Direct-current power supply magnetron sputtering coating equipment pvd coating machine

Core conclusion:
1.Dc magnetron sputtering coating equipment is a magnetron sputtering technology driven by DC power supply.

2.It features a simple structure and controllable cost, mainly focusing on the efficient preparation of metal films. It is widely used in mid-to-low-end industrial and basic coating scenarios.

Equipment Introduction:
It uses direct current high voltage to ionize inert gas (commonly argon) to generate plasma. By confining electrons through a magnetic field, the movement path is extended, enhancing the collision efficiency between the plasma and the target material. As a result, the atoms of the target material (which must be a conductive material) are sputtered and deposited on the surface of the substrate to form a film.

2.The equipment has a compact structure and is easy to operate. It is mainly used for preparing metal films, alloy films, etc., and is suitable for batch production and basic functional coating requirements.

Core features:
1.It is powered by a DC power supply, with a simple circuit structure and relatively low manufacturing and operating costs of the equipment.

2.It is only compatible with conductive target materials (such as aluminum, copper, chromium, titanium and other metal targets), and cannot directly use insulating ceramic targets.

3.The sputtering rate is stable, and the film thickness is easy to control, making it suitable for continuous and large-scale production.

4.The magnetic field design is diverse (such as balanced magnetron and unbalanced magnetron), and the adhesion and density of the film layer can be adjusted according to the requirements.

Main advantages:
1.The operation threshold is low, parameter adjustment is simple, maintenance is convenient, and the later operation and maintenance cost is low.

2.The metal film preparation efficiency is high, the sputtering rate is superior to that of radio frequency magnetron sputtering, and the energy consumption is lower.

3.The film layer has high purity, good uniformity and excellent surface smoothness, meeting the basic functional and decorative requirements.
The equipment has strong stability, a low failure rate, is suitable for long-term continuous operation, and offers high production cost performance.

Typical applications
1.In the field of decoration: Coating metal decorative films (such as aluminum films, chromium films) for hardware accessories, furniture accessories, jewelry, etc.

2.In the field of electronics: Preparing metal conductive films for electronic components (such as electrode films for capacitors and lead films for circuit boards).

3.In the packaging field: Coating barrier films (such as aluminum foil composite films) for plastic films and metal foils to enhance their barrier properties against oxygen and moisture.

4.In the field of tools and machinery: Coating wear-resistant metal films for common cutting tools and mechanical parts to enhance surface hardness and wear resistance.

5.Other scenarios: Preparing basic functional films such as conductive films for solar cell backsheets and reflective films for architectural glass.
