The purpose of depositing indium film on metal bars is to create a conductive layer on the surface of the metal. This allows for easier prototyping and testing of electronic components on the metal bar.
This method is considered a cheap prototyping method because it does not require expensive equipment or materials. It is also a relatively quick and simple process, making it a more efficient option for smaller scale projects.
The process involves heating the metal bar, typically made of copper or aluminum, to a high temperature. Then, a thin layer of indium is applied to the surface using a vacuum deposition method. The metal bar is then cooled and the indium film is left on the surface.
Indium film is a highly conductive material, making it ideal for testing and prototyping electronic components. It also has a low melting point, allowing for easy application and removal if needed. Additionally, the film is durable and can withstand high temperatures and harsh environments.
One limitation of depositing indium film on metal bars is that it may not be suitable for large-scale production. This method is best suited for smaller scale prototyping and testing. Additionally, the equipment and materials needed for this process may not be readily available in all settings.
