3M 7010045136 Pcb Masking Tape 0.5in X 144yd 4.0 Mil

Product Description

The 3M 7010045136 is a polyester film masking tape engineered for printed circuit board plating processes. It features a 1 mil polyester film backing combined with a heavy coat weight silicone and rubber blended adhesive, delivering a total thickness of 3.6 mil. The tape is translucent green and is designed for use where clean removal, chemical resistance, and reliable adhesion are required during PCB masking workflows. Electronics assembly technicians and PCB fabricators use this tape to mask areas of circuit boards during plating operations where tight conformability over board contours is essential.

This tape is suited for production environments requiring consistent performance across plating, etching, and selective coating applications on printed circuit boards. The silicone and rubber blended adhesive provides excellent conformability, allowing the tape to seat cleanly over board surfaces and edges without lifting or flagging during the plating process. It comes in a 0.5 inch width by 144 yard roll, making it practical for high-volume production line use.

Key Features

• 1 mil polyester film backing for dimensional stability during plating processes
• Heavy coat weight silicone and rubber blended adhesive for strong, conformable adhesion
• 3.6 mil total tape thickness for consistent masking performance
• Translucent green color for visual identification and inspection during masking
• 0.5 inch width suited for precision masking of narrow PCB features and traces
• 144 yard roll length supports extended production runs without frequent changeouts

Compatibility

Designed as an OEM-style masking solution for printed circuit board plating and related PCB fabrication processes requiring a conformable polyester film tape.

Installation Notes

Application should be performed by qualified PCB fabrication or electronics assembly technicians familiar with masking procedures. Ensure the board surface is clean and free of oils, flux residue, or moisture before applying the tape to achieve full adhesive contact. Remove the tape promptly after the plating or coating process is complete, following the adhesive manufacturer's recommended dwell time guidance, to reduce the risk of adhesive residue transfer. Store unused rolls in a cool, dry environment away from direct UV exposure to maintain adhesive performance.
