Description

Technical Field

[0001] The utility model relates to the technical field of BGA chip ball planting, in particular to a universal ball planting platform device with replaceable fixtures. Background Art

[0002] With the rapid development of the electronics industry, the integration capability of electronic products is constantly improving, and the requirements for the packaging and ball planting process of BGA chips are also increasing. The diameter of the solder balls is required to be smaller and smaller, so there is a certain probability of defective products such as bridges, large and small balls, missing balls, multiple balls, cold solder joints, and misalignment in the process of mass production. These defective BGA chips need to be repaired for the defective points to remove the defective solder balls and then perform ball planting corrections. There are two main traditional conventional repair methods in the industry:

[0003] 1) Use electric iron and solder sucking wire to remove all solder balls from the entire BGA chip, and then use the ball planting table to manually plant the balls;

[0004] 2) Manually under a microscope, use tweezers to scrape off the defective solder ball, then use tweezers to place a new solder ball and then re-plant the ball.

[0005] Both methods have obvious defects. When the first method uses a traditional electric soldering iron to clean the solder balls, the surface of the solder sucking wire is very rough, which will greatly reduce the adhesion of the metal pad on the circuit board. If you are not careful, the pad will be taken away, resulting in direct product scrapping. Moreover, this method is to remove all the solder balls on the entire BGA and then re-plant the entire piece. This method will greatly waste materials such as solder balls, making it difficult to reduce the maintenance-oriented, and also increase the risk of BGA scrapping due to careless tin removal and the risk of scrapping due to low success rate of secondary ball planting. The second method requires extremely high manual proficiency, and the overall repair yield is relatively low, generally only about 60%, and employees need to work under a microscope for a long time, causing irreversible damage to the employees' eyes. In addition, as BGA chips become smaller and smaller, the diameter of the solder balls is also getting smaller, and the difficulty of maintenance is increasing exponentially. Manual labor can no longer meet the rework of BGA chips with solder ball diameters below 0.3mm.

[0006] At present, there is an online ball replenishing equipment (such as patent number 202210045273.2) that can solve the above-mentioned problems existing in manual ball planting and ball replenishing. However, in this equipment, the platform used by the ball planting fixture is fixed, that is, it can only adapt to the ball planting of one type of product. If the ball planting process is to be performed on other types of products, it is necessary to stop the machine, then disassemble the fixture platform, and then reinstall the new platform, which is time-consuming and labor-intensive, and greatly reduces work efficiency. Therefore, it needs to be improved. Utility Model Content
