Special Methods for Testing Tensile Strength
While most of our analytical methods are conventional, we had to be more creative about tensile strength. The conventional method would require us to send in samples on a near daily basis, because bath parameters can change quickly under certain circumstances.
Especially with thicker layers the control of tensile strength is very important to avoid deformation of base parts.
Which is why we evaluate a concurrent sample every day on a self-developed measuring tool for convexity/concavity of the sample.
Also, on a weekly basis, we test the baths’ depositions at different electric currents.
