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.
ASTM Test Method
Adhesion to Steel:

31 oz./in. width (33.9 N/100 mm)

D-3330Tensile Strength at Break:

30 lbs./in. width (525.4 N/100 mm)

D-3759Elongation at Break:135%

D-3759Backing Thickness:

0.9 mils (0.020 mm)

D-3652

Total Tape Thickness:

3.6 mils (0.091 mm)

D-3652Features• 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.

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 enoughpressure. 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.
