- Thermal design inputs
- Provide heat-source/contact geometry and the OEM's required thermal resistance and pressure-drop criteria.
- Channels and base
- Define channel geometry, base thickness, mounting, flatness and surface requirements.
- Material and joining
- Specify wrought-copper grade, joining process, coating and accepted manufacturing routes; no automatic cast-grade substitution.
- Coolant compatibility
- Identify the coolant, full wetted-material list and corrosion/compatibility validation responsibilities.
- Cleanliness and sealing
- Define particles, residues, leak-test criteria, cleaning verification and protective packaging.
- Feasibility boundary
- Identify which design, machining, joining and performance tests need a qualified supplier before assessing a proposal.
