Abstract: A method is described for joining, in particular adhering, plastic to a substrate. To achieve a strong adhesive effect, in a method task a) a plastic material that encompasses at least one thermally reversibly cleavable polymer is furnished, and in a method task b) the plastic material is brought into contact with the substrate, a portion of the plastic material which is brought into contact with the substrate being heated to a temperature at which the at least one thermally reversibly cleavable polymer of the plastic material becomes thermally cleaved, and re-cooling or being re-cooled while in contact with the substrate. Also described is a plastic/substrate composite manufactured thereby, a polymer, and a polymer use for adhering.

Abstract: A method for producing a coil, in particular an ignition coil for a motor vehicle, in which a primary winding is wound onto a winding mandrel. Then the winding mandrel is introduced into a housing of the coil and the winding mandrel then is removed from the housing, the primary winding remaining inside the housing. Finally, additional components of the coil, in particular a secondary coil shell onto which a secondary winding has been wound, are introduced into the housing, so that the secondary winding is concentrically disposed within the primary winding while dispensing with a separate primary coil shell. The method allows a design of the coil that is more compact in diameter.

Abstract: An ignition coil for an internal combustion engine has a core, which is provided with a plastic extrusion coat on its periphery. The core is concentrically surrounded by a secondary coil and a primary coil. The plastic extrusion coat of the core is used as a coil shell for the secondary coil so that it is possible to dispense with a separate secondary coil shell. The ignition coil therefore has an especially compact design.

Abstract: An electronic component, in particular an ignition coil, has an encapsulating compound which is formed by a mixture of an A component containing epoxy resin, a flexibilizator, additives, and fillers, and a B component containing at least one curing agent. The flexibilizator is formed from a material from the group of elastic thermoplastics and elastomers and is embedded in an epoxy matrix. To manufacture such an electronic component, the encapsulating compound is formed by mixing the A component with the B component, which contains at least one curing agent and optionally an accelerator, the A component being previously produced by mixing the epoxy resin with the flexibilizator, the additives, and the filler.
