Silver Conductive Copper Foil Tape for EMI Shielding & Stained Glass (33M, 5 Rolls)

Achieve superior electromagnetic shielding and seamless craft soldering with this Single-Sided Conductive Copper Foil Tape with Silver Adhesive Backing. Manufactured from 99.98% pure electrolytic copper foil (0.055mm / 55-micron total thickness) and coated on one side with high-conductivity silver-filled acrylic adhesive, this tape provides low contact resistance, continuous electrical grounding, and reliable thermal stability across 33-meter rolls. Sold in convenient packs of 5 rolls across popular widths (5mm, 6mm, 8mm, 10mm).

Key Features

• 99.98% Pure Electrolytic Copper Foil: Premium soft copper foil conforms smoothly to curved contours, irregular edges, and embossed surfaces without tearing.
• Conductive Silver Acrylic Adhesive: High-tack adhesive layer is impregnated with conductive particles, ensuring direct electrical continuity through the adhesive side to grounded metal surfaces.
• Readily Solderable Surface: Smooth, clean copper face bonds readily with lead and lead-free solder, making it the industry standard for stained glass foil wrapping and PCB trace jumpering.
• Exceptional EMI & RFI Shielding: Effectively attenuates high-frequency electromagnetic interference, eliminating background buzz, RF crosstalk, and hum in sensitive audio gear and electronic circuits.
• Thermal & Weather Resilience: Rated for continuous operation from -10°C to 120°C (14°F to 248°F) with strong holding power (1.3–1.5 kg/25mm).

Recommended Applications

• Stained Glass Crafting & Soldering: Wrapping glass pieces prior to soldering to create strong, clean solder beads.
• Guitar & Bass Cavity Shielding: Lining pickup cavities, control cavities, and pickguards to eliminate hum and 60-cycle buzz.
• Electronics & Appliance EMI Shielding: Suppressing electromagnetic radiation in laptops, smartphones, monitors, transformers, and power supplies.
• PCB Circuit Prototyping & Repair: Creating flexible conductive traces, antenna connections, and grounding jumper jumpers.
• Static Dissipation & ESD Grounding: Safely draining electrostatic charges in sensitive electronic workstations.

Application Instructions

• Clean Surface: Ensure the bonding substrate is clean, dry, and free of dust, oils, or oxidation (wipe with isopropyl alcohol).
• Peel & Position: Peel away the protective paper liner and apply the copper tape along the seam or channel.
• Burnish Smoothly: Press firmly using a plastic squeegee, burnisher, or wooden roller to activate the pressure-sensitive adhesive and eliminate air pockets.

Package Includes: 5 × Rolls of Silver Conductive Copper Foil Tape (33M Length each, Width as selected).
