Tabletop-SEM has been developed with compact design and minimization of Module for normal SEM.  It is easy to use for everyone and has reasonable price. It is used for the purpose of development, quality assurance or etc in corporations, government offices and universities.

The image quality of the sample has decreased at the request of the client company.

Generally, except in special cases, it is natural that solder points of PCB exist, and this causes many problems.

The sections of the solder pad and the solder ball that were taken with SEM are shown in the picture on the left below.

The boundary can be clearly checked by the difference in components, and it can be clearly identified through component analysis, as shown in the image on the right below.

As shown in the images as bleow, the components of the Solder ball and pad can be identified through EDS (Energy Dispersive X-ray Spectrometer) analyses, and the images can be separately identified (the exact ingredients have been deleted by customer’s requirements).
