AI Server and Liquid Cooling Test Solution

AI Server Motherboard and Liquid Cooling Automated Test Solution

The AI Server Motherboard and Liquid Cooling Automated Test Solution is designed for AI server, high-performance computing equipment and liquid cooling system manufacturers. It integrates server motherboard functional testing, GPU server testing, high-speed interface validation, power and power-consumption testing, liquid cooling inspection, leakage testing, thermal control testing, burn-in testing and automated data traceability into a configurable and extensible test platform. Combining software development, automated test system, test fixture and industrial automation capabilities, onTAP builds test solutions for validation, engineering launch and production testing.

Customer Challenges

  • AI server motherboards and GPU servers have complex interfaces involving high-speed signals, power, thermal management, management control and multi-module coordinated testing.
  • High-power equipment testing requires stable power supplies, loads, power-consumption acquisition and safety protection.
  • Liquid cooling system manufacturing requires leakage detection, flow, pressure, temperature control and operating-state monitoring.
  • Burn-in testing has long cycles and large data volume, requiring automated acquisition, alarms, process records and result traceability.
  • Validation, engineering launch and production testing have different needs, so the test platform must be configurable and extensible.

Solution Approach

  • Break down functional, high-speed interface, power, power-consumption, thermal-control and burn-in test flows based on server motherboard, GPU server and liquid cooling test specifications.
  • For server-board BFT, cover OpenBMC, bootloader, FRU, Linux, firmware, MES, EMMC, I/O, voltage, current and temperature checks.
  • For server PCIe expansion boards and high-speed cables, use the OTP-HyperLink Test Platform for PRBS, loopback and error analysis.
  • For DDR5-related boards, use the OTP-MemoryLink DDR5 BSI Adapter for Boundary Scan, JTAG Chain, CPU/memory connections and related power checks.
  • Develop automated test software for instrument control, equipment connectivity, sequence configuration, data acquisition, result judgment and report output.
  • Integrate power supplies, electronic loads, DMMs, DAQ, communication modules, thermal equipment, pressure/flow/leakage detection units and automation control systems.
  • Design fixtures, jigs, harnesses and safety interlocks for server motherboards, interface boards, liquid cooling components and full-system testing.
  • Build leakage testing, flow/pressure monitoring, thermal-control testing and exception protection workflows for liquid cooling systems.
  • Connect barcode, database, MES or file servers to store test parameters, burn-in process data, exception logs, results and reports.
