When conducting reliability testing of semiconductor devices, there’s a wide range of mechanical, thermal, and electrical challenges. Knowing the options available with a clamshell socket will help address and solve these issues. In addition to the lid being the force delivery system, there are other functions the socket lid can provide.
Clamshell sockets derive their name from the way they open and close like a clam — a simple name for a tool in which so much is done. They are used for hand test, all reliability burn-in test methods, and in some cases, production burn-in. They’re needed because:

Clamshell socket lids can be segmented into basic categories of plastic, metal, and hybrids. Subcategories of these are solid or floating plunger, thermal management, and failure analysis. The type of lid you need for the socket depends completely on the package and the features of this package or device under test (DUT). There’s a big difference in the needs of a thick robust package versus a thin CSP, just as there’s a huge difference in low-power devices versus super hot 400W-800W graphics chips or ASICs. So don’t be in a hurry to explore the options available to you when it comes to the lid types.
The above is a breakdown of clamshell socket lids. There might be a case where some of the types are combined to better meet the specific requirement. By communicating with your socket supplier, they will help with your understanding of the wide range of lid types available.
