What Is Gold Finger Electronics Polyimide Tape? |https://www.lvmeikapton.com/

Introduction

Gold Finger Electronics Polyimide Tape is a high-performance adhesive tape made from polyimide film, a material known for its exceptional thermal stability and electrical insulation. It is widely used in PCB (Printed Circuit Board) manufacturing, especially for protecting gold-plated connectors ("gold fingers") during soldering and reflow processes.

Unlike conventional tapes, PI material high temperature resistant 300 tape can withstand extreme heat (up to 300°C) without degrading, making it indispensable in electronics, aerospace, and automotive applications.

Key Features of Gold Finger Electronics Polyimide Tape

1. Extreme Temperature Resistance (PI Material High Temperature Resistant 300 Tape)

• Operating Range: -269°C to +300°C

• Short-term Peak Resistance: Up to 400°C for brief exposures

• Does not melt, shrink, or lose adhesion under high heat

Comparison with Other Tapes

2. Strong Adhesion and Blocking High Temperature Tape

• Silicone-based adhesive ensures strong bonding even in thermal cycling conditions.

• No residue upon removal, preventing damage to sensitive components.

3. Electrical Insulation (lvmeikapton Insulating Electrical Tape)

• Dielectric Strength: ≥6 kV/mm

• Volume Resistivity: 1×10¹⁷ Ω·cm

4. Chemical and Moisture Resistance

• Resists acids, solvents, and oils

• Low moisture absorption (<1%)

Applications of Gold Finger Electronics Polyimide Tape

1. PCB Manufacturing (Brown Circuit Board High Temperature Tape)
