Advantages of Using Indium Bonds

Indium bonding is an application of sputtering target bonding. If you’re looking for metallization techniques that enhance the quality of the bond in a major way, then consider this bonding application. Some advantages are:

Thermal Conduction & Durability

Indium bonding is very well-known and often used because of its powerful thermal conductivity. Because it has a greater resistance to high temperatures, the bond is also long-lasting.

Heat Extraction

The bond is an ideal and efficient way to eliminate heat from any target. Therefore, operators find it easier to work with the material.


If you are looking for a bond that is more malleable than other bonding solders out in the market, indium bonding fits the bill quite nicely. By using a malleable bond, cracks and other common wear and tears—which could lead to issues and problems—are less likely to happen.

Low Melting Point

Some of the best bonds have a low melting point. The bonds must be able to remove stress when dissimilar materials cool to help lessen the extent of the damage caused by warping.

Finding the Right Bonding Manufacturer

Not all manufacturers provide the same results in regard to bond quality. Therefore, it’s best to choose the most reliable company.

In order to make sure you’re dealing with a quality bonding manufacturer, it’s advisable to check for the following:

  • Experience. Pick a company that has been in the business long enough to know how to get things done and done right.
  • Reputation. Chances are, if a company has already been around for more than a few years, they have built a reputation. Make sure that they have a good reputation, and if not, look elsewhere.
  • Reliability. Choose a company that is known for its dedication, or one that has a history of providing quality results.
  • Trustworthiness. Protect your business against unscrupulous providers. Ask around and look for companies that you feel you can trust.

Indium Bonding – The Process Explained

Chemistry and science are more than just school subjects to many people. These people may remember sitting in a classroom mesmerized by the periodic table of elements and imagining collecting all the elements and noting their different properties. If you had this problem, well, then you are fortunate to know about ACI ALLOYS.

At ACI Alloys, we believe in manufacturing reliable products for leading industrial and academic groups, and we want people to understand what we do. We stock almost every element, know their properties well and stand behind our products.

Indium bonding is one of the many services we provide and here is some background information on what is used and the process:


Indium is a chemical element that is considered a post-transition metal. All that really means is that it sits between transitional metals and the metalloids in the periodic table of elements. It is a soft metal that has a low melting point when compared to other metals and it is most often associated with zinc and tin. Its low melting point combined with its thermal and electrical properties make it especially useful in the bonding process.

Indium can serve a variety of uses and purposes, such as creating alloys, photoconductors, and thermistors, and is considered a non-toxic alternative to the highly toxic mercury.

The Bonding Process

We specialize in quick turnaround times for any bonding process. With the indium bonding process, we can guarantee the quality of the bond through ultrasonic testing. Due to Indium’s malleable properties and low temperature, it is an ideal metal to be used in bonding. This malleability means that it can be flexible with the thermal expansion of the target when it differs from the backing plate. One aspect of indium bonding to keep in mind is that since indium does have a low melting point, you have to be careful to have sufficient cooling to be sure not to exceed 150 degrees Celsius during the sputtering process.

Whatever your needs are regarding Indium bonding, we can help fulfill them and answer any questions you may have.

Thin Film Materials-Overview and Common Applications

Thin films have thousands uses for both of everyday items and highly specialized technologies. Using thin film materials or rather the application of a thin film to a product or component is called deposition. The term deposition, itself, is really any technique that affixes a fine layer of material onto a substrate or the surface of an object. Generally, this process is accomplished through two main categories of deposition–chemical deposition or via physical deposition.

For example, everyday household mirrors were previously made using a similar technique known as silvering. Today, the application of different materials to other components typically occurs either with optical coatings or electronic semiconductor devices. Here, at ACI Alloys, we offer a thin film material for all types of applications. We can make high purity custom alloys, precious metals, ceramics and non-precious metals.

Commonly Used Types of Thin Film Materials

As previously mentioned, other commonly used films include a range of metals, non-metals such as ceramics and PVD materials all of which are ideal for creating specific kinds of thin films. Depending on your specific needs, materials that are affixed or sputtered using Physical Vapor Deposition (PVD) can be customized to the level of quality and the exact size you desire. We can also provide ceramics- ceramic films are another commonly used to creates a protective layer against oxidation, wear and corrosion.

Typically, this particular material is perfect for extending the longevity of tools as well as other products or components that are prone to wear and tear. Ultimately, if you are having trouble finding the material you hope to use for your application, our experts at ACI Alloys have the experience to find a way to make the thin film materials that you need.

The Difference between Physical and Chemical Deposition

With chemical deposition, fluid precursors essentially change a solid surface on a chemical level. In other words, a particular fluid surrounds a solid component and the process of deposition therefore occurs completely on every surface without any real opportunity for customization. Physical deposition, on the other hand, uses electromechanical, thermodynamic or mechanical methods to create the film or coating.

Benefits of Thin Film Application

The benefits of thin film application are almost endless, since films, PVD materials and coatings are used in almost every industry. Typically, coatings and films provide a specific protective function.
