QUALITY ASSURANCE SYSTEM

Rigorous QA Standards & Traceable Fulfillment

Connecting Hong Kong procurement governance with mainland manufacturing, assembly and testing facilities to provide standardized hardware QC for integrators and data centers.

STAGE 01 Visual & Authenticity

Physical Integrity & Serial Verification

Cross-referencing exact OEM part numbers (MPN), batch revisions, tamper seals and barcodes. Full physical inspection of chassis sheet metal, PCB traces, gold edge fingers and CPU socket pins for any sign of oxidation or transit damage.

Key checkpoints: S/N consistency · Tamper-evident seals · Pin visual audit · Chassis geometry
STAGE 02 Architecture & Microcode

Component Architecture & Firmware Audit

Verifying CPU stepping revisions, DRAM SPD parameters, multi-channel DIMM rank pairing, NVMe/SAS firmware levels, and motherboard PCIe bifurcation topologies on certified test benches.

Key checkpoints: BIOS/BMC baseline · Memory rank pairing · PCIe 5.0 link width · Topology scan
STAGE 03 Burn-in Diagnostics

24-48h Burn-in & Stress Diagnostics

Running prolonged continuous burn-in based on project tier. Deploying Linpack/Prime95 compute stress, MemTest86 ECC diagnostics, GPU matrix compute stress, and enterprise storage continuous IOPS cycles while monitoring thermals and power ripple stability.

Key checkpoints: Thermal logging · Zero ECC errors · GPU temperature curve · PCIe stability check
STAGE 04 ESD & Heavy-duty Packaging

Mil-Spec ESD & High-Density Shock Shielding

Components heat-sealed in military-spec ESD shielding bags. Complete server chassis and high-value accelerator cards cushioned with custom high-density EPE foam molding, 5-layer heavy-duty export cartons, desiccant packs, and steel-banded pallets.

Key checkpoints: ESD bag seal · EPE shock absorption · Drop/shock indicator tags · Export strapping
STAGE 05 Traceability & Compliance

Full Traceability, QA Sign-off & Export Clearance

Generating formal QA sign-off certificates with detailed hardware serial manifests, stress logs, and engineer sign-offs. Coordinated with Hong Kong trade documentation, export customs clearance, and end-use compliance records.

Key checkpoints: Engineer-signed certificate · Serial packing list · Export customs filings · Traceability archive
