Solder (after ion etching)

Paper applied with an adhesive (sticky note)

Welcome to the world of LEXT 3D

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.

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.
