High Performance Heat Sink with Secure Attachment System

Advanced Thermal Solutions is providing maxiFLOW™ heat sinks with superGRIP™ heat sink attachment systems for cooling BGAs and other components in the restricted airflow conditions where secure attachment is needed for reliable performance.

Norwood, MA, March 24, 2012 --(PR.com)-- maxiFLOW™ heat sinks from ATS feature a low profile, spread fin array that maximizes surface area for more effective convection (air) cooling. The ATS superGRIP™ system is a unique method for mounting the maxiFLOW sinks quickly and securely onto a wide range of hot running BGA components, while using minimal space on a PCB and requiring no holes to be drilled into the board.

maxiFLOW heat sinks have a low profile, spread fin architecture to maximize surface area for more effective convection (air) cooling. Testing at an air flow rate of just 0.5 m/s (100 ft/m) shows that device junction temperatures (Tj) can be reduced by more than 20 percent below the temperatures achieved using heat sinks with traditional fin styles.

The two-part superGRIP attachment system features a plastic frame clip that fastens securely around the perimeter of a component, and a metal spring clip that slips through a heat sink’s fin field and locks securely to both ends of the plastic frame. The resulting superGRIP assembly applies steady, firm pressure to the component throughout the product lifecycle, improving thermal performance and long-term reliability.

The pressure strength and security of the superGRIP heat sink attachment system permits the use of high performance phase-changing thermal interface materials (PCMs) that improve heat transfer by as much as 20 times over typical double-sided adhesive thermal tapes. The superGRIP design allows the heat sink to be detached and reattached without damaging the component or the PCB, an important feature for applications where PCB rework and ease of assembly and disassembly are important.
