3M 7000144698 Pcb Masking Tape 0.25in X 72yd

Product Description

The 3M 7000144698 is a green polyester film tape engineered for printed circuit board masking during electroplating operations. Built on a 4.0 mil polyester film backing with a silicone and rubber adhesive blend, it delivers a conformable, residue-resistant bond that holds through plating baths without lifting or flagging. The tape measures 0.25 inches wide and runs 72 yards per roll, making it well suited for precision masking of traces, pads, and connector areas where clean lines and reliable adhesion are critical to process quality.

This tape is used in electronics manufacturing and PCB assembly environments where selective electroplating requires a reliable masking barrier. It is appropriate for both production-line and bench-level rework applications. Electronics technicians, PCB fabricators, and assembly professionals select this product when process control and clean removal after plating are priorities. Its green color aids visual inspection during and after the masking process.

Key Features

• 4.0 mil polyester film backing provides dimensional stability during electroplating
• Silicone and rubber adhesive blend conforms to surface contours on PCBs
• 0.25 inch width suited for fine masking of traces and small component areas
• 72-yard roll length reduces changeover frequency in production settings
• Green color supports visual inspection and tape location verification

Compatibility

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

Installation Notes

Application is typically performed by electronics assembly technicians or PCB fabrication personnel. Ensure the board surface is clean and free of flux residue or oils before applying tape to achieve full adhesive contact. Remove tape promptly after the plating process is complete to minimize adhesive transfer risk. No special tools are required, but precision cutting tools or tape dispensers are recommended for consistent width and edge quality.
