COBRA®

The stencil that won’t quit.

Our patented COBRA® stencil technology delivers ultra-smooth aperture walls (Ra ≤ 0.17µm) through a proprietary surface refinement—not a coating—ensuring consistent paste release, reduced defects, and extended service life. With 150,000+ controlled print cycles and compatibility with aggressive cleaning processes, COBRA® is the gold standard for high-yield SMT printing.

Key Advantages

  • Ra ≤ 0.17µm – Smoother than natural laser-cut surfaces (7.79µm) for flawless paste transfer

  • 5+ Years Field-Proven Durability – Resists wear from squeegee friction and cleaning

  • Stainless Steel Fine Grain (3370-410 HV) – High hardness for long-term tension stability

  • ±5µm Aperture & Fiducial Tolerances – IPC-7525 compliant, ideal for 01005 (and smaller), µBGAs, and other challenging geometries/designs.

  • No Burrs, No Contamination – Laser-cut with edge radius ≤5µm for clean releases

  • Area ratio 0.4 (0.2 testing in progress), proven performance

Performance & Compatibility

  • Aperture Coining: >1° for thicknesses <6 mils

  • Fiducial Alignment: ±5µm to pad (laser-etched for easy targeting)

  • Tension Stability: 28–35 N/cm² (optimal performance >35 N/cm²)

  • Frame Options: Green/Gray Tubular or Space Saver

Durability & Maintenance

  • Lifespan: 150,000+ print cycles (with proper care)

  • Cleaning: Resists IPA, plasma, and ultrasonic methods

  • No special cleaning or maintenance process required to sustain COBRA® aperture finish
