Load Boards

DUT to ATE precision interfaces

Poorly engineered load boards can trigger production delays, costly retests, and unstable yield data. In high volume semiconductor testing, every hour counts. CONNECT LOGIC delivers precision layout and simulation engineered to perform in high stress production, so you move faster with confidence.

Load Board FAQs

What is ATE load board design?

PCB layout and simulation that interfaces your DUT to the tester (e.g., Teradyne J750, Ultraflex/Ultraflex Plus, Advantest 93K, T2000, NI STS), optimized for signal integrity and power delivery.

Do you run simulations?

Yes pre-layout SI/PI rules plus IBIS-AMI, TDR, S-parameters, eye diagrams for DDR/PCIe/USB/MIPI and SERDES to 112 Gbps.

How fast can you deliver a load board layout?

Typical 1–3 weeks depending on complexity; rush options available.

Can you layout high-speed RF load boards?

Yes, controlled impedance ±5%, RF/microwave routing, HDI microvias, and back-drill for stub removal; cosimulation (S-parameters/TDR) as needed.

What do I receive at release?

Stackup & constraints, Gerbers/ODB++, drill, fab/assembly notes, BOM (as needed), and simulation reports.

Do you support platform-specific constraints?

Yes, we tune materials, stackups, and routing rules for Teradyne/Advantest/NI resources.

Regions served?

We serve globally, primarily the USA, plus Canada, Europe, Singapore, Malaysia, Taiwan, Germany, and Japan.

NDA & confidentiality?

Absolutely, we work under your NDA and keep data protected.
