3M™ Circuit Plating Tape 1278

3M™ Circuit Plating Tape 1278 is a polyester film tape with a specially formulated silicone-free adhesive for masking solder mask over bare copper (SMOBC) printed wiring boards during the gold tip plating process.

FEATURES

• Silicone-free adhesive which eliminates silicone removal.
• Low stretch polyester film for machine, as well as hand application.
• Solvent clean up of the board is recommended to facilitate subsequent soldering.
• High strength, stable polyester backing which provides even stop-off line.
• 2 mil adhesive coating thickness which is thick enough to help prevent leaking on a wide range of solder mask surfaces and thin enough for easy handling and removal from board.
• High strength adhesive which virtually eliminates adhesive transfer after tape removal.

APPLICATIONS

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