Super smooth conductive double sided carbon tapes and tabs

Micro to Nano super smooth high purity double sided conductive adhesive carbon tapes and  tabs (also known as carbon discs and sticky tabs)  are especially developed for imaging and analysis applications of fine powders and fibre samples. The adhesive material used for the tabs and tapes is fully transparent for EDS analysis with only trace amounts of Al and Si. The material is constructed using a super smooth aluminium foil coated on both sides with a conductive, carbon filled, pressure sensitive, acrylic adhesive. The result is a super smooth surface combined with high conductivity. Total thickness of the material is approximately 110µm with an adhesive thickness of 40µm on each side. The adhesive exhibits a high adhesion strength to metals, plastics, ceramics, wafers, rubber, wood, glass, paper, and small particles or fibres.

 

Micro to Nano super smooth double sided carbon tabs and tapes are:

  • Super smooth thin material: 110µm total with 40µm adhesive on each side of the aluminium foil carrier
  • High conductivity
  • Excellent for fine powders and small fibres
  • Ideal for automated EDS particle analysis
  • Use temperature range -20°C to + 60°C
  • Low outgassing rates
  • Fully EDS transparent high purity for EDS applications
  • High strength thin adhesive (2 x 40µm) combined with high tack
  • Long shelf life and can be stored in a refrigerator

Super smooth conductive double sided adhesive carbon tabs

EM-Tec super smooth conductive double sided adhesive carbon tabs are supplied on a clear plastic sheet with a white plastic liner tab. Available as Ø12mm and Ø24mm carbon tabs.

To use: lift the tab off the clear backing sheet, press the sticky surface to the mount, then peel away the white liner tab, leaving the adhesive exposed. Mount sample on the exposed adhesive. Alternatively, the white liner tab can be removed, the stub pressed on the exposed carbon tab and the clear plastic lifted off.  The use of sharp pointed tweezers helps to lift of the tabs and liner. The carbon tabs can be easily removed with isopropanol, ethyl acetate, ethanol or acetone.

  • Ø12mm carbon tabs are compatible with Ø12.7mm pin stubs, Ø12.2mm JEOL stubs and Ø15mm Hitachi stubs.
  • Ø24mm carbon tabs are compatible with Ø25.4mm pin stubs, Ø25mm JEOL stubs and Ø25mm Hitachi stubs.

Super smooth conductive double sided adhesives carbon tapes

Super smooth conductive double sided adhesive carbon tapes: The material is identical to the material used for the super smooth carbon tabs with one difference; the tapes are self-wound with a thin white liner on one side of the tape. The tape can be shaped into custom forms, strips and cut-outs. Available with 5mm,  8mm, 12mm and 20mm width by 20m long.

To use: Cut the required length of carbon tape. Cut to shape if needed. Remove the white liner from one side and adhere to tape to the sample support. The use of sharp pointed tweezers helps to lift the liner of the adhesive. Remove the top liner and adhere sample to the tape. The carbon tape can be removed with isopropanol, ethyl acetate, ethanol or acetone.

If smoothness of the surface is not a requirement, the lower cost high purity carbon tapes are an excellent alternative.
