and a fluidic fan-out structure—The unitary molded structure may comprise thermo-electric traces and fluidic channels and may be coupled to the fluidic die. A first dimension of the fluidic channels is between ten μm to two hundred μm, or less. The fluidic fan-out structure may also be coupled to the molded structure. The fluidic die, the molded structure, and the fluidic fan-out structure may be arranged such that a first fluidic channel of the fluidic channels is in fluid communication with an aperture of the fluidic die at a first extremity and to a fluidic fan-out fluid channel through hole of the fluidic fan-out structure at a second extremity.

The remaining layer of the material on the surface is thus formed with a uniform thickness.
