THE LEAD

The US and Philippines plan a major industrial hub to secure semiconductor supply chains, while new quantum research suggests AI infrastructure costs could face disruption from far lower-cost computing alternatives.

TECH NEWS

Chinese researcher demonstrated a small-scale quantum system outperforming AI weather prediction centers that can cost over $100M, achieving results at less than 1 percent of the cost.

Researchers highlight non-Hermitian electronic sensors using exceptional points and parity-time symmetry to improve sensitivity, while noting challenges around noise and system complexity.

Researchers developed a microwave-based method that precisely cures conductive inks during 3-D printing, enabling circuits to be formed on heat-sensitive materials without damage.

Rosel manufactured a pilot batch of flexible-rigid “book” PCBs designed for spacecraft.

TM Soldering Solutions launches Phoenix selective soldering platform.

Just months after leaving Qualcomm, distinguished CPU and system architects Gerard Williams, John Bruno, and Ram Srinivasan have established a new CPU startup that promises no less than to “rewrite the rules of silicon.”

Wally Rhines discusses the latest ECAD market data, highlighting continued growth trends and emerging risks across design tools and semiconductor software in the PCB Chat podcast.

FOCUS ON BUSINESS
Trendspotting Again
While it may seem as if there is little rhyme or reason for variations in demand, the reality is that the electronics manufacturing service (EMS) industry’s repeating cycles actually make trends fairly predictable.

DESIGNER'S NOTEBOOK
Tolerances and Dimensions for PCB Fabrication
When it comes to coloring in the fabrication drawing, the way we provide the data creates the space the fabricator must fill. For each datapoint, there is a least material condition (LMC), a maximum material condition (MMC) and a nominal.
