Abstract
A structure and method for forming a tamper respondent electronic circuit enclosure that includes an integrated circuit structure, a mesh structure surrounding the integrated circuit structure, and a sealed enclosure surrounding the mesh structure. The mesh structure includes a layer of flexible dielectric having a first side and a second side, a screen-printed pattern of flexible electrically conductive first circuit lines forming a first resistor network on the first side, and a photo lithographically-formed pattern of flexible electrically conductive second circuit lines forming a second resistor network on the second side.
