Abstract: PROBLEM TO BE SOLVED: To provide a structure and a method of forming a fraudulent intrusion sensing electronic circuit enclosure including an integrated circuit structure, a mesh structure surrounding the integrated circuit, and a sealing enclosure surrounding the mesh structure. SOLUTION: The mesh structure includes a flexible dielectric layer having a first side and a second side, a screen print pattern of a first flexible conductive circuit line forming a first resistor network on the first side, and a photolithography forming pattern of a second flexible conductive circuit line forming a second resistor network on the second side.
