3M 7000048773 Circuit Plating Tape 1280 Red 12in X 72yd 4.2 Mil

Product Description

The 3M 7000048773 is a red polyester film masking tape engineered for printed circuit board (PCB) electroplating applications. The tape features a 4.2 mil (0.11 mm) polyester film backing combined with a silicone/rubber blend adhesive that holds firmly during plating processes and releases cleanly without leaving residue. At 12 inches wide and 72 yards per roll, this format covers large masking runs efficiently. Electronics manufacturing technicians and PCB fabricators use this tape to protect areas of a circuit board that must be kept free of plating deposits during selective electroplating operations.

Tape 1280 is designed for PCB masking in electroplating lines where precise coverage, clean adhesion, and reliable removal are critical. It performs in the wet chemical environments typical of circuit board plating baths, maintaining adhesion through the process without lifting or allowing plating solution to migrate under the edge. Suitable for use in electronics manufacturing facilities and contract PCB shops handling both prototype and production-volume plating work.

Key Features

• 4.2 mil (0.11 mm) polyester film backing resists chemical exposure in electroplating bath environments
• Silicone/rubber blend adhesive bonds securely to board surfaces and releases cleanly post-plating
• Red color provides clear visual contrast for inspection and alignment during masking
• 12 inches x 72 yard roll format suits high-coverage and production-volume masking tasks
• Sold in minimum quantities of 4 rolls per order (UOM: Roll)

Compatibility

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

Installation Notes

Application is performed by electronics technicians or PCB fabrication personnel. Apply tape to clean, dry board surfaces prior to introducing the board into the plating bath, pressing edges firmly to prevent solution migration. Remove tape promptly after the plating process is complete to minimize any adhesive interaction with the board surface. Handle tape rolls in a clean environment to avoid contamination of the adhesive layer before use.
