At present, there are many products using BGA packaging in the market, such as notebooks, mobile phones, webcams, computer motherboards and other products, which basically use BGA packaging technology. At the same time, the technical difficulty of BGA maintenance is not low, so it is very important to choose a good BGA repair table. Today, Dataifeng Technology will give you a general explanation of some problems that need to be paid attention to about the BGA rework table. I. Basic issues1. PCB size of the repaired productGenerally, most of the customers who buy BGA rework tables are used to repair notebook computers or desktop computers, so there is no need for BGA rework tables with large worktops at this time. The BGA repair table of Dataifeng Technology is enough to meet the BGA repair of computers on the market. The specific situation should be decided according to the actual maintenance situation of the individual, so the size of the PCB splint needs to be paid attention to.2. The problem of chip sizeThere is no need to worry about this problem, because under normal circumstances, the supplier will provide the corresponding tuyere, and the relevant size can be customized.II. Functional issues1. Three temperature zonesThe three temperature zones mainly refer to the upper, lower and bottom heating areas of the machine. At present, Dataifeng Technology adopts three temperature zones controlled by independent programming: the upper temperature zone and the lower temperature zone are heated by convection hot air, and the lower temperature zone adopts a large area heating wire layout.2. Temperature curve temperature controlThe rework of BGA is not a matter of melting the tin at once and removing the chip. A high-quality repair needs to use the temperature curve to repair, through the adjustment and control of temperature, to reduce the damage to the chip itself in the heating process. Moreover, the temperature curve control through software settings can ensure the accuracy of the temperature, and at the same time, the change of the temperature itself can be observed.The important points are probably the above. Of course, after-sales service and brand are also very important, which is a guarantee for the product itself. Shenzhen Dataifeng Technology Co., Ltd. is a SMT solution provider integrating R & D, production and sales, and a well-known brand in Shenzhen.
