The Thought Process Behind Cooling Source BGA Heat Sinks

The aim of designing heatsinks is twofold. The heatsinks need to provide thermal conduction inside and thermal convection on the surface. Evolutionary methods have optimized heatsinks for specific tasks that make efficient use of material and energy.

Nature is a source of inspiration when developing new products. Think about the branched systems of leaf venation and human blood circulation. Both systems take in and transport matter while conserving materials and structural stability. Designs vary based on effects in the environment.

Many successful heat sink designs are based on the same principle. They transport and dissipate heat energy. The result is an efficient solution for the required task. Shapes and processes are in harmonic balance. The technical function of heat dissipation connects intrinsic design of the device for which it is used.

Cooling Source offers a wide selection of BGA heat sinks. Our specialty is providing mechanical attach solutions where heatsinks are connected to the chip without holes or adhesives in the printed circuit board (PCB). The attachment solutions are used for high-reliability applications.

Customers choose Cooling Source when they need reliable, cost-effective cooling solutions. Our BGA heatsinks are made from high-conductivity aluminum. They handle the most demanding applications. We have a variety of attachment options, shapes, and sizes from which to choose.

If a standard option does not meet the customer's needs, we have a custom design service that will. Some of the BGA heat sinks we carry include:

 Elliptical Fin BGA Heat Sinks

 Pin Fin BGA Heat Sinks

Straight Fin BGA Heat Sinks

 Elliptical Fin Heatsinks

Elliptical fin heatsinks are aluminum BGA heat sinks that are highly efficient cooling devices ideal for environments with linear airflow. They are an improvement on cross cut heatsinks that were simply plated fin heatsinks with extra cuts across the fin length. The aerodynamic fins of the elliptical shape make airflow efficiency easier. They are ideal when airflow is limited.

Pin Fin Heatsinks

Cooling Source offers pin fin heatsinks that are well-suited for applications where airflow comes from the top. Precision forged pin fin heatsinks come in passive and active versions. The pin fin heatsinks can be forged of copper or aluminum.

Straight Fin Heatsinks

These heatsinks have many base dimensions and heights up to 15 mm They are ultra-performance heatsinks that have a high aspect ratio. The design of the straight fin heatsinks is optimal for applications with adequate airflow. They offer excellent cooling solutions for PCB layouts that are spatially constrained.

The high-performance ensures a reliable life of the product at a cost lower than other extruded heatsinks. The extruded aluminum keeps costs down, reduces weight, and minimizes thermal resistance. Cooling Source has or makes all of these heatsinks and more. Call us at 925-292-1293.
