Two-Phase D2C Cold Plate CNC
CNC machining support for two-phase direct-to-chip cold plate hardware where leak-path control and micro-channel consistency drive deployment readiness.
Thermal precision-interface route
This thermal route stays in the adjacent advanced-hardware lane: leak-path CTQs, channel geometry, sealing datums, inspection evidence, and prototype-to-pilot release planning.
Core bottleneck: AI thermal teams face rising heat flux while available two-phase-ready cold plate supply remains constrained.
Program Gallery
Manufacturable Scope
- Copper and stainless cold-plate interface machining
- Micro-channel geometry control aligned to drawing CTQs
- Pilot-to-repeat workflow for thermal hardware programs
Representative Part Scope
- Two-phase cold plate base block
- Vapor return interface manifold section
- Sealing-face adapter and threaded ports
- Serviceable cold plate cover structures
Proof Checkpoints
- Helium leak test setup can be applied per customer-specified pressure differential and acceptance threshold
- CMM verification on channel depth, flatness, and sealing datums before release
- Thread gauges and surface-finish checks on leak-critical interfaces
Materials & Process Focus
- Material compatibility with selected working fluid
- Leak-path stack tolerance and sealing surface integrity
- Channel geometry repeatability at pilot and repeat batch stages
Evaluation Matrix
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Leak validation path | Helium leak test or pressure-hold per RFQ acceptance | Two-phase cooling risk is dominated by leak-path failures and sealing defects. |
| Micro-channel tolerance capability | Drawing-defined CTQ verification with CMM checkpoints | Small channel deviations can change thermal and pressure behavior materially. |
Risk Controls
- Bench leak pass but rack integration leak appears later: Freeze gasket, thread, and torque assumptions at RFQ stage and test against customer-defined boundary conditions.
- Overexpectation on full thermal-loop performance guarantee: Scope guarantee to machined geometry and agreed inspection/test method; system-level thermal behavior remains customer architecture responsibility.
Buyer FAQ
Do you guarantee zero leakage in any system condition?
Leak outcomes are qualified only under agreed test setup and acceptance criteria. System-level conditions outside that envelope require additional validation.
Can we start with an urgent prototype lot first?
Yes. We can stage prototype-first machining and lock CTQ checkpoints before repeat supply.

Upload CAD and drawings for a one-business-day first response when the RFQ package is complete. We review magnetic assembly, actuator-adjacent, complex CNC interface, and prototype-to-pilot risks before quote direction and partner-route planning.
Typical 5-9 working day CNC sample timing applies only when the CNC route is qualified after scope, material, inspection, partner route, and schedule review. Assembly and pilot support are scoped separately after prototype assumptions are clear.
