[0002] Integrated circuits manufactured on the surface of semiconductor chips are also called thin-film integrated circuits. Another type of thick-film integrated circuit (hybrid integrated circuit) is a miniaturized circuit composed of independent semiconductor devices and passive components integrated into a substrate or circuit board. The chips need to be inspected and sorted during the production process. Use an air knife to blow away the defective products.
[0003] The existing air knife blowing mechanism used for chip detection and sorting still has some defects. Most of them lack stability when fixing the air pipe and are directly connected by threads. After a long time of use, they are easy to loosen and leak, resulting in the air knife being unable to be used normally. For this reason, we propose an air knife blowing mechanism for chip detection and sorting. Utility Model Content
