Introduction
A magnetron sputtering coater is a device based on magnetron sputtering technology. It uses magnetic field constrained ions to bombard targets, depositing uniform, dense films on substrates.
Why it's good: It is known for producing uniform, dense films with strong adhesion.
What it's for: Widely used for coating hardware parts, as well as functional coating in fields like semiconductors, optical lenses, and cutting tools.
Magnetron Sputtering Coating
Magnetron sputtering is a plasma coating process whereby sputtering material is ejected due to bombardment of ions to the target surface. The vacuum chamber of the PVD coating machine is filled with an inert gas, such as argon. By applying a high voltage, a glow discharge is created, resulting in acceleration of ions to the target surface and a plasma coating. The argon-ions will eject sputtering materials from the target surface (sputtering), resulting in a sputtered coating layer on the products in front of the target. Magnetron sputtering technology is characterized by:
* A water-cooled target, so little radiation heat is generated
* Almost any metallic target material can be sputtered without decomposition
* Non-conductive materials can be sputtered by using radio frequency (RF)
or medium frequency (MF) power
* Oxide coatings can be sputtered (reactive sputtering)
* Excellent layer uniformity
* Very smooth sputtered coatings (no droplets)
* Cathodes (of up to 2 meter long) can be put in any position, therefore high
flexibility of sputtering equipment design
The machine offers coatings in various metal colors such as gold, rose gold, silver, steel, nickel, bronze, anthracite and black. The color of the coating is determined by its composition, which is composed of zirconium, titanium, nitrogen, carbon, oxygen and other metals. Our process engineering team can fine tune the color according to your requirements, so that you may be unique in your market.
It is widely used in watchband, watchcases, jewelry, smart phone, electronic products, sanitary ware, golf hardware, tableware, cosmetics etc. lt can deposit all kinds of decorative coatings such as TiN, TiC, TiCN, TiAlN, CrN etc and Af coatings.

Structure:
It is composed of a pulse power supply module, a magnetron sputtering chamber, a target material assembly, a vacuum system, a substrate transmission and temperature control unit, as well as an online monitoring system, etc.
Working principle:
By outputting a pulse voltage with a frequency ranging from 10 to 350kHz, target sputtering is achieved in the negative voltage stage, and electrons are introduced in the positive voltage stage to neutralize the accumulated positive charges on the target surface. During operation, the chamber is first evacuated to a vacuum and working gases such as argon are introduced. After the pulse power supply applies voltage, the gas is ionized to form plasma. Under the constraint of the magnetic field, the plasma bombards the target material, causing the atoms or molecules of the target material to detach and deposit on the surface of the substrate to form a film.
Features
The pulse parameters are flexible and adjustable:
The equipment can precisely adjust core parameters such as pulse frequency, duty cycle, and peak power, adapting to different target materials and coating requirements. By adjusting the duty cycle, the heat generation of the target material and the sputtering rate can also be balanced. Some high-end models can achieve a pulse frequency of up to 150kHz, which can meet the deposition requirements of complex film layers.
Compatible with diverse target materials and substrates:
It can not only handle metal targets such as Ti and Al, but also achieve stable sputtering of insulating targets such as Al₂O₃ and TiO₂ through bidirectional pulse or medium-frequency AC modes. Moreover, the low-temperature process design can be adapted to different material substrates such as glass, plastic, and PET, and is particularly suitable for coating heat-sensitive substrates like flexible OLeds.
High degree of integration and intelligence:
Mainstream models are equipped with multiple integrated vacuum manipulators, online film thickness monitoring, and automatic alignment systems, supporting continuous production in multiple chambers.
Advantages
Significantly reduce film layer defects:
The periodic working mode of the pulse power supply can effectively suppress the arc discharge on the target surface and reduce film defects. At the same time, high-power pulses can generate high-density plasma, making the film layer denser.
Enhance resource utilization and economic efficiency:
The target material utilization rate of the equipment can be increased from 20% to 45%, the target material consumption can be reduced by 40%, and the cost of using rare metals such as ITO can be reduced by 30%. Moreover, the deposition rate can reach 10nm/s, significantly enhancing production efficiency.
Avoiding the problem of target poisoning:
During the deposition of oxide, nitride and other compound films, the reaction gas adsorbed on the target surface can be desorbed during the pulse interval, preventing the formation of an insulating layer on the target surface and solving the problem of target poisoning in traditional DC magnetron sputtering that makes sputtering unsustainable.
