How to Choose Backing Plates for Sputtering Targets?
When you are choosing backing plates for sputtering targets, it is important to consider the compatibility of the materials, the thermal conductivity, and the mechanical strength. These factors will help you choose a backing plate that will work best for your project.
The most important factor is the material properties of the backing plates and their expected operating temperatures. Copper, Aluminum, Molybdenum, and Stainless Steel are the main materials used for backing plates. They each have different properties that make them better suited for certain applications.
As a professional sputtering targets manufacturer, we can help you select the right backing plate for your needs to ensure optimal performance of your sputtering process.
What is Backing Plate for Sputtering Target?
Sputtering is one of the main techniques for preparing thin film materials. It uses ions generated by ion sources to accelerate and aggregate in a vacuum to form high-speed energy ion beams, bombard the solid surface, and exchange kinetic energy between ions and solid surface atoms.
The atoms on the solid surface leave the solid and deposit on the surface of the substrate, and the bombarded solid material is called a sputtering target.
The backing plate is a key component in the sputtering process, providing support for the sputtering target and fixing it to the sputtering apparatus. In addition, the back plate also functions to dissipate heat generated during sputtering.
How to choose the raw material for the Backing plate?
The most common backing plate materials are Copper and Stainless Steel. The properties of these materials make them ideal for sputtering target applications. When selecting a backing plate material, it is important to consider compatibility with the sputtering target material.
Copper(oxygen-free copper):
Because it has good electrical and thermal conductivity and is easy to process. If properly maintained, the oxygen-free copper backplane can be reused more than ten times.
Stainless Steel:
Currently, stainless steel tubes are most commonly used as back tubes for rotating targets. Stainless steel pipes have good strength and thermal conductivity and are very economical.
There are a few other materials that are sometimes used for backing plates, but they are less common. These include molybdenum, tungsten, and graphite.
Molybdenum:
It has a high melting point and is resistant to corrosion, making it a good choice for high-temperature applications.
Tungsten:
Tungsten is also resistant to corrosion and has a high melting point, but it is much heavier than other backing plate materials. Graphite is lightweight and has good thermal conductivity, but it can be difficult to work with.

Important Factors to Consider
When choosing a backing plate for a sputtering target, there are several important factors to consider.
1, The backing plate must adhere well to the target, while also providing good electrical contact.
2, make sure that the backing plate has good thermal conductivity so that it can dissipate the heat generated by sputtering. It should be able to cool the target and target assembly effectively.
3, In addition, consider the mechanical strength of the backing plate. The backing plate needs to be strong enough to support the weight of the target and withstand the stresses of sputtering.
Keep in mind that sputtering targets are only effective when they're used correctly.
If you follow these above tips, your target will be able to deliver optimal results for any application!
