Abstract:
A tamper-protected electronic module comprises a printed circuit board having a first side, on which electronic components of an electronic circuit including at least one microchip are located, and a housing cover that is facing the first side of the printed circuit board. The housing cover has, on the inside thereof, a sealed inner frame that extends to the first side of the printed circuit board and surrounds only a security-relevant portion of the electronic circuit including the microchip. The volume enclosed by the inner frame between the first side of the printed circuit board and the housing cover is filled with a casting resin under formation of a coherent casting compound.
