||"The ultimate goals of any thermal testing operation are efficiency, accuracy, and stability," writes Exatron's David Brehmer in his article "A Road Map to Successful Thermal Testing." There are many variations in methods of thermal testing, but the common denominator across the board is the socket.
Many sockets are made of low-cost materials, such as plastic, which acts as a thermal insulator. Spring probes can also behave like mini heatsinks, resulting in temperature loss during testing, an inability to achieve the hottest and coldest temperatures, and long soak times between insertions.
Brehmer outlines Exatron's Copperhead socket and Wide Range Thermal Head (WRTH) as a better approach to thermal testing. The Copperhead's socket topper replaces thermally-insulating plastic with thermally-conductive copper, allowing for much more efficient heat transfer and better temperature stability during testing. The company also offers versatile workstations that can easily be customized for applications that range from low- to high-volume.
