The high purity double sided conductive adhesive carbon tabs and tapes are especially developed for SEM / EDS applications. The material used for both 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 150µm 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; 150µm 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 (2×45µm) combined with high tack
– Long shelf life and can be stored in a refrigerator
– Resistance 50K-200K
High purity conductive double sided adhesive carbon tapes: The material is identical to the material used for the 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 in 5mm, 8mm, 12mm and 20mm width by 20m long.
To use: Cut the required length of carbon tape from the roll and cut to shape if needed (care since one side has exposed adhesive). Adhere tape to the sample support. Remove the top liner and adhere sample to the tape. The use of sharp pointed tweezers helps to lift the liner of the adhesive. The carbon tape can be removed with isopropanol, ethyl acetate, ethanol or acetone.
