Problems solved by technology

[0005] However, the loading process of the lead frame array in the prior art is usually done manually. Therefore, the efficiency of the loading process is low, while the placement efficiency of SMT is high, and the time for manually placing the lead frame to the DBC substrate jig is far away. It is higher than the chip mounting time, therefore, the lead frame loading process restricts the improvement of packaging efficiency
[0006] In addition, the automation of the manual lead frame array loading process is low. During the material loading process, lead frame array placement errors (for example, reverse lead frame, wrong lead frame) are prone to occur, which affects the packaging process and packaging. product quality

Abstract

The invention provides a feeding system of a lead frame array and belongs to the technical field of encapsulation. The feeding system of the lead frame array comprises a material pushing device, a sucking module, a detecting module and a transferring module. The material pushing device is used for pushing the lead fame array out of a lead frame array material box. The sucking module is provided with a plurality of suction nozzles used for sucking the lead frame array, and the detecting module is provided with a detection sensor used for detecting the placing direction and the type of the lead frame array. The transferring module is used for transmitting the lead frame array sucked by the sucking module to a reserved part. The feeding system of the lead frame array is high in degree of automation. The lead frame array is little in deformation and high in encapsulation efficiency in the process of feeding. In addition, the accuracy of feeding load is high.

Description

technical field [0001] The invention belongs to the technical field of packaging, and relates to a mounting fixture for a direct bonding copper (Direct Bonding Copper, DBC) substrate. Background technique [0002] The lead frame is one of the main carriers for packaging chips. Before packaging and bonding, the process of material loading and other processes is carried out in the form of a lead frame array, which is conducive to improving the packaging efficiency. [0003] In the packaging production line, it is usually necessary to position the lead frame array on the predetermined component first, which is called the loading process of the lead frame array. For example, the lead frame array needs to be positioned and loaded into the predetermined DBC (Direct Bonding Copper, direct Bonding copper) on the substrate fixture; then complete SMT (Surface Mounted Technology, surface mount technology) mounting on the DBC substrate. [0004] SMT (Surface Mounted Technology) is ...
