DINGTouch:Introduction to EMI Shielding Film

Introduction to EMI Shielding Film

1. Definition and Function

EMI shielding film is a specialized functional material designed to reduce the effects of electromagnetic interference (EMI) and radio waves.
By forming a shielding layer inside the device, it minimizes electromagnetic noise generated by resistive touch panels, LCD, and electronic circuits.

Its main functions include:

• Internal Noise Shielding: Prevents electromagnetic waves generated by the device itself (such as PC, LCD, and control boards) from leaking outward.

• External Interference Protection: Blocks electromagnetic waves from the surrounding environment, ensuring stable operation of electronic components.

2. Types of EMI Noise

Electromagnetic interference can be categorized into two main types:

• Conducted Noise: Transmitted through conductors such as power lines, signal cables, and PCB wiring.

• Radiated Noise: Emitted into the air in the form of electromagnetic waves, affecting surrounding devices.

EMI shielding film effectively reduces both types of noise, thereby improving the system’s electromagnetic compatibility (EMC).

3. Application Environments

EMI shielding film is widely used in industries and scenarios where high reliability is critical:

• Marine Equipment: Protects key navigation and control systems from EMI.

• Aviation Equipment: Ensures stable operation of flight control and communication systems.

• Medical Equipment: Prevents external electromagnetic waves from interfering with the accuracy of medical instruments.

• Industrial and Scientific Instruments: Maintains stability in high-precision measurement and control environments.

4. Features and Advantages

• Excellent EMI Shielding Performance: Effectively suppresses electromagnetic interference for stable system operation.

• Flexibility: Can be bent or applied to fit device structures.

• Lightweight and Thin: Adds minimal size and weight, suitable for portable or embedded devices.

• High Reliability: Designed to perform in harsh environments such as high humidity, vibration, and salt mist.
