[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] What is the GLAD Sputtering Technique? There are various techniques for increasing the quality of thin films deposited by vacuum coating methods. GLAD Sputtering (Glancing Angle Deposition) or OLA (Oblique Angle Deposition) is one of the most widely used techniques in the sputtering deposition process. GLAD method helps to achieve different microstructural architectures and increases the surface area of thin films. In the GLAD Sputtering, you could make an array of periodic microstructures to increase the surface sensitivity.

Deposition of the Highly Reactive Materials

Thermal evaporation

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] Deposition of the highly reactive materials There are materials with a high affinity to oxygen among the materials which are deposited by the vacuum coating systems. If these substances are in the vicinity of a small amount of oxygen, they react quickly and burn completely. Lithium is easily oxidized when exposed to air. On the other hand, this alkali metal and its compounds have many applications in the industry. For example, this metal is used to produce rechargeable batteries that are used in smartphones, tablets, etc. The best way to lithium deposition is the thermal evaporation method.

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] What is Plasma Cleaning? Surface cleaning using plasma is an economical way to clean specimens uniformly and securely through plasma treatment. Removal of contaminants from the studied substrates without affecting the overall properties of the material is one of the benefits of the plasma surface cleaning method. Plasma cleaning is widely used in the circuit industry, including cleaning the PCB board before coating and cleaning the lead frames during the packaging process. Plasma sample cleaning has significant advantages over other surface cleaning methods as it applies to a wide range of materials, is eco-friendly, residual-free, and effective in highly sensitive applications like cleaning medical equipment.
