AI server demand triggers PCB drill bit shortage and capacity expansion by Topoint and Keyware
Monday, March 2, 2026 at 03:22 AM
The surge in AI server demand is creating a critical shortage of PCB drill bits as high-layer count designs (40+ layers) for Nvidia GPUs and ASICs utilize harder ultra-low-loss materials like M7 and M8 CCL. These materials reduce drill bit lifespan from 3,000 hits to under 800, leading to a shift where multiple bits are required per hole. In response, Topoint is investing NT$560 million in a new factory in Taoyuan for premium coated bits, while Keyware is expanding capacity to 15 million units per month by Q1 2026. Tight supply has already triggered early signs of price increases across the supply chain.
Context
The surge in AI server demand has triggered a global shortage of micro drill bits used in high-end PCB manufacturing. As AI-grade copper clad laminates become denser and more abrasive, the lifespan of a single drill bit has plummeted from 3,000 hits to fewer than 800, and as low as 100 for premium materials. To maintain yields, manufacturers are increasingly banning re-sharpened bits in favor of new units, causing consumption to explode. This supply-demand imbalance is driving price hikes across the sector, benefiting specialized toolmakers like Union Tool.
Key suppliers are aggressively expanding capacity to capture this high-margin growth. Topoint is investing NT$560 million to boost monthly capacity to 35 million units near major clients like Unimicron and Gold Circuit Electronics. Similarly, Kaiwei aims for 15 million units monthly by Q1 2026, with order backlogs already reaching Q3 2026. This equipment cycle also benefits related manufacturers like Long-term Precision and Aura as the industry shifts toward high-value coated drills.
