Description

Technical Field

[0001] The invention relates to the technical field of semiconductor welding, in particular to a welding packaging mechanism. Background Art

[0002] Welding packaging technology is the process of assembling integrated circuits into final chip products. Simply put, it is to place the integrated circuit components produced by the foundry on a supporting circuit board, and then use welding to solder the pins of the integrated circuit components to the circuit board, and then fix the package into a whole production and processing technology.

[0003] The existing Chinese patent application with publication number CN116441800A discloses a lead welding device for TOLL packaging processing, including an equipment housing and a lead welding module, wherein the lead welding module is arranged in the equipment housing, and also includes a four-station electric turntable and an optical detection module, wherein the four-station electric turntable is horizontally arranged in the equipment housing, and each station of the four-station electric turntable is provided with a positioning module, each positioning module can quickly and accurately position the grain lead frame in a horizontal state without blocking the top of the grain lead frame, and the optical detection module is arranged in the equipment housing for performing appearance defect detection on the finished grain welding product; the invention can quickly and accurately position the lead frame through the positioning module, and can also avoid blocking the top of the lead frame and the grain, thereby improving work efficiency and ensuring the accuracy of the lead frame during lead welding of the grain and the detection accuracy of the optical detection module.

[0004] However, the welding packaging device has the following defects when used:

[0005] 1. When the existing welding and packaging devices are used to weld and package various electrical components on components such as circuit boards inside semiconductors, in order to improve the efficiency of circuit board welding and packaging, they generally use a conveying method to move the circuit board to be welded and packaged to the position of the welding gun, and remove the circuit board that has been welded and packaged from the bottom of the welding gun for subsequent inspection and other operations. However, in actual operation of the above scheme, for the welded circuit board, the temperature generated by welding will cause the temperature of the welding position of the electrical components to be higher. When the subsequent inspection and other operations are performed on the welded circuit board, the high temperature will affect the accuracy of the inspection of the circuit board;

[0006] 2. When welding and packaging electrical components on a circuit board, the existing welding and packaging device needs to move the electrical components to be welded to the corresponding welding position of the circuit board. At this time, belt transportation and cylinder grabbing and adsorption are generally used to fix and transport the electrical components and move them to the corresponding packaging welding position of the circuit board. The transportation of electrical components requires an additional drive component for driving, which causes greater vibration during the entire circuit board welding and packaging process, which will affect the stability of the welding packaging on the one hand, and increase the cost of the entire welding packaging on the other hand.

[0053] 4.
