3M 7000123309 Circuit Plating Tape 1280 Red 0.5in X 144yd

Product Description

The 3M 7000123309 is a red polyester film circuit plating tape designed for precision masking of printed circuit boards during electroplating operations. Built on a 4.2 mil (0.11 mm) polyester film backing with a silicone and rubber blend adhesive, this tape delivers clean edge definition and reliable adhesion through the plating process. The roll measures 0.5 inches wide by 144 yards long, making it well-suited for production-volume masking runs. Electronics technicians and PCB assembly professionals apply this tape where accurate, repeatable masking is required to protect board areas from plating chemistry.

This tape is used in printed circuit board manufacturing and rework environments where selective electroplating is performed. The red color provides clear visual contrast against board substrates, supporting quick inspection before and after processing. It is appropriate for both prototype shops and higher-volume production lines where consistent masking performance across long tape runs is a requirement. Facilities handling through-hole and surface-mount board plating are the primary application setting.

Key Features

• 4.2 mil polyester film backing resists plating chemistry and maintains dimensional stability during processing
• Silicone and rubber blend adhesive provides secure hold with clean removal after plating
• Red color offers high visual contrast for easy inspection and alignment on PCB substrates
• 0.5 inch width suited for narrow masking lanes and trace-level coverage
• 144-yard roll length supports extended production runs and reduces changeover frequency

Compatibility

Designed as an OEM-style masking solution for printed circuit board electroplating operations where a thin, chemically resistant polyester film tape is required.

Installation Notes

Application is typically performed by electronics assembly technicians or PCB fabricators working in a controlled production environment. Ensure the board surface is clean and free of oils or residue before applying the tape to achieve full adhesive contact. Apply firm, even pressure along the tape edge to prevent plating chemistry from undercutting the mask. Remove the tape promptly after plating in accordance with the process specification to avoid adhesive transfer.
