3M 7010045121 Circuit Plating Tape 1280 Red 3in X 144yd

Product Description

The 3M 7010045121 is a red polyester film tape engineered for printed circuit board masking during electroplating operations. Sold as Tape 1280, it features a 4.2 mil total thickness and uses a silicone/rubber blend adhesive that holds securely through plating baths while releasing cleanly without leaving residue on sensitive board surfaces. Each roll measures 3 inches wide by 144 yards long, providing substantial coverage for production-volume masking work. Electronics assemblers, PCB fabricators, and contract manufacturers rely on this tape to protect board areas from plating chemistry during gold, tin, or other electroplating processes.

This tape is suited for use in printed circuit board production environments where precise masking is required during selective electroplating. The red color provides clear visual identification of masked zones on the board, reducing mismasking errors in production workflows. Its polyester film backing resists the mechanical and chemical stress typical of plating bath exposure, making it appropriate for both prototype runs and higher-volume fabrication lines. It is applied by hand or with tape dispensing equipment and is removed after the plating cycle is complete.

Key Features

• Red polyester film backing for clear visual masking identification on circuit boards
• 4.2 mil total thickness for dimensional stability during plating operations
• Silicone/rubber blend adhesive bonds securely and releases cleanly post-plating
• 3 inches wide by 144 yards per roll supports production-volume applications
• Designed to resist plating bath chemistry without backing deformation

Compatibility

Designed as an OEM-style masking solution for printed circuit board electroplating applications where a polyester film tape with chemical-resistant adhesive is required.

Installation Notes

Application and removal should be performed by trained electronics assembly or PCB fabrication technicians familiar with selective plating masking processes. Ensure board surfaces are clean and free of oils or contaminants before applying tape to achieve proper adhesion and edge seal. Remove the tape promptly after the plating cycle per the process specification to facilitate clean release. Follow all facility chemical handling and safety protocols when working in electroplating environments.
