Hydrophilic surface properties are needed in many different applications ranging from biomedical devices to marine engineering.
One of the main challenges in PCB manufacturing is the adhesion of the conformal coating. Contact angle measurements can be used to predict adhesion.
One should always measure the advancing and the receding contact angle to get the true picture of the surface wettability.
Contact angle measurements can be used in electronic manufacturing to check the surface properties of the substrate prior to the next process step.
Adhesion problems are one of the main reasons for the failure of the product. Read to find out how contact angle measurements can help solve the problem.
Due to a wide range of applications, the measurement of wettability, i.e., the contact angle measurement can be done with several different methods.
Water contact angle measurements can offer several advantages, such as better user independence and traceability, over the water break test.
The word sessile comes from the Latin word sessilis which could be translated as sitting. Sessile droplets can thus be considered as sitting droplet
Quality control is needed to detect any possible problems early on and contract angle measurement provides an excellent tool for that.
