When the Q - cloth (quartz cloth) material of NVIDIA's Rubin M9 computing platform undergoes a revolutionary upgrade - with its Mohs hardness soaring to 7 and a significant increase in fiber densification, traditional super - hard tungsten steel drill bits fall into a predicament of "a cliff - like decline in lifespan and out - of - control yield". The drilling lifespan drops sharply from 1000 holes to just 100 - 200 holes. Frequent bit replacements lead to a drastic plunge in machine utilization rates, and the pollution from grinding residues further inflates rework costs. This industry transformation not only brings challenges but also spawns opportunities for high - end consumables substitution. LINKUT's PCD diamond drill bit is the key solution to this problem.

As a leading enterprise deeply rooted in the field of super - hard material processing, LINKUT keenly perceives the technical demands behind the upgrade of Q - cloth material. Relying on years of accumulation in diamond tool research and development, it has introduced PCD diamond micro - drill bits customized for high - hardness quartz - cloth PCBs. The product uses polycrystalline diamond with a Mohs hardness of 10 as its core material, perfectly matching the high - hardness and high - density characteristics of Q - cloth. The drilling lifespan exceeds 2000 holes per bit, more than 10 times that of traditional tungsten - steel drill bits. It fundamentally addresses the three major industry pain points of "frequent bit replacement, low yield, and pollution residue", and has become a core cooperative consumable for major PCB manufacturers such as TTM Technologies during the Q - cloth verification stage.

The Total Cost of Ownership Advantage Defines a New Benchmark for High - end PCB Processing

Market concerns about the "single - bit price of over 1000 yuan" of PCD drill bits have been completely dispelled by the Total Cost of Ownership (TCO) model in actual production scenarios. Taking a medium - sized production line with a daily processing task of 200,000 holes as an example, LINKUT's PCD drill bits achieve the optimal comprehensive cost with three core advantages:

Efficiency Revolution

With an ultra - long lifespan of 2000 holes per bit, the frequency of bit replacement drops from 2000 times per day for tungsten - steel drill bits to 100 times per day. The downtime for bit replacement is reduced by 95%, and the effective machine utilization rate increases to over 98%. This significantly reduces implicit costs such as equipment depreciation and labor.

Yield Assurance

It maintains an ultra - high yield of 99.5% throughout the process. The smoothness of the hole wall and the accuracy of the hole diameter far exceed industry standards. The rework cost is 80% lower than that of tungsten - steel drill bits, completely avoiding the chain losses in subsequent processes of high - grade PCBs.

Cost Control

Although the single - bit price is higher than that of tungsten - steel drill bits, the bit cost per hole is only 0.5 yuan when spread out. Adding the bit - replacement cost (0.0025 yuan per hole) and the rework cost (0.02 yuan per hole), the comprehensive cost per hole is only 15% - 25% higher than that of "low - priced and low - efficiency" tungsten - steel drill bits. However, it can ensure core values such as on - time delivery rates and customer reputation.

For high - end PCB manufacturers pursuing "high efficiency, high yield, and high stability", LINKUT's PCD drill bits are by no means "cost - increasing items" but rather "core assets" that guarantee production capacity, control risks, and enhance competitiveness.

Technology Empowerment + Production Capacity Assurance: LINKUT Leads the Industry Substitution Wave

LINKUT always adheres to the core strategy of "driving industry upgrading through technological innovation" and has established three core barriers in the field of PCD diamond drill bits:

Customized R & D

Aiming at the quartz - fiber characteristics of Q - cloth, it optimizes the diamond grain arrangement and drill - bit geometric structure. The drill - bit lifespan is 30% higher than the industry average, and it can meet the processing requirements for ultra - fine hole diameters of less than 0.1mm.

Large - scale Production

It owns an industry - leading intelligent manufacturing production line for diamond tools, with an annual production capacity of over 1 million bits. It can meet the bulk supply demands of global high - end PCB manufacturers, and the delivery cycle is shortened to 7 - 10 days.

Full - chain Service

It provides a one - stop solution from product selection, process adaptation to on - site debugging, and cooperates with customers to complete the full - process verification of Q - cloth processing. Currently, it has reached long - term cooperation with several leading PCB enterprises, and its products have been successfully applied in the production of high - end PCBs for AI servers, high - speed communication equipment, etc.

As the NVIDIA M9 board approaches mass production countdown, the demand for high - end PCBs in fields such as AI servers and fourth - generation semiconductors continues to explode. The market size of PCD diamond micro - drill bits is expected to quickly exceed the 10 - billion - yuan mark. With its comprehensive advantages in material research and development, production - capacity scale, and customer service, LINKUT is becoming the core driver of this industry substitution revolution, helping global PCB enterprises overcome technical difficulties and seize market opportunities.

Choosing LINKUT's PCD diamond drill bits means choosing to keep pace with industry transformation, empower production with technology, and win the future through innovation.
