Solder (after ion etching)

Because solder is very soft, years of experience and know-how are required to make specimen preparations before observing the composition of solder under a microscope. Polished surface techniques using the ion etching method have made considerable progress in recent years. The image shown below is the surface of solder processed with the ion etching method. This image shows that the tin (Sn) layer (white part) is made smoother by using the ion etching method. An SEM requires vapor deposition, whereas LEXT does not require pretreatment. Therefore, by using LEXT a specimen can be observed in its actual state.

Paper applied with an adhesive (sticky note)

Sticky notes are widely used for the convenient feature of applying, peeling and applying again. Minute spherical adhesives are distributed where an adhesive is applied to a sticky note, as shown in the image below. The way they are distributed, the thickness of an adhesive, etc., are thought to determine the ease of use (merchantability) of sticky notes. Using LEXT, such adhesives and paper (fiber) can be observed and measured without pretreatment in a noncontact manner.
