Meaning
Conductive interconnect hardware bridges electrical paths between a component and a printed circuit board using compressible columns of polymer filled with metal particles. An elastomeric socket provides a solderless interface that allows high density testing or rapid replacement of land grid array modules. Contact occurs when the module is clamped against the elastomer, compressing the internal conductive filaments until they complete the circuit.
This mechanism avoids the parasitics common in spring loaded pogo pins while maintaining a low profile.
Compression Force
Mechanical pressure applied by a retention lid ensures consistent electrical contact across the entire array. Because an elastomeric socket relies on physical deformation of the polymer matrix, the clamping force must be high enough to break through surface oxides without crushing the substrate.
Frequency Response
Electrical performance remains stable at millimeter wave frequencies due to the short signal path. The elastomeric socket exhibits low signal loss compared to traditional mechanical connectors, making it suitable for 5G radio integration and high speed data validation.
Thermal Boundary
Operational temperature limits are determined by the glass transition point of the base silicone. If a system runs too hot, the elastomeric socket loses its elastic recovery and fails to maintain contact during cooling cycles.
