Provided are methods for heat curing of various materials, such as heat curable materials or more specifically potting compounds, which are disposed within cavities with limited access to these materials. Also provided are curing for executing such methods. In some embodiments, a heat curable material disposed within a cavity may be heated by a heating rod protruding into the cavity or through the cavity. The heating rod is thermally coupled to the heat curable material and is used to transfer heat to the heat curable material. For example, the heating rod may include a resistive heating element. The heating element may be positioned in such a way that the heat curable material is selectively heated within the cavity without significant heating of surrounding components. In some embodiments, the heating rod may be also used to compress the part containing the cavity or a stack including this part.

A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.
