What is the quality of your coatings?
UPDATE: newsletter december 2016 “coating and film testing”
Maintaining high-quality coatings and films is an important requirement within the semiconductor industry. The xyztec “Scratch Test” provides a new means of measuring the quality of the adhesive bond of single or multiple coatings to the substrate and/or each other. As shown in the video a special shear tool is used to land on to a coating or multiple coatings and then scratch along the surface.
The depth of the cut and layer being tested can be controlled by a programmable landing force and the ability to drive down into the coating or coatings to a programmable depth. Weak bonds can be seen in the failure mode of delamination and the force-displacement graph of the shear tool. In the example shown the difference between a good and bad bond can be clearly seen.
