Guide Plates for Probe Cards

WOP delivers Ceramic Plates and Glass Plates for the probe cards industry – an essential component for guiding probes for microchip inspection at the correct position.

We offer rapid prototyping and production services for your individual designs.

The semiconductor industry further minimizing contact sizes and increasing density requires novel solutions to meet today’s market needs.

While conventional processing methods cannot keep up with feature size minimization at the same quality level, we offer industry-leading processing technology and experience.

We ensure:

  • Ultra-high precision & quality
  • Rapid prototyping
  • Heat and force resistance
  • Small feature sizes
  • Diverse materials: ceramic (silicon carbide, silicon nitride) and many types of glasses
  • High aspect ratios unachievable with alternative technologies
  • Ultra-high precision
  • Fast prototyping
  • Heat and force resistance
  • All types of shapes
  • Small feature sizes
  • Diverse materials - ceramics, glass

Typical features

  • Circular, square, and other-shaped holes
  • Straight hole cross-section | no taper
  • Low chipping <10 μm
  • Smooth sidewalls, Ra <1 μm
  • Typical min. hole size 20 µm (circular)
  • Wafer size up to 200 mm x 200 mm (8”)
  • Wafer thickness from 30 µm to 10 mm
  • Positional accuracy ±3 µm
  • No debris on back and front surfaces
  • No sagging around holes
  • Aspect ratio up to 1:100
  • High throughput and yield
  • Ability to work with metalized glass types (e.g. Au, Pt, Ni, Cr, Mo)
  • Minimal or no post-processing is needed

Why choose glass?

While we achieve outstanding results with both – glass and ceramics, we suggest thinking of using GLASS for your guide plates.

  • Glass manufacturing time is 20 times faster than ceramics. It will allow you to start testing sooner.
  • Ultra-high precision & quality on glass ensures more accurate testing.
  • There are 80% fewer defects while using glass. It will save you money and time.
