What is a BGA rework station to figure out this problem?

April 04, 2023

The BGA Rework Station (BGA Rework Station) is a soldering facility that repairs BGA packages.BGA maintenance workstation is generally divided into automatic and manual. By positioning BGA components of different sizes, welding and disassembling intelligent operation equipment, the productivity of maintenance rate can be effectively improved and the cost can be greatly reduced.The traditional rework method is the manual welding of BGA, which refers to the process of removing and welding BGA, QFN, QFP and other electronic components with hot air gun, electric iron and other tools.With the rise of domestic BGA equipment manufacturers, domestic enterprises slowly accepted BGA repair equipment and gradually introduced it into the production workshop, and the repair process was improved.In this process, the BGA rework table has greatly improved the success rate of rework welding, and even replaced the hot air gun and electric iron, becoming the mainstream rework equipment.The BGA rework equipment can complete operations that cannot be completed by ordinary soldering tools, such as optical alignment. For example, the BGA rework table can avoid the deformation of the reworked motherboard to a greater extent, and also ensure that the BGA is not damaged.With the development of SMT equipment, ball mounting machine, tin remover and other automatic auxiliary equipment have not been widely used today. Hot air gun and electric iron combined with other tools and auxiliary materials have also played a great role in the field of repair.Compared with manual welding, the advantages of BGA rework table are obvious.

What is a BGA Rework Station?For people outside the BGA rework table industry, this is indeed a very vague concept, of course, there are many people do not know the answer to this question.But for people in the industry, this problem is not a problem, because after the rapid development of the BGA repair industry in recent years, almost all the practitioners in the BGA repair industry know and use the BGA rework table.So what exactly is a BGA rework station?To understand this problem, we must first understand what BGA is.BGA is a chip packaging technology, which is to improve the performance of digital products and reduce the size of products through the ball grid array structure.All digital products through this packaging technology have a common characteristic, that is, small size, strong performance, low cost and powerful function.Knowing what a BGA is, it is easy to know what a BGA rework station is. A BGA rework station is a machine used to repair BGA chips.When a chip is detected to have a problem and must be repaired, the BGA rework station must be used.Using the BGA rework station to rework the BGA has several advantages over not using the BGA rework station: First, the rework success rate is high.At present, the new generation of optical alignment BGA rework table launched by our company can achieve the success rate when repairing BGA.Secondly, the operation is simple.Using the BGA rework station to repair BGA, any novice who has not been exposed to BGA can become a BGA rework master in a few minutes of learning process.And thirdly, that BGA chip and the PCB board are not easy to be damage by using the BGA rework table.As we all know, when repairing BGA, high temperature heating is needed. At this time, the requirement for temperature control accuracy is very high. A slight error may lead to the scrap of BGA chips and PCB boards.However, the temperature control accuracy of the BGA rework station can be within 2 degrees, which can ensure the integrity of the chip in the process of reworking the BGA chip.
