Abstract

The invention discloses a treatment production line of a lead frame. The treatment production line of the lead frame comprises a material taking mechanism, a lead frame treatment groove, a lead frame jig, lead frame pushing equipment and a water jet cutter, wherein a material pushing device of the material taking mechanism is driven by a first driving device and can realize automatic working; an immobilizing mechanism of the lead frame treatment groove is used for maintaining a semiconductor lead frame at a vertical position, so that the semiconductor lead frame is small in occupied space and long in soaking time, and a better soaking effect is obtained; a liquid receiving groove formed in the lead frame jig can be used for completely receiving a chemical treatment solution dripping from the lead frame, so that the phenomenon that since the chemical treatment solution drips on structures such as an air cylinder and guide rails, the corrosion is caused is avoided.

Description

technical field [0001] The invention relates to lead frame processing equipment in the semiconductor field, in particular to a lead frame processing production line. Background technique [0002] In the field of integrated circuits, it is generally necessary to use a lead frame as a carrier for integrated circuit chips. The lead frame uses bonding materials such as gold wire, aluminum wire, and copper wire to realize the electrical connection between the lead-out end of the chip's internal circuit and the external lead, forming a key structural part of the electrical circuit, which acts as a bridge connecting the external wire. Due to the high-precision production requirements of integrated chips, the lead frame needs to be smooth without burrs. Therefore, chemical soaking is generally required to facilitate further processing. The processing equipment for the lead frame in the prior art is generally inefficient, and the operation settings are not very reasonable. Conten...
