About INT 701 High Temperature Polyimide Masking Tape & Dots

INT 701 polyimide masking tape is a polyimide film with a silicone adhesive designed for temporary masking during soldering and other high temperature processes. This solder masking tape is formulated to be removable leaving no residue.

Polyimide film retains its excellent physical and electrical properties over a wide temperature range. Polyimide film will not burn, will not melt, has no known solvents, and has good radiation resistance. Polyimide film is very often known as “Kapton”, which is a brand name and registered trademark of E.I. du Pont de Nemours and Company, a manufacturer of polyimide materials.

Features & Benefits

  • High temperature resistanceINTD7006
  • No residue
  • Competitive price
  • Wire insulation for extreme environments
  • Also available in die-cut discs


  • Soldering: Masking gold fingers or other sensitive areas during the soldering process. Especially useful where excessive heat is applied (for example: multiple immersions or long preheats during wave soldering) or if tape is to be left on the pcb after processing. Some low-solids fluxes require higher temperature preheats. We recommend INT 701 if this is the case. Temporary fixturing during soldering.
  • Hot air levelling
  • Multi-layer PCB production
  • Hot dip galvanising
  • Plasma spraying
  • Annealing
  • Wire insulation for extreme environments, e.g. aerospace.
