What is EMI
The electromagnetic compatibility (EMC) abbreviation EMC means that an electronic device neither interferes with other devices nor is it affected by other devices. Electromagnetic compatibility, like the security we are familiar with, is one of the more important indicators of product quality. Safety involves personal and property, while electromagnetic compatibility involves personal and environmental protection.
Electromagnetic waves interact with electronic components and cause interference, which is called EMI (Electromagnetic Interference). For example, a common "snowflake" on a TV screen indicates that the received signal has been disturbed.
The principle of EMI sputtering coating
Principle explanation:
1. Fill a proper amount of argon gas under high vacuum conditions;
2. Apply high-voltage direct current to ionize argon into argon ions, accelerate the impact of metal targets, and sputter metal ions;
3. The metal ions are sputtered on the substrate (molded shell) in the electric field to form a metal ion film.
Scope of application of vacuum sputtering EMI Vacuum sputtering EMI has high conductivity and high electromagnetic shielding efficiency and is widely used in communication products (mobile phones), computers (notebooks), portable electronic products, consumer electronics, network hardware (servers, etc.) ) EMI shielding for medical devices, home electronics, and aerospace and defense electronics.
Suitable for metal shielding of various plastic products (PC, PC+ABS, ABS, etc.).
EMI Sputter Coating Features
Vacuum technology is a combination of machinery, motors, materials, chemicals, and aerospace and other industries. It is also one of the top ten emerging industries that China, the United States, and Japan have strongly promoted. The application of vacuum technology has become increasingly widespread. Its applications include the optoelectronics, semiconductors, and LCD industries. In recent years, manufacturing equipment such as optoelectronics, ICs, and LCDs has grown rapidly.
EMI sputter coating has the following features:
The price is low (with domestic independent intellectual property rights).
The thickness of the vacuum sputtering processed metal film is only 0.5 to 2 μm, which does not affect the assembly.
Vacuum sputtering is a thorough environmental protection process, environmental protection and pollution-free.
There is no limitation on the material to be sputtered. Any solid conductive metal, organic or insulating material at room temperature can be used (eg copper, chromium, silver, gold, stainless steel, aluminum, cerium oxide, SiO2, etc.).
There are few restrictions on the substrate to be sputtered (ABS, PC, PP, PS, glass, ceramics, epoxy resin, etc.).
The film is dense and uniform, and the film thickness is easily controlled.
Strong adhesion (ASTM 3599 Method Test 4B).
It can be used with multiple layers of different sputtered materials. And, with the customer can change the plating order.
