Copper tapes

EM-Tec premium, single-sided, conductive copper SEM tapes

EM-Tec premium, single-sided, conductive copper tapes are indispensable for making ground contacts between the specimen surface and SEM stub or SEM specimen holder. The tape is made from soft copper foil which is easily moulded to follow the shape of the specimen. EM-Tec premium copper SEM tapes are highly electrically conductive with a conductive pressure sensitive acrylic adhesive and a paper liner. The resistance of the applied tape is < 1 Ohm with a high initial tack to provide good adhesion. It is recommended to apply light pressure on the tape to improve conductivity.

Available in widths of 3, 6, 10,12, 20 and 25mm with a length of 25m. The conductive adhesive side is covered with siliconised backing paper liner and comes on a clean 76mm diameter plastic core.

EM-Tec double-sided conductive copper tape for SEM / FIB applications

EM-Tec double-sided conductive copper tape has a layer of conductive acrylic adhesive on both sides. Highly electrically conductive with a resistance through the adhesive <1 Ohm. This double-sided conductive copper tape has the same specifications as 3M 1182 tape. It is deal for mounting specimens directly onto SEM stubs whilst establishing a grounding path. It can be used either to mount large specimens onto SEMs stubs or for smaller specimens directly onto the tape. Non-conductive specimen surfaces should be coated to obtain best imaging results. The tape is suitable for long term applications. Copper tape has much better conductivity
