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.
- Tip Material: Plated Tool Steel, Plated BeCu, Solid Precious Metal Alloy
- PCB Interface plunger shape – standard smooth spherical. Selections for Crown and Conic tips as well.
