Method and curable compound for casting electronic components or component groups

A method for casting electronic components or component groups, in which the component or the component group is embedded in a casting compound which is cured via at least one cross-linking process, wherein:

• a casting compound is used which contains at least one cross-linking component A, which is homogeneously distributed in the casting compound and can cross-link to form at least two different cross-linked systems, of which a first system is formed by the at least one cross-linking component A alone,
• an at least partial cross-linking to form the first system is triggered by a first event in at least a first region of the casting compound,
• the casting compound contains at least one second component B, which is homogeneously distributed in the casting compound and with which the at least one cross-linking component A can form a second of the at least two different systems, which has a lower cross-link density than the first system,
• the cross-linking to form the second system can be triggered by a second event in at least one second region of the casting compound, in which the first system has not been formed or has only been partially formed,
• the casting compound contains at least one third component C, which is homogeneously distributed in the casting compound and, after the at least partial cross-linking to form the first system, reacts with not yet cross-linked components of the at least one second component B in the first region and the second region to form a further system,
• a reaction of the third component C with the second component B is triggered by the second event,
• the at least one cross-linking component A of the casting compound is at least partially cured to form the first system in at least one region kept at a distance from a first electronic component or an electronic component group, and is cured to form the second system at least in a region enclosing and directly surrounding the electronic component or the electronic component group, as a second region.
