HP, Dell flag 2027 PCB squeeze as AI servers eat laminate

A new customer ordering printed circuit boards today will not take delivery before late 2028. The leading copper-clad laminate supplier already has order visibility to 2030. One Taiwanese PC maker told Nikkei Asia that laminate costs have risen at least 12-fold since July.

Those are the flat numbers in Nikkei's report on the AI squeeze reaching a component nobody worried about a year ago. As HP and Dell executives map 2027 supply, the paper writes, "a mundane component has emerged as an unlikely concern." The constraint sits two steps below the chip: in laminate, in the specialty fiberglass cloth the laminate is built from, and in the tooling that turns both into finished boards.

AI boards need more layers and lower signal loss than commodity boards, and chip packaging substrates are growing larger. Suppliers are triaging accordingly. Ordinary server PCB lead times are now approaching a year.

Material physics does not help. Nitto Denko controls roughly 90% of the global T-glass market, and new capacity for the specialty fiberglass cloth is not expected to come online until mid-2027 at the earliest. On October 20, the chairman of Taiwanese substrate maker Unimicron Technology warned that some key materials could be short by about 20% in 2027, and that delivery times for chip-substrate production equipment are extending to as long as 30 months.

The money is already moving. Amazon has taken a stake worth about NT$1.59 billion in Taiwanese PCB maker Gold Circuit Electronics, extending a cloud push into the physical layer that follows earlier scrambles for HBM and CoWoS tracked in our AI infrastructure coverage. The pattern of AI eating a commodity and PC buyers landing at the back of the queue rhymes with this week's news that HP, Asus and Acer are shifting some PC production back to China under AI cost pressure.
