## Glass Fiber Shortage: AI and Apple in the Crosshairs The global supply chain is under pressure due to a shortage of glass fiber, an essential component for manufacturing printed circuit boards and other electronic components. This critical situation threatens to slow down the production of AI hardware and could impact Apple's plans for its 2026 devices. Glass fiber is a composite material made of glass and resin, widely used in electronics for its electrical insulation, mechanical strength, and thermal stability properties. Its shortage could lead to cost increases and delivery delays for numerous tech products. Companies in the sector are closely monitoring the situation and seeking alternative sources of supply, but resolving the issue may require significant time and investment.
