Sources: China's export curbs on critical metals have disrupted supplies of micro drill bits made mainly from tungsten carbide, used in PCBs and chip substrates (Cheng Ting-Fang/Nikkei Asia)
Recent export curbs imposed by China on critical metals have actively disrupted the availability of micro drill bits. These specialized tools are predominantly fabricated from tungsten carbide to handle precise manufacturing tasks. Consequently, the shortage impacts the global technology supply chain because the drill bits are essential for manufacturing both printed circuit boards and chip substrates.

The eighth-generation tablet brings significant premium engineering to Apple's compact lineup, including an OLED screen and certified IP67 water resistance for the first time. However, a sharp £200 price increase narrows the gap with larger alternatives like the 11-inch iPad Air M4. Prospective buyers must balance top-tier processing power and lighter portability against persistent omissions like a 60Hz screen limit and Touch ID.
Structural assessments after seismic events often depend on visual inspections that easily miss internal fractures threatening a building's integrity. To address these dangerous blind spots, structural engineer Aldrei Ong developed a concrete spacer block that acts as a real-time damage monitor. This technology provides an early warning mechanism to help engineers identify compromised infrastructure before catastrophic structural failure occurs.
