Measuring Contact Angle,Interfacial Tension And Wettability in Electronics Industry

Electronics industry provides electrical circuits involving active electrical components. Integrated circuits that are used in electrical and electronic devices are built on wafers made of semiconductor materials. Silicon is the most used semiconducting material. Silicon wafers are made of extremely pure silicon, which requires a high quality control. Polymers are also used in the electronic industry as insulating layers in the fabrication of chips and chip carriers. By using our product brand Attension, Tensiometry can be widely utilized in the electronics industry to characterize different material properties.
Application examples include:

• Cleanliness of silicon wafers and circuit boards is an important factor to ensure the optimized functionality of the final product. Contact angle measurements with optical tensiometers can be used to study cleanliness of silicon wafers and circuit boards during the manufacturing process. • Semiconducting wafers are typically processed with protecting coatings. Quality and uniformity of these coatings can be studied with contact angle measurements. • Wettability and interfacial tension are important characteristics of soldering systems used in electronics industry. The molten solder alloy needs to wet both metal surfaces in order for the surfaces to link. Wettability of molten solder on metal can be defined by contact angleforce tensiometer. measurements with

Measuring Contact Angle & Surface Tension In Energy Industry

Real-World Implications Case Studies Within the Oil & Gas industry, several case studies exemplify the advantages derived from conducting surface property measurements

Enhanced Water-Oil Separation 

Scenario: In an offshore oil production platform, the production stream includes a significant amount of water, which forms an emulsion with the crude oil due to high surface tension. Application: By lowering surface tension using appropriate surfactants, contact angle and surface energy measurements can guide the selection of the most effective chemicals. This optimization improves emulsion destabilization, allowing for more efficient water-oil separation and reduced energy consumption during processing

Scenario: Enhanced oil recovery (EOR) methods are employed in a mature oil reservoir to recover more oil. Contact angle measurements are used to assess the wettability of the reservoir rock. Researchers discovered that the rock has mixed wettability characteristics. Application: By altering the contact angle using specific surfactants or polymers, surface energy measurements help design a more effective EOR strategy. This increases oil recovery by modifying the interaction between the reservoir rock and injected fluids

Scenario: Offshore pipelines are exposed to harsh seawater conditions, leading to corrosion and reduced lifespan. Engineers apply hydrophobic coatings to the pipeline surfaces. Sliding angle measurements help evaluate the performance of these coatings. Application: By achieving a low sliding angle, the coatings effectively repel water and reduce the risk of corrosion, extending the life of the pipeline and reducing maintenance costs
