Skived vs Bonded-Fin vs Heat-Pipe Copper Heat Sinks

These are three common ways to build a copper heat sink. Skived copper heat sinks are our core product, made in our own factory in Dongguan, China; bonded-fin and heat-pipe designs are available on request. This guide explains how each is built and what to send for a quote.

How each one is built

Type How it is built What we offer
Skived Fins are cut from a single block of oxygen-free copper (C1100 / TU1), so fins and base are one piece Core product · MOQ 1,000 pcs · best pricing at 5,000+
Bonded-fin Separate fins are fixed into grooves in a machined base Available on request
Heat-pipe Sealed heat pipes carry heat from the heat source to a fin stack placed elsewhere Available on request

When a skived heat sink fits

  • The heat source sits directly under the heat sink
  • You want fins and base in one piece, with no joint between them
  • Fin height, thickness and pitch fit within one copper block, to your drawing
  • You need 1,000 pcs or more per design

Skived Copper Heat Sinks

When to ask about bonded-fin

  • Your design needs fins taller or larger than one skived block allows
  • You want to discuss a different fin material or fin layout on a copper base

Bonded-Fin Copper Heat Sinks

When to ask about heat-pipe

  • The heat source and the space for fins are in different places
  • Heat has to be spread across a larger fin area than the base can reach

For bonded-fin and heat-pipe designs, send your drawing and thermal requirements and we will confirm feasibility, MOQ and lead time in your quote.
