  • Patent number: 10861762
    Abstract: The present disclosure relates to an explosion resistant electronic module having a high-speed interface and a method for electronic contacting of such electronic module via such interface. The electronic module includes an electronic component, an electrical contact area for electrical contacting the electronic component and an encapsulation, which encapsulates at least the electrical contact area. The encapsulation is embodied such that the contact area is contactable through the encapsulation by an electrical contact pin, wherein the encapsulation is filled at least in a portion with a self-healing gelatinous potting compound, which enables the encapsulation to be re-sealed after removal of the contact pin.
