3M 7000001274 Pcb Tape 851 Green 46in X 36yd 4.0 Mil

Product Description

The 3M 7000001274 is a Greenback Printed Circuit Board Tape designed for masking applications in PCB plating processes. It features a 1 mil polyester film backing with a heavy coat weight silicone and rubber blended adhesive that delivers excellent conformability around board edges and component features. Total tape thickness is 3.6 mil. The translucent green color allows technicians to visually confirm coverage during masking. This roll measures 46 inches wide by 36 yards long, making it well suited for high-volume or wide-format PCB masking operations. Electronics assembly technicians and PCB fabrication professionals are the primary installers of this product.

This tape is intended for use in printed circuit board plating and masking processes, particularly where conformability and clean adhesive removal are critical. The wide 46-inch format accommodates large panel or batch masking setups common in commercial PCB fabrication environments. It performs in the chemical and thermal exposure conditions typical of electroplating and related PCB surface finishing operations.

Key Features

• 1 mil polyester film backing for dimensional stability during plating processes
• Heavy coat weight silicone and rubber blended adhesive for strong, conformable masking
• 3.6 mil total tape thickness for reliable edge sealing
• Translucent green color for easy visual inspection of masked areas
• 46-inch width supports wide-panel and batch PCB masking applications
• 36-yard roll length minimizes changeover frequency in production settings

Compatibility

Designed as an OEM-style masking tape for use in printed circuit board plating and surface finishing processes where polyester-backed, silicone-adhesive tape is specified.

Installation Notes

Application should be performed by trained PCB fabrication or electronics assembly technicians following established ESD and cleanroom protocols where applicable. Ensure board surfaces are clean and free of contamination before applying tape to achieve proper adhesion and plating isolation. Remove tape promptly after the plating process is complete to reduce the risk of adhesive transfer. Handle the wide-format roll with appropriate support to prevent edge damage and wrinkling during application.
