Most laser processes are judged by how cleanly they remove material. Laser lift-off is judged by the opposite — how well the material you are not trying to touch survives.…
Drilling a hole through glass sounds like it should be a matter of finding a strong enough laser. It isn’t. Glass is transparent, brittle, and unforgiving, and the reason TGV…
Two ultrafast lasers can both say “300W” on the front of the datasheet and behave like different machines. The number is easy to compare. What it costs to reach that…
When engineers compare lasers, they reach first for wavelength and power — the two numbers printed largest on every datasheet. For materials processing, that habit skips the variable that often…
Cutting clear glass cleanly is a solved problem for most shops. Frosted and etched glass breaks that confidence — the same process that runs all day on clear stock starts…
For decades, separating dies from a wafer meant one thing: a spinning diamond blade. It still works for plenty of wafers. The reason ultrafast lasers keep taking over the hard…
The phrase “near-zero heat-affected zone” gets printed on every ultrafast laser datasheet, which makes it easy to read as a guarantee that comes with the box. It isn’t. It is…
For a decade, the through-silicon via was the obvious answer for 2.5D and 3D integration. The interesting part of the current shift is not that glass appeared — it is…
Most teams frame this as a ranking question — which mode is more sensitive, which one to standardize on. That framing is where inspection coverage quietly springs a leak. Bright-field…
The picosecond vs nanosecond laser debate usually gets framed as a quality tier — shorter pulse, better result, end of discussion. That framing sells a lot of picosecond sources for…
