Product details
Board level heat sinks can be stamped or extruded. Stamped heat sinks are
made with sheet metal that has gone through a progressive punching process
where details and features are added with each stamp of metal going through
the punching die.
Stamped heat sink geometries are designed for specific electronic package types
to ensure optimized fit and function on a PCB. These heat sinks can be passive or
active based on the addition of a fan which is typically used to increase air flow
across the entire board or system.Extruded Aluminum is one of the most popular and cost-efficient fabrications.
Extruded heat sinks range in size based on application, smaller for board level
or larger for medium power applications. They can be designed for passive or
active cooling based on fin shape and pitch. Board level extruded heat sinks
are common for packages such as BGAs and FPGAs.Choosing the right extruded heat sink is largely based on the profile needed.
Extruded heats sinks are made by creating a profile die that determines fin density,
pitch, and length, as well as the base height and width. Softened Aluminum is
pushed through the die to create a long bar, known as a raw bar, with the same
profile and size as the die. The bar is then cut into smaller, standard shaped
bars/rectangles or custom lengths. These are further machined and finished to
create customized heat sinks. This process is fast, cost-efficient, and scalable;
which is why many consider extruded heat sinks first when searching for a
solution.
