What materials suit high-power heat sinks?
Copper alloys offer superior conductivity; aluminum suits weight-sensitive designs; composites (CuMo) work for extreme thermal stability requirements.
How do you confirm fin geometry and base flatness?
We use CMM probes and optical checks to measure fin pitch, height, and base flatness, ensuring compliance with thermal interface specifications.
Can custom heat sinks be produced under NDA?
Yes, all designs, performance data, and production files are protected under strict nondisclosure agreements and controlled access.
What finishes prevent corrosion and oxidation?
Anodizing for aluminum and nickel/tin plating for copper prevent oxidation and maintain low thermal contact resistance over time.
What precision tolerances are achievable on heat sinks?
Fin geometry can be held to ±0.01 mm; base flatness to ±0.005 mm with lapping or precision machining when required.
How reliable is your manufacturing and delivery for production runs?
ISO-aligned workflows, SPC, and in-process CMM validation support consistent quality and a documented 98% on-time delivery rate.
