3M™ Cleanroom High Temperature ESD Tape 1258 is a translucent, polyimide film tape with silicone adhesive with unique and extremely low electrostatic discharge properties. For gold tab protection during wave soldering of printed circuit boards.

FEATURES

  • Product is packaged in cleanroom.
  • Rolls are wound onto plastic cores and bagged with Class 100 clean film.
  • 3M tape 1258 employs a proprietary technology that results in extremely low electrostatic discharge at unwind and removal from the PWB. 
  • At room temperature the properties of polyimide and polyester film are similar. However, as the temperature increases or decreases, the properties of the polyimide film are less affected than polyester.
  • Polyimide film does not soften at elevated temperatures; thus, the film provides an excellent release surface at elevated temperatures.

APPLICATIONS

  • Mask for printed circuit boards during wave solder or solder dip process.
  • Used as release surface in fabrication of parts cured at elevated temperatures.
