Extruded aluminum is one of the most popular and cost-efficient heat sink fabrication methods. Boyd Corporation produces a wide variety of Standard Extruded Heat Sink options for quick solutions optimized for board level devices like TO packages, BGA/FPGA devices, and even CPUs & GPUs. These standard heat sinks are available with different mounting methods and some come with pre-applied thermal interface materials to streamline assembly into your PCB.

Standard Extruded Heat Sinks are pre-cut and finished heat sinks that typically include installation hardware. Standard Extruded Heat Sinks include finished flat back, double sided with gaps, or Max Clip™ extrusions typically meant for board level cooling.

Boyd’s Standard DC/DC Converter heat sinks are designed to cool half, quarter and one-eighth brick sizes as well as the Vicor style footprint. To streamline assembly, each DC/DC Converter heat sink has standard mounting holes and pre-applied thermal interface material.

For applications that require more customization, we utilize our broad extrusion profile library to develop custom and semi-custom air cooled solutions. Boyd extruded heat sink profiles range from simple flat back fin structures to complex geometries for optimized cooling. Alloys 6063 and 6061 are our most commonly featured aluminum alloys for high thermal conductivity.
