Abstract

The application provides a semiconductor integrated circuit lead frame washing device and relates to the technical field of lead frame production. The semiconductor integrated circuit lead frame washing device is provided with a nozzle main body with a nozzle protective cover. When a water pump is started, water pressure is generated in a pressure cabin. At this time, a nozzle extension rod slides out of the pressure cabin until the nozzle protective cover is attached to the semiconductor integrated circuit lead frame body. At this time, the water source in the pressure cabin reaches the nozzle main body through a one-way valve structure. The nozzle main body sprays the water source obliquely upwards. An arc-shaped suction disc and a water blocking strip are attached to the semiconductor integrated circuit lead frame body to form a water blocking area. At this time, the water source flows along a certain track and finally flows out of the area of a ball main body. The water source forms a backflow in the interior of the nozzle protective cover. The backflow water source continuously flushes the semiconductor integrated circuit lead frame body. The particle debris flushed down flows with the water source to flush the lead frame, which is beneficial to improving the water washing effect of the device.
