Physical Foaming vs Solid Extrusion for High-Speed Twinax Cables
Physical foaming and solid extrusion are two common insulation extrusion processes for high-speed twinax cables, but they are designed for different performance requirements. Physical foaming extrusion is usually preferred for low-loss, high-frequency signal integrity cable because it can reduce dielectric constant, capacitance and insertion loss. Solid extrusion is simpler, more stable and suitable for standard cable […]
Physical Foaming vs Solid Extrusion for High-Speed Twinax Cables
For manufacturers producing foamed dielectric twinax cable, the choice between physical foaming extrusion and solid extrusion directly affects cable loss, impedance stability, capacitance, outer diameter, production efficiency, and final product positioning.
