A common occurrence is the weakening or delay of signals due to electromagnetic interference (EMI) interacting with electronic components. To mitigate this, a layer of silver paste is often silk-screened onto the surface of Mylar to prevent such interference. EMI structures generally come in two types: a "grid-like" structure covering only parts of the surface, and a full-screen covering. Both serve the same purpose of shielding interference, differing mainly in appearance. EMI structures, characterized by high conductivity and electromagnetic shielding efficiency, are printed above Mylar (viewed from the front of the product) as Electrostatic Discharge Control (ESD). EMI primarily aims to prevent static electricity from harming target electronics and surrounding products.
1. Printing is used on the conductive film (PET-Metal Dome Array) of the pot slice to control the impedance of the printing surface to 0.1Ω or below, creating a blocking effect on electrical noise and static electricity to achieve a floating sound quality effect.
2. It serves as a protective circuit when static electricity penetrates.
3. Compared to existing single-layer or double-layer conductive films, the manufacturing process is more complex.
4. It exhibits strong adaptability to continuously changing climates.

Light Guide Film (LGF), also known as LGP (Light Guide Plate), is characterized by its ultra-thin profile, uniform illumination, and versatile color display. It is primarily used in mobile phone keypads, serving as a product that converts the point light source of LEDs into a surface light source through colored LGF. LGF is applied onto existing double-layer or EMI structure conductive films to achieve optimal light distribution.
The working principle of LGF involves utilizing the principles of light reflection and refraction, combined with specialized optical software design. Microstructure processing is applied to the optical fiber film, enlarging the "point light source" into a "surface light source." Light beams propagate from the medium at suitable angles and densities, resulting in excellent uniform illumination.
The design of LGF conductive film/LGP can reduce the need for several LED lights, addressing issues such as uneven brightness distribution, high power consumption, large space occupancy, and high costs.
- LGF is a transparent thin film with high refractive index and light transmittance, featuring surface microstructures of varying densities.
- LGF utilizes the phenomenon of total internal reflection due to differences in refractive index between media, guiding light rays to emit from the surface through the disruption of microstructures.
- LGF is a low-cost and low-energy-consumption light-conducting material.
1. It produces excellent luminous effects with uniform brightness and high light intensity.
2. It is lightweight, flexible, and thin, with a thickness of 0.125mm, making it suitable for use in mobile phones without occupying significant space compared to light guide plates.
3. It saves LED lights, reduces power consumption, and cuts costs.
4. Its structure does not have special requirements for circuit components.

5. The raised dome switch buttons are designed to avoid gaps in the product, preventing moisture from seeping in and causing delamination.
1. Adding domes is primarily due to insufficient height, with restrictions on the height and size of the tactile dome.
2. Many dome additions are because the switch was previously mechanical and later changed to a membrane switch.
3. There are internal structural issues with the product, such as the low pillars of rubber buttons.
4. UV adhesive cures under ultraviolet light and will inevitably wear out.
5. The material of the domes is also special, currently only one type available, with a thickness of 0.04mm.
6. Standard PET thickness and color are selected according to specifications and must be transparent.
7. The higher the dome, the greater the risk of detachment and the shorter the lifespan. It is recommended to be within 0.4mm, with most heights around 0.25mm.
8. The cost of domes is also relatively high.
Shenzhen Zigeng mainly produces conductive films on single or double-layer Mylar with an additional dome of height 0.1~0.25mm and diameter 0.5mm~1.5mm to meet specific structural combinations, enhancing the tactile feel of the dome. The finished product, using 4mm or 5mm circular or elliptical domes with conductive films, has a total height of 0.35~0.50mm. It is mainly used in mobile phones, network telephones, various remote controls, MP3/MP4 players, radios, digital cameras, learning machines, game control keyboards, microwaves, car dashboards, telescopes, toys, etc. Compared to the polyester membrane switches used in the past, it offers better tactile feedback and longer lifespan.
