High purity conductive double sided adhesive carbon tabs and tapes

ideal for SEM/EDS sample preparation and analysis of powdered samples

Introduction - material - construction

The high purity double sided conductive adhesive carbon tabs and tapes are especially developed for SEM / EDS applications. The material used for bot the tabs and tapes is fully transparent for EDS with only trace amounts of Al and Si. The material is constructed using a non-woven liner coated on both sides with a conductive, carbon filled pressure sensitive acrylic adhesive. Total thickness of the material is approximately 125µm with an adhesive thickness of 45µm on both sides. The adhesive used has a high adhesion strength to metals, plastics,  ceramics, wafers, rubber, wood, glass, paper, and small particles or fibers. The conductivity of the carbon tapes and tabs is lower than the conductivity of double sided copper tape or the double sided conductive Lift-N-Press tabs, but it is still fully compatible with SEM/EDS applications.

Features and benefits of the double sided carbon tabs and tapes are:

• Thin material; 125µm total with 45µm on each side of a 35µm non-woven carrier
• Plastic liner on both sides
• Use temperature range -20°C to + 60°C
• Low outgassing rates
• Fully EDS transparent high purity for EDS applications
• High strength thin adhesive (2x45µm) combined with high tack
• Long shelf life and can be stored in a refrigerator
• Resistance 50K-200K

High purity conductive double sided adhesive carbon tabs

High purity conductive double sided adhesive carbon tabs are supplied on a clear plastic sheet with a white plastic liner tab. Available as Ø12mm and Ø25mm carbon tabs.

To use: lift the tab of 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.

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

High purity conductive double sided adhesive carbon tapes

High purity conductive double sided adhesive carbon tapes: The material is identical to the material used for the tabs with one difference; the tapes include a thin white liner on both sides of the tape. The tape can be shaped into custom forms, strips and cut-outs. Available with 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 form 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.
