Q1: How thin can you make the fins for a small aluminum radiator via extrusion?

A1: Extruding ultra-thin micro fins requires high-precision tooling control. Depending on the complete profile geometry and fin height, we can reliably extrude fine fin structures with thicknesses down to approximately 0.8mm to 1.0mm to maximize cooling capabilities in compact envelopes.

Q2: Does black anodizing significantly improve the performance of a miniature passive heat sink?

A2: Yes, absolutely. For small radiators operating without forced fan ventilation (passive cooling), thermal radiation accounts for a large percentage of overall heat transfer. Black anodizing significantly raises the surface emissivity, allowing the tiny radiator to radiate heat far more efficiently into stagnant air spaces.

Q3: Can you supply these micro radiators pre-applied with double-sided thermal conductive tape?

A3: Yes, we provide full value-added assembly processing. We can deliver small radiators cut to precision lengths with high-performance thermal conductive interface tape pre-applied to the flat base, allowing your manufacturing line to quickly peel and mount them onto electronic components.

Q4: What is your capability regarding base flatness for precision microelectronics?

A4: To reduce interfacial thermal resistance, microscopic contact gaps must be minimized. We use high-speed CNC precision milling and diamond fly-cutting to face-mill the contact base of our miniature heat sinks, achieving an exceptionally flat finish that ensures maximum surface contact with your electronic dies.
