Strain gauge precision stress meter
By measuring the substrate distortion with a sensor, the internal stress of the plating can be measured in real time.
It is possible to measure the stress at each plating time (film thickness) with a single measurement. Additionally, stress measurements can be conducted when re-plating on a previously plated film. It can measure fine stresses that conventional stress meters could not detect. It is used by inserting a dedicated stress meter board into the slot of the precision plating power supply YPP series.
