Cold Machining Solutions for High-Quality Custom Probe Cards
The global probe card substrate market is experiencing rapid growth at a CAGR of 10–12%. Driven by the intense demand for High-Quality Custom Probe Cards, femtosecond laser processing is quickly replacing traditional methods. With its multi-material compatibility, unparalleled consistency, and exceptional production yield, MONO is emerging as a key player in breaking the global monopoly on micro-drilling technology.
The Explosive Growth of Semiconductor Test Interfaces
With the rapid advancement of 5G, millimeter-wave RFICs, and logic SoCs, semiconductor wafer inspection interfaces are transitioning from hundreds of pins to arrays of tens of thousands. Market data indicates that the global probe card substrate market is entering an explosive growth phase.
Amid this trend, whether for logic or memory chips, the demand from overseas clients and top-tier testing facilities for High-Quality Custom Probe Cards has never been higher. However, as the pitch between probes continues to shrink, the micro-machining difficulty of probe card guide plates is increasing exponentially. This demands manufacturing equipment with extreme precision, rock-solid stability, and flexible customization capabilities.
Complete Material Customization: Fulfilling the Foundation of Custom Probe Cards
The substrate materials used in customized probe cards vary widely, each with vastly different thermal properties and optical absorption rates. MONO's femtosecond equipment demonstrates unmatched process compatibility, easily switching between materials on the same platform:
- Semiconductor Test Ceramics: Including high-hardness Alumina (Al2O3), Silicon Nitride (Si3N4), and Aluminum Nitride (AlN).
- Composite Packaging Substrates: Glass, silicon, or multi-layer PCB hybrids.
Whether the requirement calls for circular holes, custom-shaped square holes, micro-grooves, text etching, or convex-concave structures, MONO can achieve multi-functional, integrated processing on a single substrate through free programming.
Why MONO Fs-laser?
When seeking custom solutions, many clients ask: "Can your equipment machine square holes under 100µm with zero taper? How is the batch consistency?"
MONO's answer is a confident yes—with exceptional consistency. Our real-world case studies, which demonstrate roundness controlled within 1µm across arrays of tens of thousands of holes, prove the ultra-high stability of our femtosecond equipment:
- Breaking Physical Limits: To meet fine pitch challenges, we are not only machining square holes under 30µm, but pushing toward 25µm and even 20µm. Our ultra-small R-corner control has broken the 3µm barrier, reaching as low as ≤0.4µm.
- Eliminating Thermal Damage: Because probe cards endure high-frequency testing over long periods, the structural strength of the substrate is vital. MONO's femtosecond lasers deliver true cold machining, ensuring zero micro-cracks and zero edge chipping (Ra <0.2µm). This effectively guarantees the lifespan of expensive ceramic plates.

Climbing Penetration Rates: Femtosecond Lasers are Reshaping Semiconductor Testing
Industry data reveals that the penetration rate of femtosecond laser technology in probe card substrate processing has leaped from approximately 5% in 2019 to around 18% in 2024, and is expected to surpass 30% within the next three years.
From R&D to mass production, MONO's processing yield of 98.5% is a testament to its disruptive capabilities in high-precision energy control.
