Description

Technical Field

[0001] The utility model relates to the technical field of gold bonding wire production, in particular to a continuous casting furnace for gold bonding wire processing. Background Art

[0002] Gold bonding wire, also known as ball bonding gold wire, is a basic raw material used in traditional packaging processes such as semiconductor integrated circuits, discrete devices, sensors, optoelectronics, etc. When the gold bonding wire is produced and processed, it needs to be heated and processed by a continuous casting furnace to achieve a softening and mixing effect on the gold bonding wire.

[0003] A Chinese patent discloses a continuous casting furnace for gold bonding wire processing (authorization announcement number CN214023380U). The patented technology mainly uses a nozzle to spray coolant on the gold bonding wire guided out of the wire guide nozzle to cool it, so that the gold bonding wire is quickly cooled and formed after being guided out of the wire guide nozzle. The coolant carried on the gold bonding wire can be wiped by the wiping block to ensure the cleanliness of the gold bonding wire. However, after the coolant continuously cools the gold bonding wire, the coolant itself rises in temperature through heat exchange, resulting in a high wire temperature of the gold bonding wire later, and the cooling line of the gold bonding wire is short. The use of a spraying method is easy to produce a direct impact on the gold bonding wire, resulting in excessive local tension when the gold bonding wire is not completely cooled, and the gold bonding wire is prone to the risk of breaking. At the same time, after the gold bonding wire contacts the wiping block, as the gold bonding wire moves, the friction generated by the two is easy to cause changes in the outer surface of the gold bonding wire. Therefore, we propose a continuous casting furnace for gold bonding wire processing to solve the above problems. Utility Model Content
