3M 7010045078 Circuit Plating Tape 1280 Red 0.5x72yd 4.2 Mil

Product Description

The 3M 7010045078 is a red polyester film masking tape engineered for printed circuit board electroplating applications. The tape features a 4.2 mil (0.11 mm) polyester film backing combined with a silicone and rubber blend adhesive, providing reliable adhesion and clean removal during the plating process. It is supplied in a 0.5-inch-wide by 72-yard roll, making it well suited for precision masking of narrow traces, contacts, and board sections that must be protected from plating chemistry. Electronics assembly technicians and PCB fabrication specialists are the primary installers and users of this product.

This tape is used in the printed circuit board manufacturing and rework environment, specifically during electroplating operations where selective areas of a board must be masked to prevent metal deposition. Its red color aids visual inspection and alignment during the masking process. The narrow 0.5-inch width allows for precise application along board edges, connector pads, and other tight geometries common in PCB fabrication and repair workflows.

Key Features

• 4.2 mil polyester film backing resists plating chemistry and maintains dimensional stability under process conditions
• Silicone and rubber blend adhesive provides secure hold during electroplating without leaving residue on board surfaces
• Red color aids visual identification and inspection of masked areas
• 0.5-inch width suits narrow masking applications on PCB traces and contact pads
• 72-yard roll length supports high-volume masking tasks with minimal roll changes

Compatibility

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

Installation Notes

Application is performed by electronics assembly technicians or PCB fabrication professionals. Ensure the board surface is clean and dry before applying tape to achieve proper adhesion and a clean mask edge. Apply firm, even pressure along the tape length to prevent plating solution from wicking under the edges. Remove the tape carefully after the plating process is complete, following the board manufacturer's handling guidelines to avoid damage to finished surfaces.
