Description

Technical Field

[0001] The invention relates to the technical field of bonding wire annealing, in particular to processing equipment and a processing technology of a copper-based surface palladium-plated bonding wire. Background Art

[0002] ‌Copper-based palladium-plated bonding wire is a high-performance bonding material, mainly used in semiconductor packaging and other fields. Its outer surface is plated with a layer of palladium to improve oxidation resistance and bonding performance. It includes the preparation of the copper wire substrate, the formation of the palladium plating layer, etc. The preparation process of the copper wire substrate mainly includes vacuum melting, pulling down the rod, wire drawing, copper wire annealing, etc.

[0003] However, when the existing copper-based surface palladium-plated bonding wire processing equipment and its processing technology are used, when the copper wire is annealed, the copper wire needs to be heated, kept warm and cooled in three stages.

[0014] A process for processing a copper-based surface palladium-plated bonding wire, using the above-mentioned copper-based surface palladium-plated bonding wire processing equipment, comprises the following steps: S1: When heat treating the bonding wire, protective gas is introduced into the heating box through the gas supply valve, and then the bonding wire is passed into the rotating tube through the feed port, and the bonding wire is between the two rubber rollers. At this time, under the action of the third spring, the two rubber rollers are sealed against each other. At the same time, under the sealing operation of the moving plate, the sealing of the feed port and the discharge port can be ensured, thereby avoiding the escape of protective gas and heat, being more energy-saving and environmentally friendly, and ensuring the efficiency and effect of heating. In addition, when heating, the motor is started, and the rotation of the motor drives the rotation of the rotating shaft, thereby driving the rotation of the rubber roller, and then driving the conveying of the bonding wire; S2: At the same time, the electric heating plate is started for heating, and the fan is started so that the hot air in the heating box enters the connecting pipe through the exhaust pipe, and blows on the surface of the bonding wire after passing through the fan and the blowing pipe, so that the bonding wire can be preheated before entering the rotating tube, which can improve the heating efficiency and effect.

At the same time, the electric heating plate is started for heating, and the fan is started so that the hot air in the heating box passes through the exhaust pipe into the connecting pipe, and then passes through the fan and the air blowing pipe and blows onto the surface of the bonding wire, so that the bonding wire can be preheated before entering the rotating tube, which can improve the heating efficiency and effect. The heated bonding wire can be kept warm in the rotating tube, and after being kept warm, it can enter the cooling box through the discharge port for cooling.

[0016] (2) The processing equipment and processing technology of the copper-based surface palladium-plated bonding wire are provided with a driving mechanism and a first pushing mechanism, etc. When heating is performed, when the hot air enters the fixed box through the blowing pipe, it can impact the surface of the baffle plate, causing the rotating rod to rotate. When the rotating rod rotates, it drives the gear to rotate, thereby driving the gear ring and the rotating tube to rotate, and then driving the movable plate and the electric heating plate to rotate, so that the heating is more uniform and the heating efficiency and quality are guaranteed. In addition, the movable rod and the second pushing block are driven downward by the lifting module. When the second inclined surface abuts against the side wall of the movable ring, the movable ring can be pushed to move in the direction away from the second connecting block. At the same time, the second spring is stretched. When the movable ring moves, it drives the first pushing block to move synchronously. When the first inclined surface abuts against the end of the pushing rod, multiple movable plates can be pushed to move closer to each other. At the same time, the first spring is compressed, so that it is easy to adjust and control the heating distance of the electric heating plate to the bonding wire, which can improve the heating efficiency and effect.

[0017] (3) The processing equipment and processing technology of the copper-based surface palladium-plated bonding wire are provided with a reset component and a driving mechanism. When heating is performed, the bonding wire is placed between two rubber rollers. At this time, under the action of a third spring, the two rubber rollers are sealed against each other.

At this time, under the action of the third spring (803), the two rubber rollers (16) are sealed against each other. At the same time, under the sealing operation of the movable plate (17), the sealing of the feed port (13) and the discharge port (14) can be ensured, thereby preventing the shielding gas and heat from escaping. In addition, when heating is performed, the motor (903) is started, and the rotation of the motor (903) drives the rotation of the rotating shaft (902), thereby driving the rotation of the rubber roller (16), and further driving the conveying of the bonding wire; S2: At the same time, the electric heating plate (18) is started for heating, and the fan (1901) is started, so that the hot air in the heating box (10) enters the connecting pipe (1902) through the exhaust pipe (1904), and blows onto the surface of the bonding wire after passing through the fan (1901) and the blowing pipe (1903), so that the bonding wire can be preheated before entering the rotating tube (12). The heated bonding wire can be kept warm in the rotating tube (12), and after being kept warm, it enters the cooling box (20) through the discharge port (14) for cooling; S3: When heating is performed, when hot air enters the fixed box (701) through the air blowing pipe (1903), it can impact the surface of the baffle (703), causing the rotating rod (702) to rotate. When the rotating rod (702) rotates, it drives the gear (602) to rotate, thereby driving the ring gear (601) and the rotating tube (12) to rotate, and further driving the movable plate (17) and the electric heating plate (18) to rotate; S4: Furthermore, the lifting module (501) drives the moving rod (502) and the second pushing block (503) to move downward. When the second inclined surface (504) abuts against the side wall of the moving ring (301), the moving ring (301) can be pushed to move in a direction away from the second connecting block (403). At the same time, the second spring (404) is stretched. When the moving ring (301) moves, the first pushing block (303) is driven to move synchronously. When the first inclined surface (304) abuts against the end of the pushing rod (302), the plurality of moving plates (17) can be pushed to move closer to each other. At the same time, the first spring (203) is compressed, thereby facilitating the adjustment and control of the heating distance of the electric heating plate (18) on the bonding wire.
