PELCO Tabs™ Carbon Conductive Tabs, Double Coated

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). High purity carbon tabs may contain very small impurities of Al and Si; see EDX Spectra.
This product may also be used for gunshot residue analysis.
Many laboratories use these tabs for SEM in a large diversity of applications. Refrigeration will increase shelf life but a warm up period of one hour is then required before use.
The PELCO Tabs™ consist of a carbon fiber mat impregnated with carbon filled acrylic adhesive. There is no internal carrier film.

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.

carbon conductive tape

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, 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 PELCO Tabs™; only very small impurities of Al and Si may be found.

Both sides of the tape have a thick conductive adhesive (conductive inner film is 35µm and the adhesive is 45µm on each side for a total of 125µm [5 mils]) with a white liner. The double adhesive and conductive design permits quick mounting of samples without using liquid or colloidal adhesives.
The tape is relatively solid and non-porous and does not absorb small samples. The variety of widths affords efficient application to various specimen mount surface sizes. Thickness is 0.16mm. Available in four widths. Can be used down to -20°C (-4°F) and temperature maximum is 60°C (140°F). Available in 8, 12, 20, 25, and 50mm W x 20m L (.31, .47, .79, .98, and 1.96" x 21.8 yd).

3m XYZ Electrically Conductive Double Sided Tape
magnified view of fibers

3M™ XYZ Axis Tape, Electrically Conductive, Double Sided, 9712 and 9713

This highly conductive double sided tape with excellent adhesion and conductivity properties has been initially developed for bonding EMI/RF shields.  Advantages of this new tape are:
  • Improved adhesion - creates a solid bond and allows attachment of dissimilar materials
  • Easy handling - more solid tape, conductive fibers reinforced and easier to remove
  • High conductivity - creates solid electrical connections

Due to the high electrical conductivity and excellent bonding properties these tapes are ideally suited for bonding conductive samples on SEM specimen mounts or directly on SEM specimen holders. They can be used under clean room conditions. The conductive nickel fibers extend above the adhesive ensuring a solid electrical connection between parts. It is less suitable for mounting small or powder like specimen due to the fibers in the adhesive and the topographic surface. Type 9713 has less resistance than Type 9712, see chart below:

Based upon four wire (Kelvin probe) resistance measurements made with crossed pieces of Foil/Type 9712 or 9713/Rigid plate construction using a 1.0" x 1.0" square piece of 3M tape Type 9712 or 9713. The rigid metal surface was prepared with a Scotch-Brite™ pad to roughen the surface and cleaned with isopropyl alcohol.

XYZ highly conductive tape comes on a 76mm (3") plastic core and sizes for Type 9712 are 6.35mm, 12.7mm and 25mm W x 32.9m L (1/4", 1/2" and 1" x 36 yd) and for Type 9713 is 12.7mm, 25mm, and 100mm W x 32.9m L (1/2", 1", and 4" x 36 yd), .61m W x 98.6m L (24" x 108 yd), .61m W x 32.9m L (24" x 36 yd).

Thickness: 0.127mm (5 mil). The tape adhesive can be removed relatively easily by pulling off, rubbing or by application of packaging tape over the residual adhesive. Adhesive can be dissolved in acetone.
