AI Compute Board Test Fixtures & Systems
Custom test fixture and electrical test system design & fabrication for AI servers and GPU modules
“You define the spec — we deliver the hardware system”
We focus on the hardware layer of AI server and HPC board testing — from mechanical design to fixture fabrication to instrument verification. We do not develop test software or algorithms, complementing our customers' test core competencies.
Scope of Service
Mechanical Structure Design
Fixture structure, precision alignment, press mechanisms, shielding and thermal design
RF Signal Path Planning
HF probe selection, RF interface adaptation, signal path optimization, grounding and shielding
Electrical Test Hardware Integration
Test system hardware integration on Keysight and other mainstream instrument platforms
Verified Delivery
S-parameter verification with network analyzers; fixture + test report delivered

You define the test spec — we handle the hardware, from mechanical design to fixture fabrication to instrument verification.
Hardware Test Fixture Specs
Reference parameters for AI board hardware fixtures — mechanical, RF signal path, contact and shielding. Actual specs are defined per test-plan.
| Metric | Value | Notes |
|---|---|---|
| Board Types | GPU / TPU / NPU Modules | Incl. accelerator & compute cards |
| Alignment Accuracy | ±0.05 mm | Mechanical + Vision composite |
| Contact Method | POGO / Spring Probe | Selected per signal band |
| Signal Bandwidth | DC – 40 GHz | RF probe path customizable |
| Shielding Level | ≥ 60 dB @ 6 GHz | Incl. EM shielding chamber design |
| Press-Force Control | 10 – 500 N programmable | Force-position loop · protects board |
| Thermal Solution | Air / Liquid / Cold plate | Matches customer test power |
| Interface Protocol | PXI / GPIB / LAN | Interfaces with customer instruments |
