FP2 2N Gold Wire for Proven Ultimate Reliability
FP2 BenefitsUltimate reliability wire through slowand uniform inter-metallic growthSuperior elastic modulus provides sweep resistance for long wire span or ultra-fine pitchShort, fine-grain HAZ permits extremelylow loopingExcellent for ultra-fine wire diametersand low-k device compatibility
