A transformable dielectric layer is laser-sintered into measurable circuits, enabling scalable tamper detection across electronic assemblies.

A sealed conductive enclosure uses porous heat transfer elements and pressure sensing to cool secure electronics while detecting tamper events.

Electromagnetic coupling detects device removal from its host component and disables circuitry to block unauthorized reuse and integrity issues.

Different exposed conductor areas use shared base protection and localized gold finishes to prevent corrosion while meeting mixed electrical needs.

A shared non-exposed ENEPIG layer with selective plated gold protects PCB conductor areas, cutting process steps, cost, and corrosion risk.

Integrated tamper circuitry in the heat sink cover and laminate carrier creates a secure volume while improving direct cooling of dense electronics.

Opposed chips overlapping across a PCB route a tamper loop through the board, blocking access to active surfaces and protecting cryptographic material.

Embedded sensor traces and copper thermal paths let a multi-chip security module lid detect tampering while dissipating heat in a compact package.

Additively deposited pyrotechnic layers trigger controlled exothermic fracture of a substrate to block tampering with lower cost and complexity.

Pre-weakened fracture zones and a thermally coupled heater enable controlled self-destruction with lower fracture energy for secure electronics.
