Abstract
A surface treatment equipment is designed for forming nickel barriers on a plurality of terminals for preventing solder wicking is disclosed. The surface treatment equipment includes a retractable feeding system, a laser engraving system, an image sensor, and a control system. The retractable feeding system is utilized to transmit a strip that has the terminals. The laser engraving system is utilized to ablate the terminals. The image sensor is utilized to collect a plurality of images of the ablated terminals. The control system receives the images to perform image recognition. When a defective terminal is recognized, the control system controls the retractable feeding system to transmit in reverse and controls the laser engraving system to repeatedly ablate the defective terminal. The defective terminals can be automatically recognized by the image sensor accompanying the control system. Thus, the drawback of a human visual inspection is solved.
