SPC8513-1XCU
(Bondable
Copper Sheet)
|
24-inch copper rolls with conductive pressure sensitive that can be die-cut and applied onto plastic and large area enclosure as "sheet-coating " to provide more than 60dB shielding effectiveness. It conforms to most common curvatures without spray-coating problems. The exposed surface is insulating to prevent bridging with devices. |
