       Especially in the marking process of integrated circuits, due to the different industries and functions used by different integrated circuits, they are basically designed according to specific actual needs, which makes different integrated circuits must have marking information that can be used to distinguish. However, the use of traditional information labeling methods, due to the high level of integration of integrated circuits, small size, and complex internal components, it is easy to cause damage to integrated circuits and unsatisfactory marking effects, and some are even difficult to mark. But take advantage of the current one
