A bonded gold wire continuous casting furnace

Abstract

The invention discloses a key alloy wire continuous casting furnace. A case is arranged at the bottom end of a continuous casting furnace. The furnace has the beneficial effects that an auxiliary cooling mechanism is arranged at the position, between fixed pulleys, in the case, during use, cooling liquid in a water storage box can be pumped into a water absorbing sponge block in an upper shell cover and a lower shell cover through a water pump, and therefore the key alloy wire can be subjected to further cooling molding; after cooling, through a water removal mechanism, driving is achieved through an electric motor, a transmission mechanism drives a sliding rod to slide in a left and right reciprocating manner, a wiping block on the sliding rod is driven to wipe off cooling liquid attachedto the surface of the key alloy wire, and the problems that when an existing key alloy wire continuous casting furnace is used, the cooling effect is poor, and when the key alloy wire is formed and wound, bonding is prone to appearing are solved. The problem that cooling liquid remains on the surface of the cooled key alloy wire, and the cleanliness of the key alloy wire is easily affected is solved.

Description

technical field [0001] The invention relates to the related field of continuous casting furnaces, in particular to a bonded gold wire continuous casting furnace. Background technique [0002] Bonding gold wire is a gold wire used as a connecting wire in integrated circuits, also known as ball bonding gold wire or lead gold wire. The gold content is ≥99.99%, and the sum of trace elements is <0.01%. There are γ-type, C-type and FA There are three kinds of types, and the latter two are used for high-speed bonding. The bonded gold wire continuous casting furnace is an indispensable equipment for the production of bonded gold wires, which can achieve the effect of softening and mixing. [0003] However, the existing bonding gold wire continuous casting furnace has the following problems: [0004] 1. The existing bonded gold wire continuous casting furnace has a poor cooling and heat dissipation effect during use, which is likely to cause mutual bonding when the bonded gold wi...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing bonded gold wire continuous casting furnace has a poor cooling and heat dissipation effect during use, which is likely to cause mutual bonding when the bonded gold wire is formed and rolled up, and cooling liquid will remain on the surface of the bonded gold wire after cooling, which is easy to affect Cleanliness of bonding gold wire
