Printed circuit boards (PCB) are used in a number of electronic systems, including Global Positioning System devices. Some PCBs contain important information that can compromise a company's files and business operations if the information is obtained illegally. To prevent illegal tampering, a company protects its PCB by enclosing it with a metal enclosure with Gore mesh lining. If this lining becomes damaged, it can tell the company that someone had tampered with the PCB.
Instructions
1 Lay the metal shielding on the table with the inside facing upward. Wipe any dust from the metal with a clean cloth.
2 Place epoxy to the center of the metal shielding. Lay the Gore mesh flat against the metal shielding. Allow the epoxy to dry.
3 Secure the mesh and shield to the PCB with connectors linked to security detectors. Tighten the screws on the connector through the mesh and along the edges of the PCB. The connectors sense when the mesh is being tampered with and send a signal to the security detectors. The security detectors pick up the signal to erase the encryption keys and memory on the PCB to stop the theft of information.
