Product Description
Stamped copper heat sinks are precision-made and structurally interlocked from integrated copper sheets. The densely arranged fins with cutouts facilitate the installation of other components. High-purity copper delivers outstanding thermal conductivity, and the interlocking structure reduces interfacial thermal resistance, making them ideal for compact air cooling of computing modules and RF components.
Product Features
Interlocked Stamped Copper Integrated Structure
Whole radiator formed by precision stamped copper sheets with mechanical interlock, no glue or loose assembly gaps, stable overall structural rigidity.
01
Dense Parallel Copper Fin Layout
Ultra-thin closely spaced copper fins expand heat exchange area greatly, boosting natural convection passive cooling efficiency.
02
Custom Pre-Cut Component Cutouts
Reserved rectangular cutouts on fin panels for PCB connectors, power chips and wiring routing, eliminate secondary cutting during equipment assembly.
03
High-Purity Copper Raw Material
Adopt oxygen-free copper with top-tier thermal conductivity, far superior heat transfer performance compared to standard aluminum heat sinks.
04
Built-In Mounting Lugs
Integrated stamped positioning tabs on base edge for fast screw fixation to motherboards, cabinets and heat source substrates.

Advantages
Industry-Leading Thermal Conductivity
High purity copper thermal conductivity is nearly twice that of aluminum, rapidly extract concentrated heat from high-power chips to avoid overheating.
Ultra-Low Interfacial Thermal Resistance
Mechanical interlock tightly combines all copper fins as one solid unit, no loose contact gaps; heat transfer loss far lower than welded/glued split heat sinks.
Ultra-Compact Thin Flat Profile
Thin stamped copper sheet design saves vertical installation space, ideal for slim miniaturized electronic equipment with limited internal clearance.
Pre-Designed Cutouts Reduce Assembly Work
Pre-reserved cutouts on fins skip on-site cutting process, shorten customer product assembly time and lower processing waste cost.
Light & Rigid Integrated Body
Stamped interlock structure delivers stable shock resistance, thinner weight than solid copper block radiators without sacrificing cooling performance.
Long Service Anti-Oxidation Option
Optional nickel/tin plating surface treatment prevents copper oxidation discoloration, stable performance for long-term continuous operation devices.
Applications
Computing Hardware
Mini ITX motherboards, server memory modules, embedded computing chips, SSD cooling radiatorss.
RF & Communication Equipment
RF power amplifiers, signal transceivers, base station small power modules, 5G communication components.
