It can be confirmed without loss by the "sampling method that protects the surface" of the adhered layer (approximately 20nm) on the surface of the connector terminal plated with STEM.
In STEM (Scanning Transmission Electron Microscopy) and EDS (Energy Dispersive X-ray Spectroscopy), information about the composition of the sample (contrast images reflecting atomic numbers) can be obtained by scanning a finely focused electron beam over the sample. The following features are also available: - Observation of changes in diffraction contrast by varying the angle of incidence of the electron beam - Determination of whether the observation target is crystalline - Acquisition of information about crystal defects (dislocations, twins, etc.) within the crystal In this case, we will introduce "Failure Analysis of Au-Plated Connector Terminal Contacts Using STEM." Please take a moment to read the PDF materials. Additionally, our company conducts various cross-sectional analyses using not only STEM but also TEM and SEM. We would be happy to assist you, so please feel free to reach out. Seiko Future Creation Official Website https://www.seiko-sfc.co.jp/ *Other materials are also available.

basic information
● The sampling method that protects the surface allows for the confirmation of the adhesion layer on the terminal surface (approximately 20nm) without loss. ● According to the EDS analysis results, the main components of the adhesion are C (carbon) and O (oxygen), indicating that the contact failure is due to organic contamination. ● For more details, please contact us or download the catalog.
