Bonding and protecting through-hole components in the printed circuit board
assembly operation.

For best results, clean the surface first with mix of isopropyl alcohol
and water (50/50 mix).  Apply the tape by hand.  Note:  Follow the solvent
manufacturer’s precautions and directions for use when handling solvents.

Ability to absorb and damp vibrational energy, and withstands
IR reflow temperatures.

Shock resistant: 3M

VHB

™

Tapes have the ability to absorb energy during

impact which can help protect component leads.

Vibration resistant: The energy absorbing 3M VHB tapes can help prevent
fatigue failure of the solder connection in many high vibration environments.

cleaning: 3M VHB tapes have excellent solvent

resistance and can maintain a bond through harsh conditions of most
Freon cleaning operations.

Resistance to temperature extremes and thermal shock: 3M VHB tapes offer
excellent temperature performance in many demanding applications in
temperature extremes.  3M VHB tapes have passed thermal shock tests of
hourly cycles from -40° C to 150° C for 1000 hours.  These tapes can also
tolerate most IR reflow process conditions.

Compatible with conformal coating: Components bonded in place with 3M
VHB tapes can be conformal coated without adverse degradation of the tape’s
adhesive and physical properties during the process.

Die-cuttable: 3M VHB tapes are easily die-cut to many specific shapes for
ease of handling during the assembly process.
