Signal Integrity Spring Probe Catalog Highlights

  • We use a clad metal process for our barrels. Clad metal barrels are a big advantage over plated barrels, especially at pitches at or below 0.5mm.
  • Low contact resistance design features
  • Long contact life
  • Smooth non-stick operation over hundreds of thousands of cycles.
  • Custom spring design for consistent, low variance force.
  • Full range of Z-Height to fit your handler kit.
  • Full range of pitch diameters to fit package and die contact centers from 0.2mm to 1.0mm.
  • Wide selection of DUT side contact shapes and materials
    • Tip shapes include 60° conic, 4 point crown, reduced crown, Ogive, and 90° hemisphere.
