Introduction

Shield tape is a type of adhesive tape used primarily for electromagnetic interference (EMI) and radio frequency interference (RFI) shielding applications. It is designed to protect electronic components and signal integrity by reducing or eliminating the interference that can cause malfunction or degradation of performance in electronic systems.

Applications of Shield Tape

Shield tape finds utility in various sectors due to its ability to mitigate EMI and RFI. Key applications include:

• Electronics Manufacturing: Shield tape is used to line electronic housings, ensuring components are protected from external electromagnetic disturbances.
• Telecommunications: This tape is critical in the manufacturing of telecommunication devices where signal integrity is paramount.
• Automotive Industry: Vehicles employ shield tape to protect sensitive electronic systems from interference.
• Aerospace: Essential in aerospace applications due to the high sensitivity of avionics systems.
• Medical Devices: Shielding is crucial to prevent external signals from interfering with medical device functionality.

Technical Specifications

Key specifications of shield tape products include:

• Conductivity: 0.003 ohms/sq maximum for copper-based tape.
• Adhesive Strength: 1.5 kg/25 mm at 180° peel strength.
• Temperature Range: -40°C to 120°C, ensuring performance across diverse environments.
• Shielding Effectiveness: Up to 80 dB across a frequency range of 10 kHz to 18 GHz.

Numerical Analysis

A comparative analysis of shield tape effectiveness shows that:

• A 10% increase in tape width correlates with a 5% improvement in EMI shielding effectiveness.
• Shield tape applied with a 25% overlap yields a 15% increase in protection compared to non-overlapped configurations.
• Reduction in electronic device failure rates by 30% to 40% when shield tape is utilized properly in assembly.
