Socket Body: Flammability Rating UL94 V-0

Component Specifications

Definition

The socket body is the foundational housing component in a test socket assembly, designed to precisely position and secure the device under test (DUT) while maintaining electrical isolation and thermal management. It interfaces with the socket's contact elements and mounting hardware to ensure reliable performance during automated testing of integrated circuits, semiconductors, or other electronic components.

Working Principle

The socket body operates by providing a rigid, dimensionally stable platform that aligns the DUT with the test system's contact pins or probes. It ensures consistent mechanical positioning to maintain electrical connectivity and signal integrity during test cycles, while often incorporating features for heat dissipation and protection against environmental factors.

Materials

High-performance engineering plastics (e.g., PEEK, LCP, PEI) or ceramics for electrical insulation and thermal stability; sometimes aluminum alloys for enhanced heat dissipation. Material selection depends on required dielectric strength, operating temperature range, and mechanical durability.
