Technical Data | August 2017 TM 3M™ High Shear Pressure Sensitive Cover Tape 2668 Product description 3M™ High Shear Pressure Sensitive Cover Tape 2668 is a transparent, conductive polyester lm tape with a synthetic, room temperature, pressure sensitive adhesive (PSA) zone along each edge. 3M cover tape 2668 is designed to seal electrical and electronic components into 3M's family of polycarbonate carriers. It also works well with certain other embossed carrier tapes. Construction Backing Adhesive Inner face Transparent polyester lm Pressure-sensitive, synthetic polymer Transparent, conductive, polyester film Available widths 3M cover tape 2668 is available in the standard sizes listed below, with adhesive exposed only along the edges. All 3M cover tape 2668 is supplied in 300 meter, splice-free rolls.

Standard packaging format 3M cover tape 2668 is provided on a plastic core, packaged with high density paper wafer inserts and a centering core in a single polyethylene bag and is placed between two end-caps with corrugated pads in a cardboard carton. Initial adhesion and aging data 3M cover tape 2668 has a simple process window. Desirable initial peel force values can be achieved with the application of adequate pressure to the non-adhesive surface of the cover tape over the adhesive stripes with a reciprocating shoe, or compliant roller mechanism. The charts on the following page depict the typical room temperature and aging characteristics of 3M cover tape 2668 after sealing to 3M™ Polycarbonate Carrier 3000 and 3M™ Clear Polycarbonate Carrier 2703. 3M™ High Shear Pressure Sensitive Cover Tape 2668 Typical removal force results Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. 3MTM Cover Tape 2668 on 3M TM Polycarbonate Carrier 3000 Room temperature 3M TM Cover Tape 2668 on 3M TM Polycarbonate Carrier 3000 o o 52 C ( 125 F)/95% RH Average peel force (grams) Average peel force (grams) 100 80 60 40 20 0 0 1 3 7 15 20 100 80 60 40 20 0 30 0 1 3 Days 7 15 20 30 Days Sealing parameters Cover tape: Carrier tape: Sealing mode: Pressure: Speed/ Dwell time: Temperature: 3MTM Cover Tape 2668 on 3M TM Clear Polycarbonate Carrier 2703 Room temperature 100 Averagepeel force (grams) Average peel force (grams) 100 3MTM Pressure Sensitive Cover Tape 2668, 5.4 mm 3MTM Polycarbonate Carrier 3000, 8 mm Reciprocating 1.0 bar 100 ms Room temperature ≈ 23°C (73°F) 80 60 40 20 0 80 60 40 20 0 0 1 3 7 15 20 3M TM Cover Tape 2668 on 3M TM Clear Polycarbonate Carrier 2703 o o 52 C ( 125 F)/95% RH 30 0 1 3 7 15 20 30 Days Days Sealing Parameters Cover tape: Carrier tape: Sealing mode: Pressure: Pressure: Speed/ Dwell time: Temperature: 3M cover tape 2668, 5.4 mm 3MTM Clear Polycarbonate Carrier 2703, 8 mm Reciprocating 1.0 bar 1.0 bar 100 ms Room temperature ≈ 23°C (73°F) Graph notes Notes: The graphs in this document represent sealing performance attained under the conditions specifically stated in the sealing parameters section of the charts. Pressure is the indicated gauge pressure used to achieve the seals, and may vary among sealing equipment manufacturers. The use of a different sealing mechanism, i.e., reciprocating vs. roller, may have an effect upon the performance obtained under otherwise identical conditions due to differences in pressure or pressure distribution. The use of heat is specifically not recommended. All data presented are representative of peeling studies conducted according to the requirements of the current ANSI/EIA481-E Standard. Sealed samples used in these studies were stored under the conditions noted, wound on 180 mm diameter reels to simulate typical production use. Samples being tested at elevated temperature and humidity were permitted a minimum equilibration period of four hours at room temperature prior to testing to simulate actual use conditions.

The application of heat to seal PSA cover tapes is specifically not recommended. Pressure in the range of 10 to 50 psig is sufficient to seal PSA adhesives. 2. Tensile tests and thickness measurement are conducted at 21°C (70°F), 70% RH, in the machine direction of the polyester f ilm. 3. Optical properties are measured using the BYK-Gardner Haze-Gard Plus Transmission Meter. 4. 0.5” x 0.5” adhesive secured to polycarbonate substrate with 1,000 gm load. 5. Resistivity is measured at room temperature by resistance meter. Measurement technique: 4-bar probe with Keithley 237 Source Measuring Unit. Typical adhesive properties The synthetic adhesive used in the construction of 3M™ High Sheer Pressure Sensitive Cover Tape 2668 has been engineered to provide long term resistance to thermal degradation, even when exposed to environmental extremes such as the storage conditions depicted in the charts in this publication. Storage conditions and shelf life 3M cover tape 2668 should be stored indoors, in its original packaging, in a controlled climate environment ranging 22°C - 28°C (72°F - 82°F) and not exceeding 70% relative humidity. The product should be protected from direct sunlight and should be used on a "first-in, first-out" basis. The shelf life of 3M cover tape 2668 is two years from the date of manufacture when stored according to the recommended storage conditions.
