Application Guidelines
1.) Substrate surfaces should be clean and dry prior to tape application. Isopropyl alcohol (isopropanol) applied with a lint-
2.) Apply the tape to one substrate at a modest angle with the use of a squeegee, rubber roller or finger pressure to help
3) Assemble the part by applying compression to the substrates to ensure a good wetting of the substrate surfaces with the

5.) Application Tips:
free wipe or swab should be adequate for removing surface contamination such as dust or finger prints. Do not use
“denatured alcohol” or glass cleaners, which often contain oily components. Allow the surface to dry for several
minutes before applying the tape. More aggressive solvents (such as acetone, methyl ethyl ketone [MEK] or toluene)
may be required to remove heavier contamination (grease, machine oils, solder flux, etc.) but should be followed by a
final isopropanol wipe as described above.
Note: Be sure to read and follow the manufacturers’ precautions and directions when using primers and solvents.
reduce the potential for air entrapment under the tape during its application. The liner can be removed after positioning
the tape onto the first substrate.
tape. Proper application of pressure (amount of pressure, time applied, temperature applied) will depend upon design of
the parts. Rigid substrates are more difficult to bond without air entrapment as most rigid parts are not flat. Use of a
thicker tape may result in increased wetting of rigid substrates. Flexible substrates can be bonded to rigid or flexible
parts with much less concern about air entrapment because one of the flexible substrate can conform to the other
substrates.
• For rigid to rigid bonding, a twisting motion during assembly of the substrates will improve wetting. This should be a
• For flexible to rigid or flexible to flexible bonding, a roll lamination system may be employed to apply the flexible
• Heat can be employed to increase wetting percentage and wetting rate of the substrates and to build room temperature
• Primers may be employed to increase adhesion to low surface energy substrates (eg. plastic packages). Contact your
• For best product performance, it is important to use pressure and time conditions to achieve as much wetting as possible.
