Abstract
A security enclosure and method of forming the security enclosure. The security enclosure includes an electronic assembly, an extension, and a tamper respondent wrap. The extension has a first end inserted in the assembly and a second end having at least one bonding pad thereon. The tamper respondent wrap at least partially surrounds the assembly. The wrap has a bonding pad. The bonding pad of the extension is secured to the bonding pad of the wrap. The tamper respondent wrap includes a plurality of layers. A plurality of electrically conductive lines or a plurality of electrically conductive ink traces exist within each layer of the wrap.
Claims12
A method of forming a security enclosure, comprising:
- providing an electronic assembly;
- providing an extension having a first end inserted in the assembly and a second end having at least one bonding pad thereon;
- and providing a tamper respondent wrap at least partially surrounding the assembly, the wrap having a bonding pad, wherein the bonding pad of the extension is secured to the bonding pad of the wrap, wherein the tamper respondent wrap comprises a plurality of layers, wherein a plurality of electrically conductive lines or a plurality of electrically conductive ink traces exist within each layer of the wrap;
- wherein a first layer and a second layer of the plurality of layers each comprise a first conductive ink trace, a second conductive ink trace, and a third conductive ink trace which are oriented parallel to one another and each further comprise a fourth conductive ink trace that is mechanically and electrically connected to both the first conductive ink trace and the third conductive ink trace, and wherein the first conductive ink trace, the second conductive ink trace, and the third conductive ink trace are each in direct mechanical and electrical contact with a respective first bonding pad, second bonding pad, and third bonding pad.
