Description

Technical Field

[0001] This application relates to the technical field of die bonders, and in particular to a TO-46 die bonder and its control method. Background Technology

[0002] A die bonder uses adhesive to bond wafers to a designated area on a tray, forming an electrical path. Die bonders in related technologies generally include a wafer feeding device, a wafer moving arm device, a dispensing device, a feeding mechanism, a tray transport device, and a receiving mechanism. The feeding mechanism supplies the tray, the dispensing device dispenses adhesive onto the tray, and then the tray enters the tray transport device. The wafer feeding device carries a blue film, which holds the wafers. The wafer moving arm device moves above the blue film, and the wafer feeding device, including a ejector mechanism, lifts the wafer from the blue film. The wafer moving arm then picks up the wafer and transfers it to the tray on the tray transport device, thus bonding the wafer to the tray. The tray transport device then moves the tray, and the receiving mechanism collects the tray from the transport device.

[0003] For a tray with a TO-46 package socket, it is necessary to simultaneously bond two sizes of wafers onto a single TO-46 package socket. Current die bonders can only bond one size of wafer, making it impossible to bond two sizes of wafers simultaneously onto a single TO-46 package socket. This typically requires two separate die bonders, resulting in low processing efficiency and an inability to meet production demands. Summary of the Invention

[0004] In order to simultaneously bond two types of wafers to a single TO-46 package socket, this application provides a TO-46 die bonder and its control method.

A lifting assembly 62 moves the cylinder 61, aligning the tray inside the cylinder 61 with the support track 53. A pushing assembly 63 pushes the tray from the cylinder 61 onto the support track 53. Then, a fixing assembly 54 fixes the tray, and the tray moving mechanism 51 moves the support frame 52 towards the dispensing device 4.

A control method for a TO-46 die bonder, characterized in that, Using the TO-46 die bonder as described in any one of claims 1-9, the process includes the following steps: S1: The material tray moving mechanism (51) drives the bearing support frame (52) to move, so that the bearing track (53) is close to the material cylinder (61); the lifting component (62) drives the material cylinder (61) to move, so that the material tray in the material cylinder (61) is aligned with the bearing track (53), and the pushing component (63) pushes the material tray in the material cylinder (61) onto the bearing track (53); S2: The fixing component (54) fixes the position of the tray, and then the tray moving mechanism (51) drives the tray to move to the predetermined position, and the dispensing device (4) dispenses glue onto the tray; S3: After dispensing the adhesive onto the tray, multiple wafer moving arm devices (3) transfer wafers of different sizes and specifications from the wafer feeding device (2) to the tray, so that the wafers are bonded to the tray. S4: The fixing component (54) releases the fixing of the tray, the tray moving mechanism (51) drives the bearing rail (53) to move and align with the cylinder (61), and then the pushing mechanism (55) pushes the tray on the bearing rail (53) into the cylinder (61).
