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.
