The manufacturing of PC water block copper skived heat sinks involves several key steps.
Firstly, What's the material can be seleted for the high density skived sinks for the micro-channel water blocks?
high - purity oxygen - free copper raw materials, The copper is cut into appropriate - sized block blanks to serve as the starting material.
Next, CNC milling machines are employed for rough machining.
This step removes a large amount of excess material, shaping the basic structure of the water block, including the main body and mounting features, while leaving some allowance for subsequent precise processing.
The most crucial step is the skiving process.
Using high - precision skiving machines, extremely thin and elongated fins are cut from the copper block surface. The cutting thickness is minimal, creating a large number of closely - spaced fins with consistent thickness and spacing, which significantly increases the surface area for heat dissipation.
What are the surface treatment for the skived heat sink for the water block?
Polishing is applied to reduce surface roughness, minimizing water flow resistance. Additionally, a coating such as nickel plating is added to prevent oxidation and enhance corrosion resistance.
