AGY launches new L-HDI glass fibre, completing AI-centric product portfolio

AGY enables AI with the most advanced glass fibre solutions

This product marks a significant milestone for AGY, as L-HDI completes the company’s AI-focused glass fibre portfolio, which now includes a full range of solutions optimised for the semiconductor, high-performance computing and advanced networking sectors. The L-HDI product provides dimensional stability, thermal reliability and mechanical integrity essential for AI-specific integrated circuit packaging, particularly for High-Density Interconnect (HDI) and substrate core materials.

“With the introduction of L-HDI, AGY now offers a complete portfolio of glass fibre products tailored to AI infrastructure,” said Patrick Hunter, executive vice president, commercial at AGY. “As AI systems evolve and require more precise, thermally stable materials, AGY is proud to meet this demand with next-generation glass fibre technologies manufactured right here in the United States.”

The key features of L-HDI are an ultra-Low CTE for improved warpage control in IC substrates, high modulus to resist deformation when exposed to heat and mechanical stress and an excellent dimensional stability under high thermal cycles. It is also optimised for IC substrate manufacturing and made in the USA, to support domestic supply chain resilience.

AGY’s glass fibre offerings – including L, L2 and now L-HDI – are used across a range of AI-enabling components, from optical transceivers and high-speed routers to IC substrates and semiconductor packaging.

As AI infrastructure continues to scale globally, AGY remains committed to developing and supplying the most advanced glass fibre solutions from its operations in Aiken, South Carolina. The addition of L-HDI reaffirms AGY’s leadership in performance materials for the world’s AI-driven digital transformation.
