0.027mm Burrs in Micro-Hole Drilling: The Ultrasonic Precision Standard Redefines Probe Card Manufacturing

The semiconductor industry’s relentless push for smaller, faster chips has made probe cards—the critical consumable hardware enabling wafer testing—more challenging to manufacturers than ever. As the bridge between test equipment and microscopic chip circuits, probe cards directly determine which dies get packaged… and which become costly scrap.


Why Probe Card Manufacturing Hits a Wall

While global players dominate this $3B+ market, rising geopolitical tensions and supply chain risks have accelerated demand for domestic alternatives. But producing high-performance probe cards—especially engineering plastic (PEEK/PI/VESPEL) variants for 5G/AI chips—faces four deal-breaking hurdles:


  • Micro-hole burring (0.095mm+ burrs distort high-frequency signals)

  • Sub-0.3mm hole drilling with ±1μm consistency across 10,000+ holes

  • Thermal warping from plastics’ low melting points during machining

  • Tool adhesion causing surface defects in soft, viscous materials


The Ultrasonic Edge: Data That Speaks Volumes


Conprofe’s UEM-600 Ultrasonic-Green Engraving and Milling Center + Solid PCD Micro Drill does not just incrementally improve these pain points—it redefines benchmarks:

  • True D0.22mm/ D0.31mm micro holes with ATAN angle accuracy of 25.462° (standard: 25.463°)

  • High accuracy and stability in high-density micro-hole drilling of engineering plastic materials (Vespel SCP-5000)
