What is a Skived Heat Sink
GALLOP INNOTEK skived heat sink is achieved through a special scraping process. It uses precisely designed blades to perform multiple precise cuts on fixed metal substrates such as copper and aluminum. Each cut pushes the metal upwards and shapes it into a continuous thin fin. This thin and dense fin, integrated with the base, serves as the cutting heat sink.

Features and Advantages of Skived Heat Sinks
One-piece Formed Structure: The heat dissipation fins and base of the GALLOP INNOTEK skived heat sink are machined from the same metal blank, forming a complete whole. This completely eliminates the contact thermal resistance existing in traditional welding processes. The heat conduction path from the base to the top of the fins is extremely smooth, characterized by extremely low thermal resistance and rapid heat dissipation.
Thin and High-density Fins: GALLOP INNOTEK skived heat sinks can produce fins with a thickness of only 0.1 millimeters and a height-to-thickness ratio exceeding 20:1, which is unachievable by traditional extrusion processes. Moreover, due to the extremely thin fins, a greater number of fins with smaller spacings can be arranged per unit area, which maximizes the heat dissipation surface area. It can also provide your product with the maximum heat dissipation effect.
High Heat Dissipation Performance: GALLOP INNOTEK skived heat sinks, with their extremely high fin density and large heat dissipation surface area, can help your products dissipate more heat, making them particularly suitable for cooling chips with high heat flux density in compact Spaces.
Flexible Design: Through programmed control of tool paths, GALLOP INNOTEK skived heat sinks can be machined into wave-like or fish-scale patterns. This design can effectively disrupt the boundary layer of airflow to increase turbulence and improve heat dissipation efficiency, a feature that is also unachievable with traditional extrusion processes. processes.
GALLOP INNOTEK skived heat sinks have the above significant advantages, maximizing heat dissipation efficiency and power density, and have become an irreplaceable key heat dissipation solution. If you also require a heat sink, please do not hesitate to contact GALLOP INNOTEK at your convenience.

Material for Skived Heat Sinks
Copper
Copper is the top material for GALLOP INNOTEK skived heat sinks. If you are pursuing the ultimate heat dissipation capacity, copper is your first choice. Its thermal conductivity is almost twice that of aluminium, and it can conduct heat from the chip contact surface to the end of each fin at an extremely fast speed, with an extremely high heat dissipation efficiency. In addition, copper has a greater specific heat capacity than aluminium. It can absorb more heat before starting to warm up, which is very beneficial for handling instantaneous power peaks.
Aluminum
Aluminum is the most widely used material in GALLOP INNOTEK skived heat sinks, providing the optimal balance between performance, weight, and cost. If you are seeking cost performance, aluminum material is the most suitable choice for you. Aluminum has a low density and is relatively lightweight. Moreover, its raw material prices are low, making it easy to produce on a large scale, and the overall cost is much lower than that of copper. Additionally, it exhibits excellent corrosion resistance and can naturally form an aluminum oxide protective film on its surface.
Comparison of Skived Heat Sinks and Traditional Processes
Structure and Performance
GALLOP INNOTEK skived heat sinks feature an integrated monolithic structure where fins and base are machined from a single metal block. There is no problem with contact thermal resistance, and the heat conduction efficiency is high.
While traditional extrusion processes also produce monolithic structures, their fin height-to-thickness ratios are relatively low. The traditional welding process has interface and solder thermal resistance, resulting in a bottleneck in thermal conductivity.
Design Form
GALLOP INNOTEK skived heat sinks can manufacture ultra-thin, extremely high, and extremely dense fins, and can achieve three-dimensional designs such as wavy shapes, which maximize the heat dissipation area and heat dissipation efficiency.
The fins produced by the traditional extrusion process have a single shape, are thick, and sparsely distributed. Although the traditional welding process can achieve high fins, its design flexibility is still inferior to that of skived heat sinks.
Cost and Application
The manufacturing cost of GALLOP INNOTEK skived heat sinks is high because of their slow processing and large amount of waste. It is generally dedicated to extremely high heat density scenarios such as servers, 5G communications, and AI computing.
In comparison, the traditional extrusion process is relatively cost-effective and remains the mainstream choice for the vast majority of scenarios, including ordinary electronics and personal computers.
If you are pursuing heat dissipation performance, GALLOP INNOTEK skived heat sinks are your ideal choice. However, if you prioritize cost performance, traditional craftsmanship may be more suitable for you.
