3M™ Circuit Plating Tape 1279 is a polyester film tape with specially formulated adhesive for masking many printed wiring boards during the gold tip plating process.

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 to reduce stretch and recovery of tape and associated uneven stop-off line.
  • Thick adhesive coating which reduces undercutting because adhesive helps block out solutions between fingers.
  • Specially designed adhesive which generally performs better when no heat is used to apply tape and reduces adhesive transfer to printed wiring boards.

APPLICATIONS

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