Abstract
Description
Technical Field
[0001] This application belongs to the field of die bonding equipment technology, and more specifically, relates to a substrate transport module and a die bonding machine. Background Technology
[0002] Die bonding typically involves using a die bonding arm to pick up a wafer from its feed position and move it to a die bonding position on the substrate, precisely mounting the wafer onto the substrate. The wafer is usually mounted in a die ring, which supports it. After the wafer is removed from the wafer, an empty die ring is formed. For ease of description, the die ring containing the wafer is called a full die ring. The wafer has a front and a back side. The back side of the wafer typically has electrodes for connection to the substrate, while the front side of the wafer is attached to a blue film. The substrate is typically a PCB (Printed Circuit Board).
[0003] A Chinese invention patent application with application number 202110522689.4 discloses a die bonding device, including a frame, a die feeding assembly, and a die transfer assembly. The die feeding assembly can transfer die holders to the die transfer assembly, and the die transfer assembly can transfer die holders to the die bonding position. The device also includes a unloading assembly for receiving die holders transferred from the die transfer assembly and transferring them to the next station. The unloading assembly is mounted on the frame and connected to the die transfer assembly. In the die feeding assembly, a feeding motor drives a corresponding drive wheel to rotate, which in turn drives two conveyor belts to rotate synchronously, thereby transferring the die holders to the die transfer assembly. In the unloading assembly, the die holders transferred from the die transfer assembly are placed on two belts. A feeding motor drives multiple rotating wheels to rotate, which in turn drives the two belts to rotate synchronously, thereby transferring the die holders to the next station. The die holder is the substrate.
[0004] The aforementioned technologies have the following drawbacks:
[0005] During the process of transferring the substrate to the support transfer assembly and during the process of transferring the substrate out of the support transfer assembly, the substrate is transferred over a relatively long distance. Moreover, the substrate is mainly transported by belt through friction. Given that the belt is long and is a flexible structure, the substrate inevitably shakes or wobbles during long-distance transfer, resulting in low stability, which needs to be improved.

[0145] In summary, the working process of the substrate transport module provided in this application is roughly as follows:
[0146] After the substrate supply mechanism 102 transfers the substrate from the substrate output port, the loading clamping and conveying mechanism 103 clamps and fixes the substrate and moves it to the transfer mechanism 104. The transfer mechanism 104 then transfers the substrate to the die bonding station. After the die bonding operation, the substrate becomes a substrate. The transfer mechanism 104 then conveys the substrate to the unloading clamping and conveying mechanism 105. The unloading clamping and conveying mechanism 105 clamps and fixes the substrate and moves it to the recycling and connecting mechanism 106. The recycling and connecting mechanism 106 then transfers the substrate into the substrate storage mechanism 107.
[0147] The beneficial technical effects of the substrate transport module provided in this application are roughly as follows:
[0148] The addition of a loading clamping and conveying mechanism 103 and a unloading clamping and conveying mechanism 105 mainly transfers the substrate by clamping it. Compared with belt conveyor transfer, the structure is simpler, the substrate is less prone to shaking and wobbling during the transfer process, and the transport stability is improved. At the same time, the entire substrate transport module has a linear structure, which greatly shortens the transport path length of the substrate, shortens the transfer time, and has a faster operating speed, thus improving the die bonding efficiency and accuracy.

The die bonder module includes a die supply mechanism, a die ring platform, a ejector mechanism, a camera unit, and a die bonder mechanism. The die bonder designed above significantly shortens the substrate transport path length, reduces the substrate transfer time, operates at a faster speed, and improves die bonder efficiency and accuracy.
[0150] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
