Copper Bonding Wire

• YC1: 4N high-purity copper wire – low hardness with excellent ball-forming capability.
• YC2: 3N flexible copper wire – good corrosion resistance.
• YC3: 2N alloyed copper wire – strong fatigue resistance with higher reliability.
• YC4: 1N5 alloyed copper wire – excellent oxidation resistance and high reliability.
