Examples of observing intermetallic compounds through etching treatment.

アイテス
The method of processing the observation samples may result in different information being obtained. You may have observed the solder joints in two dimensions from a cross-section, but have you ever wondered how the compounds are growing in three dimensions? In this document, we present examples of observations of the Cu pad and solder joint. We include both "cross-sectional observation" and "planar observation."
