Component Specifications

Definition
The Actuator/Lid is a critical component in test socket assemblies used for semiconductor device testing. It consists of a mechanical actuator mechanism and a protective lid that work together to open and close the socket interface. This component ensures precise alignment between the device under test (DUT) and the test system's contact pins while protecting sensitive components from contamination and mechanical damage during handling and testing cycles.
Working Principle
The actuator mechanism uses pneumatic, hydraulic, or electromechanical force to move the lid between open and closed positions. When activated, the actuator retracts the lid to allow device insertion/removal, then closes it to maintain proper contact pressure and environmental sealing during testing. Position sensors typically provide feedback to ensure correct operation.
Materials
Aluminum alloy (e.g., 6061-T6) for structural components, stainless steel (e.g., 304 or 316) for moving parts, PEEK or Ultem for insulating elements, and silicone or fluorocarbon rubber for sealing gaskets.
