Product Spotlight: Aavid Thermalloy Max Clips

What is a Max Clip?

Aavid Thermalloy Max Clips reduce thermal resistance by applying pressure to the center of a semiconductor and forming a connection between the semiconductor and the heat sink. Max Clips provide an effective and easy alternative to screws and rivets and bypass the need for mounting holes. In fact Max Clips maintain constant assembly force despite thermal cycling and interface material compression – this means consistent thermal performance over the life of the product which results in maximum component reliability.

Max Clips vs. Traditional Clips

Factors to Consider When Selecting a Max Clip

Thermal Performance

The thermal resistance of interface materials is inversely proportional to the clip force; the higher the clip force, the better the performance. However, high clip forces are not always necessary. For example, low fore clips are sufficient in applications using thermal grease or phase change materials because those materials ‘wet’ the surface under low pressure. High force clips may be necessary when using a silicone based insulator to achieve adequate performance.


The clip should contact the center of the device to ensure pressure is distributed evenly across the interface, therefore the length of the clip determines the mounting location. The standard length clip is designed to fit most applications. Aavid also offers short and long clip options which will allow the device to be mounted higher or lower on the heat sink if needed.

Product Spotlight: Aavid Thermalloy E-Series Heat Sinks

E-Series BGA Clip Mount Heat Sinks

Aavid Thermalloy prides itself on offering the broadest line of innovative heat sinks to support even the most challenging applications. Aavid’s line of E-Series heat sinks is no exception. Like other heat sinks Aavid’s E-Series heat sinks spread heat over a wide surface area to dissipate it and keep temperatures steady within the application.

The E-Series heat sinks are specifically designed for use with ball grid arrays (BGAs) and feature easy clip-in mounting.  The E-Series’ clip mounting hardware utilizes a plastic frame along with flexible wire springs resulting in easy installation. Aside from ease of installation, Aavid’s E-Series BGA heat sinks offer many other benefits.

E-Series Features and Benefits:

  • 5mm keep out zone for high density PCB layout
  • No short-circuit concern from UL94V-0 rated PA66
  • Re-workable shock and vibration tested
  • Cost effective

What is a Heat Sink?

Ever wonder why your electronic devices don’t overheat? One of the primary reasons is heat sinks. Heat sinks work by spreading heat over wider area, allowing it to dissipate more quickly. All heat sinks are composed of bases and fins which can be fabricated in different shapes depending on the application requirements. The larger the protruding fins the greater the surface area from which heat can dissipate.

A heat sink’s performance depends on several factors including material, protrusion design (the shape and height of the fins), and surface treatment. When heat sinks are utilized without fans they are referred to as passive heat sinks. If fans and heat sinks are used in combination then the heat sinks are called active heat sinks. Heat sinks are typically categorized by the manufacturing method and function. Heat sinks are most commonly used in computers, but are also found in cell phones, refrigerators and many other electronic devices.
