What is Microfocus X-ray Technology? (Basic Knowledge)

The focal spot size of an X-ray source directly influences image sharpness. When inspecting components such as ICs (as shown in the comparison), a smaller focal spot size significantly reduces geometric blur, resulting in a clearer, higher-resolution image.

Conventional X-ray sources, such as those often used in general medical radiography, typically have focal spot sizes measured in millimeters. While effective for larger structures, these sources naturally produce geometric unsharpness (blur) when high magnification is required.

In contrast, microfocus X-ray sources feature focal spot sizes measured in micrometers (microns). By minimizing the source size, these systems achieve superior spatial resolution. They are essential for non-destructive testing (NDT) applications where high magnification and detailed imaging are critical.

When relying on visual data for quality assurance, image clarity is paramount. High-resolution microfocus X-ray systems allow operators to clearly identify minute defects and abnormalities in electronics, precision mechanical parts, and advanced materials.
