Component Specifications

Definition
A precision-molded insulating component designed specifically for ATE (Automated Test Equipment) connectors that prevents electrical leakage, arc formation, and short circuits while maintaining signal integrity in high-frequency testing environments. It serves as the primary dielectric barrier between conductive pins/sockets and external metallic structures, engineered to withstand repeated mating cycles, thermal cycling, and mechanical stress during automated testing operations.
Working Principle
Functions as a dielectric barrier using high-resistance materials to prevent current flow between conductors, while providing mechanical alignment and protection for connector contacts. The housing maintains precise contact spacing to prevent arcing, manages thermal dissipation from test currents, and ensures consistent electrical performance through controlled dielectric constant and surface resistivity.
Materials
High-performance thermoplastics: PEEK (Polyether Ether Ketone) for extreme temperature applications (up to 250°C), PPS (Polyphenylene Sulfide) for chemical resistance, or glass-filled nylon for cost-effective solutions. Material selection based on CTI (Comparative Tracking Index) >600V, UL94 V-0 flammability rating, and dielectric strength >15 kV/mm.
Technical Parameters
  • CTI >600V
  • Water Absorption <0.2%
  • Dielectric Strength >20 kV
  • Flammability Rating UL94 V-0
  • Dimensional Tolerance ±0.05mm
  • Insulation Resistance >10^12 Ω
  • Operating Temperature -40°C to +150°C
Standards
IEC 60664-1, UL 746C, ISO 16750-4
