In the semiconductor industry MOLDING process, the ic lead frame needs to be placed in the hanging basket for molding. At this time, there is a problem that the frame lead frame inside needs to be counted. The number of points in the traditional ones is very slow. At this time, in order to improve the work efficiency, it is necessary to use the aluminum alloy inspection to check. As long as one pair can immediately know the storage quantity of the chip frame lead frame, effectively improve the work efficiency, and save the enterprise. 10% of the cost.
