Vertical, cantilever & MEMS probe card layouts—impedance control, delay matching, and RF‑aware routing for accurate wafer‑level test.
Advanced Probe Card PCB Layout
Wafer‑level testing is unforgiving: a small slip in controlled impedance or a few mils of DQ/DQS skew can close the eye, trigger false fails, and force costly re‑probes. Misaligned return paths and via stubs add reflections and jitter that erode multi‑site UPH (devices tested per hour).
Our probe card design services start with pre‑layout SI constraints and a clean pin‑map/channel plan for Advantest 93K, Teradyne J750, NI STS and more. We engineer controlled‑impedance stackups (50/100 Ω), build matched‑length groups to ±1 mil, and use RF‑aware routing with stitched reference planes and back‑drill to minimize stubs. Validation with IBIS‑AMI, TDR, and S‑parameters ensures stable, repeatable wafer‑level results—boost yield and hit the market faster.
Key Features: Up to 96 layers • Blind/buried + back‑drill • Matched length ±1 mil
Case Examples: 93K direct‑docking (20k pins) • J750 EX cantilever (663 signals)
So wafer data reflects the die—not probe‑card parasitics.
