3M 7010045146 Circuit Plating Tape 1280 Red 3in X 72yd

Product Description

The 3M 7010045146 is a red polyester film masking tape rated at 4.2 mil (0.11 mm) total thickness, designed for printed circuit board masking during electroplating operations. The tape combines a polyester film backing with a silicone and rubber blend adhesive that holds firmly during plating baths while releasing cleanly without leaving residue on board surfaces. Electronics assembly technicians and PCB fabricators use this tape to protect specific areas of a board from plating chemistry, ensuring precise deposit boundaries and maintaining dimensional accuracy on finished assemblies.

This tape is suited for production and rework environments where controlled plating coverage is required on printed circuit boards. The red backing provides clear visual confirmation of masked zones under production lighting, reducing misapplication errors during high-volume runs. It is sold by the roll and typically purchased in case quantities by PCB fabricators, electronics contract manufacturers, and MRO supply rooms supporting electronics production lines.

Key Features

• 4.2 mil total thickness polyester film construction resists tearing during application and removal
• Silicone and rubber blend adhesive provides secure hold through electroplating bath exposure
• Red backing allows quick visual identification of masked circuit board areas
• 3 inches wide by 72 yards per roll suits both detailed masking work and longer continuous runs
• Clean removal helps protect circuit board surfaces from adhesive residue after plating

Compatibility

Designed as an OEM-style replacement masking tape for printed circuit board electroplating applications where a polyester film tape with solvent-resistant adhesive is specified.

Installation Notes

Application is performed by PCB fabricators and electronics assembly technicians as part of the pre-plating masking process. Ensure board surfaces are clean and dry before applying tape to maximize adhesive contact and seal integrity at mask edges. Remove the tape promptly after plating is complete and the board has returned to ambient temperature to minimize adhesive residue risk. Follow applicable facility safety procedures when handling electroplating chemistries.
