Features

• Low stretch polyester film for machine, as well as hand application.

• Solvent clean up of the board is recommended to facilitate subsequent soldering.

• Polyester backing reduces stretch and recovery of tape and associated uneven
stop-off line.

• Thick adhesive coating reduces undercutting because adhesive helps block out
solutions between fingers.

Typical Physical
Properties

Note: The following technical information and data should be considered representative

or typical only and should not be used for specification purposes.

Application Ideas

• Masking of many printed wiring boards during solder stripping and precious
metal plating of fingers.

• Splicing of silicone treated papers.

Application Techniques

• Must be firmly pressed down by equipment with rubber-covered rollers. Hand
rolling usually does not provide enough pressure. A vivid outline of the circuit
leads usually indicates that adequate pressure was used.

• Tape generally performs better when no ovens are used to heat tape and boards.
