A tamper-proof cap adapted to be mounted on a large assembly for shielding a selected area of the large assembly is disclosed. The tamper-proof cap comprises a laminate stack-up structure wherein at least one open chamber is formed. The stack-up structure comprises at least two layers wherein tamper-proof layers are formed on top of the open chamber. A plurality of vias are disposed around the open chamber, forming with said tamper proof layers a tamper-proof structure around said open chamber. The vias are adapted for connecting the tamper-proof layers to the large assembly when the tamper-proof cap is mounted. In a preferred embodiment, the tamper-proof cap further comprises a shielding layer on top of the tamper-proof layer that are preferably done using conductive ink. |
