PELCO Tabs™ Carbon Conductive Tabs, Double Coated

new types added
The simplicity of application and smooth, clean surfaces of PELCO Tabs™ Carbon Conductive Tabs are a significant improvement compared to many of the other common adhesives that have been used in SEM mounting. Both tab sides have a thick conductive adhesive （conductive inner tab is 35µm and the adhesive is 45µm on each side for a total thickness of 125µm [5 mils]） with a liner on both sides, a transparent liner and white liner respectively. They are ready for immediate use. The top protective liner does not have to be removed until the sample is ready to be mounted. This reduces possible contamination. Outgassing is negligible.

Application of the tab to a mount or surface should be done slowly and carefully to maintain surface smoothness.

The conductive adhesive is a carbon filled acrylic, free of solvents. It can be removed from the specimen mount with ethyl acetate, ethanol, isopropanol, alcohols or our 3M™ Adhesive Remover 80924 which is solvent-free. Temperature maximum is 60°C （140°F）. Small impurities of Si, Sb, S and very small impurities of Fe, Mg and Na can be found.
 

PELCO Image Tabs™, 260µm （10mil） Carbon Conductive Tabs, Double Coated

Back by popular demand, the thicker PELCO Image Tabs™ is a return to the stiff 260µm （10mil） thick smooth conductive tab. Though not as conductive or sticky as the current 10mil PELCO Tabs™, PELCO Image Tabs™ are suitable as a photographic background and are repositionable. This tab is also suitable for Jet Scan applications where the tab must be removed and archived. The PELCO Image Tab’s™ surface is less prone to bubbling and cracking when metal coated under vacuum and thus better than the 125µm （5mil） PELCO Tab™ as a photographic background for small particles like pollen and insect parts.

Both sides of the 200µm thick conductive polycarbonate base have 30µm thick conductive adhesive. Total thickness is 260µm with a liner on both sides. Protection for handling, storage and shipping is provided on one side by the transparent liner sheet and on the other side by the white liner cover.

The conductive adhesive is a carbon-filled acrylic, free of solvents. It can be removed from the specimen mount with ethyl acetate, ethanol, isopropanol, alcohols or our 3M™ Adhesive Remover 80924 which is solvent-free. Temperature maximum is 60°C （140°F）. Small impurities of Ni, Cu, Si, Sb, S, Na, P and very small impurities of Fe and Mg can be found. Refrigeration will increase shelf life but a warm-up time of 1 hour is then required before use.

Conductive Lift-N-Press Adhesive Tabs, Double Sided

Composed of a thin film of strong conductive adhesive approx. 1/2″ （12.7mm） dia.; >99% transparent to EDS, with 0.6% nickel and <0.3% copper content. To apply, place “Press” portion of tab on SEM mount surface, lift “Lift Off” tab and peel, slightly rotating tab when lifting. Can be cut to size as desired.
 

Carbon Conductive Tapes, Double Coated

These carbon tapes are conductive and may be used conveniently for scanning electron microscopy or EDS applications.
This is the same material as the PELCO Tabs™, Carbon Conductive Tabs （top of page）, but in tape form. The tape form allows for special application uses such as custom sizes, cut-outs and shapes. The purity of this tape is identical to the standard tab form at top of page.

3M™ Copper Conductive Tapes
Single Adhesive Surface

The tape is easily cut to size and may be quickly applied to a specimen mount or other surface. Carbon or metallic coating normally is applied to the sample and mount. An electrical discharge bridge is then completed from sample, through the copper and its conductive glue to the grounded specimen mount.
The tape is dead soft copper with a conductive acrylic adhesive. It is supplied on a removable liner for easy handling and cutting. The tape offers excellent conductivity through the foil backing.
This tape is 6.3mm W x 16.46m L （1/4″ x 18 yd） or 12.7mm W x 16.46m L （1/2″ x 18 yd） and the core diameter is 76mm （3″）.

Foil Thickness: 0.04mm （.0016″）
Total Thickness: 0.07mm （.0028″）
Resistance through Adhesive: 0.005 ohm

Technical Note, 16072 （PDF 63KB）

3M™ Copper Conductive Tape, Double Coated

This tape retains the features of the #16072, while enabling the investigator to attach objects directly to the top surface of the tape. The adhesive is conductive. The tape is useful, for example, in attaching insects for SEM investigation. Dimensions are 12.7mm W x 16.4m L （1/2″ x 18 yd）. Core diameter is 76mm （3″）.
Foil thickness: 0.04mm （0.0016″）
Total thickness: 0.09mm （0.0035’）
Resistance through adhesive: 0.010 ohm
