Description

TECHNICAL FIELD

[0001] The utility model relates to a pipe leg cutter, particularly to an integrated circuit pipe leg cutter. BACKGROUND

[0002] In the production process of integrated circuits, there are mainly three key steps: chip design, chip testing and packaging testing; as the last process, packaging testing is particularly strict in product quality requirements. Packaging forms are various, mainly including plastic packaging, ceramic packaging and metal packaging. Regardless of the packaging mode, the product after packaging is usually a regular rectangle with a frame. In order to ensure that the product can pass the final test smoothly, the excess frame must be removed, which gives rise to the application of integrated circuit leg cutting machine equipment.

[0003] In the cutting process of integrated circuit pipe legs, the initial step is crucial; for different types of integrated circuits, selecting appropriate leg cutting tools is the key to success; in addition, the cutter inside the leg cutting machine must be accurately matched with the leg cutting tool; once there is a positional deviation between the two, the cutter and the tool may collide, causing damage to the cutting edge; such a mistake not only causes the pipe leg to bend or warp, but also may cause the pipe leg to be cut too short, which cannot meet the customer's specification requirements, and finally causes the product to be scrapped.
