Technical details and manufacturing context for Socket Adapter Plate/Interface Board

Definition
The Socket Adapter Plate/Interface Board is a critical component within a Test Site with Socket system. It serves as the physical and electrical intermediary between the standardized test socket (which holds the device under test, or DUT) and the specific mounting points, alignment features, and signal/power routing channels of the larger test site or handler platform. It ensures precise mechanical alignment, reliable electrical contact, and proper signal integrity for automated testing.
Working Principle
The adapter plate is mounted to the test site. The test socket is then mounted onto this plate. The plate contains precision-machined features (pins, guides, holes) to ensure the socket is aligned correctly. Internally, it may contain conductive traces, vias, or embedded wiring that routes electrical signals from the socket's contact pins to the corresponding connectors or probes on the test site's main interface. Its primary function is to translate the socket's footprint and pinout to match the test site's requirements.
Common Materials
Fiberglass-reinforced epoxy laminate (e.g., FR-4), Aluminum alloy
