ABSTRACT:
A secure electronic circuit on a printed circuit board is disclosed. The electronic circuit is enclosed in a housing comprising two shells located in abutment with opposite faces of the printed circuit board. One shell is provided with a first element that extends through an aperture in the printed circuit board and the other shell is provided with a second element that irreversibly engages with the first element and thereby secures both shells to the circuit board and inhibits removal of either shell. The construction is such that removal of either shell results in irreversible damage to the housing.
