An Example Observation of a Large Mounted Circuit Board Using Xslicer SMX-6000

Introduction

Printed circuit boards are densely mounted with various electronic components, an integrated circuit, and metal wiring to enable electronic devices to function effectively. Over time, the density of the components mounted on circuit boards has become increasingly high and circuit boards have become increasingly compact. For a circuit board to operate properly, its components must be defect-free and the components must be connected correctly. However, in reality the production of circuit boards involves a certain level of defects. Accordingly, there is a need for inspection methods that detect defective boards efficiently and identify the cause of the defects. Fluoroscopic observation using X-rays is one of such inspection methods. X-ray fluoroscopic observation enables efficient inspections since the internal structure of samples can be checked quickly and non-destructively. Furthermore, when circuit boards are densely mounted with components in a complex manner and as such it is difficult to inspect and analyze them by fluoroscopic observation, the cause of defects can be identified by X-ray computed tomography (CT) observation. This article introduces an example observation of a large circuit board using the Xslicer SMX-6000 microfocus X-ray inspection system that can be used for X-ray fluoroscopic observation and X-ray CT observation.
