As an important raw material, gold wire must possess several important characteristics, such as good mechanical and electrical properties, appropriate destructive power, selecting the correct size, and a clean, pollution-free surface. currentlyLEDThe diameter of gold wire in the packaging industry is mostly chosen1.0MILor1.2MILThe purity is99.99%The elongation rate is generally2%~8%The general requirements for fracture load are:1.0MILGold wire is greater than10g，1.2MILGold wire is greater than16g.

Too soft gold wire can lead to1.loopHanging arch wire2.Spherical instability3.The neck of the ball is prone to contraction4.Gold wire is prone to breakage

Gold wire that is too hard can cause1.Drill holes in the chip electrodes or epitaxial layers2.Golden Ball Neck Fracture3.Difficulty in forming alloys4.loopThe control of the arch wire arc is difficult. Therefore, it is extremely important to determine whether the gold wire meets the composite requirements.
