摘要：The invention relates to a tamper relates to a tamper resistant modules for aprinted circuit board. In the drawing, only one of the tamperproof modules (2) is
illustrated for mounting on a PIN pad which is not shown. There is illustrated a PCB board(10) upon which is mounted a protection layer (16) which comprises an insulation layer(17) and another layer carrying serpentine tracks which are connected to a detectioncircuit on the PCB (10). Against the layer carrying the serpentine tracks, there is a furtherinsulation layer (22) and above which there is a final layer of crossing earthed tracks. Aconductive edge protection track (not shown) is also provided on the PCB (10). Anyattempt to drill through the protective layers (15) will lead to a fault condition beingsignalled which can, in certain instances, cause the RAM on the PCB to be deleted.
