Denka ALSINK composite heat spreaders

Denka Company Limited · Material properties and interface engineering

Purpose: Heat-spreader/baseplate selection must consider heat spreading, expansion and bonding surfaces.
Technical approach: ALSINK is an aluminum/ceramic composite with properties adjusted by ceramic type/content and a surface designed for fabrication/plating.
Scope of use: Consider power-module baseplates or package lids with actual dimensions, finishes and assembly conditions defined.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
Do not assume electrical insulation or compliance. Material properties alone do not resolve package warpage or TIM contact.
What to prepare
BLNKK suggests preparing geometry, heat-source, clamping, attachment and TIM details for flatness, contact and thermal-cycle comparisons.
Confirm with the supplier
Confirm composite variant, dimensions, machining/plating, attachment compatibility and actual component property/tolerance documents.
Public evidence: Named Denka and manufacturing-subsidiary bodies document composite construction and baseplate/lid uses.
