U.S. Faces Security Risks from Chinese-Made PCBs in AI Technology

• •U.S. Defense Department mandates domestic PCB sourcing due to security risks.
• •Only 4% of PCBs are now produced in the U.S., down from 30%.
• •PCB prices have increased by up to 40% amid supply chain disruptions.

The U.S. is increasingly concerned about the security risks posed by printed circuit boards (PCBs) manufactured in China, which are essential for AI technologies, including Nvidia chips. The Defense Department is mandating that most of its PCB purchases come from domestic sources due to fears of malicious components being embedded in these boards. The share of PCBs produced in the U.S. has plummeted from 30% to just 4%, raising alarms about a 'risky dependency' on Chinese manufacturing. Experts warn that compromised PCBs could lead to severe consequences, such as missile malfunctions. The U.S. government is considering subsidies to boost domestic PCB production amid rising tensions with China over AI supremacy. Companies like TTM Technologies and Sanmina are experiencing significant growth but struggle to meet military demand. PCB prices have surged by up to 40% recently due to supply chain disruptions caused by ongoing conflicts in the Middle East and Ukraine.
