Extruded Aluminum Heatsink | Custom CNC Machined Radiator
CNC machined heat sinks find prominence in high-tech industries. Precision matters here. For instance, aerospace components demand exactness. These sinks can dissipate up to 250W of heat, ensuring components remain cool.
A precision CNC machined Heatsink is an ideal choice for smaller production requirements as there are no Non Recurring Engineering charges. CNC machined heatsink provides high precision heatsinks with complex features, contours, cut-outs and through-holes. Combined with a full range of finishing can offer your reliable source for quality, affordable machined heatsinks.
Machined heat sinks are typically made from Aluminum 6061 or Copper C1100 to provide optimal thermal conductivity and heat dissipation, and quick turn prototyping is available.
Use advanced CNC machining techniques to ensure that each heatsink is manufactured according to our customer’s specifications and tolerances. This results in a consistent and reliable product that performs optimally under different operating conditions.
The Benefits of Machined Heat Sinks & Power Heatsinks:
The high performance heat sinks to effectively cool DC-DC power converters and AC-DC power modules deployed in a host of electronics applications. Most high power bricks are packaged in thermally conductive plastic or epoxy cases with integral metal base plates. The high power components within the bricks (i.e., semiconductors, inductors, transformers, etc.) are thermally coupled to these base plates, which in turn can be attached to external high performance heat sinks in order to keep the base plate at or below its maximum operating temperature.
Aluminum stampings are anodized for improved performance in natural convection. If the heat sink is to be mounted to the PCB, then a solderable tab or pin can be attached to the heat sink.
Types of Board Level heat sinks Installation
1. Using thermal tape or epoxy is a common method usually associated with low power devices and, while not the best thermal interface material, serves its purpose.
2.Pushpins are another common attachment method and require two small holes in the PCB. The push pin, which can be made from plastic or metal, uses the energy of a small spring to provide enough force to keep the heat sink in place.
3. Anchors and wire clips can be used as an alternative. The anchors are either soldered to the PCB using two small holes per anchor or can be installed in a routed slot in the PCB. In the case of the slot, the anchor is installed from the back side of the PCB and is held in place buy the compression force in the anchor design. The advantage of the anchors is that their location is much more flexible and can be moved out of the way of traces in the PCB.
4. A wire clip is a small diameter wire that is bent into various shapes that, when deformed, engages with the anchors and applies a force to the heat sink to hold it in place. The actual shape of the wire clips is dependent upon the location of the anchors, the heat sink design, and the amount of force required. Multiple wire clips can be used with a single heat sink in applications where a higher force is required. Wire clips are removable and allow the heat sink to be reused in the case of a reworked device.
