One of the main challenges in PCB manufacturing is the adhesion of the conformal coating. Contact angle measurements can be used to predict adhesion.
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.
Work of adhesion is defined as a work required to separate two phases from each other.
While contact angle goniometry has been around for many years, we have recently developed a way to account for the underlying surface’s micro-scale roughness.
