Low-Temp Solders Are Suddenly Critical For Chiplets And Photonics


Key Takeaways: Tin-bismuth-based solders enable reduced warpage and compatibility with silicon photonics and other temperature-sensitive components. A novel soldering process using white light could help prevent cracks in flip-chip BGA package solder balls, while reducing the carbon footprint. Hypoeutectic Sn-Bi based solders prove especially promising as an SAC305 replacement. ... » read more

New Panel Production Efforts Target Interposer Costs


The rising cost of increasingly large interposers is spurring renewed interest in panel-level manufacturing, which for years has hobbled along due to the massive and collective effort required by the chip industry to change formats. Several companies are developing their own processes, although there is currently no commercial production. And a new consortium called Joint3, spearheaded by Ja... » read more
