A season - for distance and perspective

December 3, 2025

At this time of year, when daylight shortens and the horizon retreats into early dusk, we’re reminded how often progress begins with the willingness to look beyond what is immediately in front of us. The story of the telescope is rooted in that impulse — the desire to make the distant understandable, to bring faraway worlds within the reach of human thought.

A century ago, Earl C. Slipher stood beneath a cold desert sky at Lowell Observatory and directed a massive refractor toward Mars. Working with fragile glass plates and equipment that strained against the limits of its era, he fought atmospheric distortion, long exposures, and the patient uncertainty of early astronomical photography. Yet, despite these constraints, he produced something extraordinary - high quality photography that could extend human perception over millions of kilometers.

Today, we follow that same logic, though our gaze is no longer cast into the heavens. Instead of distant planets, we examine the internal landscapes of advanced electronics. When an X-ray beam from the FYNE NF4 passes through a C4 solder bump on a graphics processing unit (GPU), it highlights defects in the manufacturing process that can cause critical failures during device operation. The resulting image echoes the astronomy of Slipher’s era: clusters of bright spheres, isolated voids, and silent orbits frozen within a grainy universe of matter.

What Slipher once traced across celestial bodies, we now uncover inside matter itself: voids appearing like small planets, defects drifting like moons, and hidden structures emerging with a clarity impossible through conventional sight.

The telescope allowed us to reach outward. X-ray imaging allows us to reach inward. Both transform distance, whether cosmic or microscopic, into understanding.

Warm wishes for the season. 

Best regards, 
Comet X-ray

Need for Speed: Boosting X-ray Inspection Speed in Advanced Electronics

October 28, 2026

As electronics become more powerful and advanced packaging technologies more complex, manufacturers face the challenge of detecting ever-smaller defects without reducing throughput. Optical inspection methods cannot reveal the buried structures found in high-power electronics, chiplets, HBM, through glass vias (TGVs), and advanced 3D packages. X-ray inspection and automated X-ray inspection (AXI) provide the required visibility, but higher resolution and penetration have traditionally come at the expense of speed. Recent advances in micro and nano focus X-ray source technology are overcoming this trade-off by delivering higher photon flux, improved contrast-to-noise ratio, and faster imaging. In this post we review these developments in high-power electronics, where higher voltage and power are required to penetrate through dense structures while maintaining micro-scale imaging, and advanced packaging where increasing complexity from vertical integration and sub-micron resolution combine. We highlight how increased throughput can be achieved while maintaining reliable defect detection.

Focus topic. A conversation with Jan Bressendorff and Allen Gress about pipeline weld inspection

October 8, 2026

On a pipeline job, the X-ray system is chosen for the weld, not from a catalog. Pipe size and access determine how the crew can inspect it. The procedure sets what the image must show. Heat, weight and exposure time shape the working day. A poor choice can cost hours. A good one helps the crew get an image the inspector can assess without needless delay.
