Rigaku Corporation, a group company of Rigaku Holdings Corporation and a global solutions partner in X-ray analytical instrumentation, will introduce the DicifferX™ Microarea Edition at JASIS 2026. This X-ray diffractometer enables materials characterization of microareas only a few tens of micrometers in size in a laboratory environment. As electronic devices become smaller, electronic components such as multilayer ceramic capacitors (MLCCs) are becoming increasingly miniaturized and more densely integrated, driving demand for materials characterization of microareas only a few tens of micrometers in size. Conventional micro-area measurements present challenges such as the loss of X-ray intensity caused by reducing the beam size and shifts in the irradiation position caused by even slight mechanical deflection of the instrument. Purpose-built to overcome these technical challenges, the DicifferX Microarea Edition enables stable measurement of micro-areas at the scale of a few tens of micrometers.
