List of Sputtering Targets for Shield Coating

Characteristics of sputtering coating for shielding (EMI)

Shielding (EMI) sputtering coating has the following characteristics:

1. Low price.

2. The metal film's thickness is only 0.5-2 μ m, which does not affect the assembly.

3. Environmentally friendly process, absolutely environmentally friendly and pollution-free

4. There is no limit to sputtering materials.

List of sputtering targets for shield coating

So, what are the sputtering targets that can be used for shield coating? There are copper, chromium, silver, gold, stainless steel, aluminum, silicon dioxide and so on. The details are as follows:

Silver Sputtering Target

Silver is a soft, lustrous element that belongs to the metals' transition group on the periodic table. It has a melting point of 962 ℃, a density of 10.5 g/cc, and vapor pressure of 10-4 Torr at 1,105 ℃. Silver has been used since ancient times in countless products. It is ductile, malleable, and the most electrically conductive of all metals. It is considered a precious metal and can be found in jewelry, solders, paints, and mirrors. It is evaporated under vacuum to produce semiconductors, sensors, fuel cells, and optical coatings.

Copper Sputtering Target

Copper is a ductile metal with very high thermal conductivity, electrical conductivity, ductility, corrosion resistance. A freshly exposed surface of pure copper has a reddish-orange color. High-purity copper is used as various wires in the electronics industry, bonding wires for electronic packaging, high-quality audio cables and integrated circuits, liquid crystal display sputtering targets, and ion plating. It is also an indispensable valuable material in atomic energy, rockets, missiles, aviation, space navigation, and metallurgical industries. AEM provides high purity OFC, Cupronickel, and alloy products as requested.

Aluminum Sputtering Target

Aluminum is a silvery-white, metallic material. It can be found in kitchen utensils, cars, street lights, and aluminum foil in food packaging. Although it is not a strong material, it is a good conductor of heat and electricity and can form an oxide layer resistant to corrosion.  If evaporated in a vacuum, aluminum layers form a reflective coating found on telescopes, automotive headlamps, mirrors, packages, and toys. The aluminum sputtering target is widely used in the aerospace, automotive lighting, OLED, and optical industries. Some high purity aluminum targets are used in the semiconductor chip, flat panel display, and solar cell industries.

Chromium Sputtering Target

Chromium is a steely-grey, lustrous, hard, and brittle metal that takes a high polish resists tarnishing, and has a high melting point. Chromium sputtering targets are widely used in hardware tool coating, decorative coating, and flat display coating. Hardware coating is used in various mechanical and metallurgical applications such as robot tools, turning tools, molds (casting, stamping). The film's thickness is generally 2~10um, and the film requires high hardness, low wear, impact resistance, and resistance with thermal shock and high adhesion property. Chromium sputtering targets are commonly applied in the glass coating industry. The most important application is the preparation of automotive rearview mirrors. With the increasing requirements of automotive rearview mirrors, many companies have switched from the original aluminizing process to the vacuum sputtering chromium process.
