Precision-formed beryllium copper and phosphor bronze shielding spring fingers and conductive gaskets. Provide stable electrical contact and shielding continuity between shielding cans and PCB, ensuring overall EMI system protection effectiveness.
Conductivity reaching 95% IACS (International Annealed Copper Standard), ensuring effective electrical connection between shielding can and PCB.
Micrometer-precision spring finger forming ensures tight contact with shielding cans and PCB, maintaining low contact resistance.
Heat-treated beryllium copper springs feature long deflection life (1 million+ cycles) with stable contact force.
Supports straight springs, curved springs, snap-fit springs, and conductive gasket customization.
