4. Alignment

For best results, generally the tweezer jaws should be aligned central to the sample. Jaw features like serrations, hooks or cavities must be correctly engaged in the vertical axis as well. A sufficiently advanced bond tester can in many cases assist the operator by aligning automatically. This works by vision technology or the detection of surfaces.
