One of the main challenges in PCB manufacturing is the adhesion of the conformal coating. Contact angle measurements can be used to predict adhesion.

HMDS is used to render the surface of silicon more hydrophobic and thus to match better with the chemistry of the photoresist.
In the context of QCM-based instrumentation, 'dissipation' or ‘damping’ are often mentioned. Read about what these concepts mean, and why are they relevant.
One should always measure the advancing and the receding contact angle to get the true picture of the surface wettability.
QCM-D and QCM-R both collect information about the energy loss. Read about how these thow methods compare.
Contact angle measurements can be used in electronic manufacturing to check the surface properties of the substrate prior to the next process step.
Learn about the difference between primary and secondary batteries, and about battery performance indicators.
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.
