BGA rework station is a kind of equipment specially used for repairing BGA (Ball Grid Array) chips, which are a kind of surface-mounted electronic devices, widely used in various electronic products, such as computers, cell phones, game consoles, etc. BGA chips are also widely used for the repair and maintenance of electronic products.
I. Characteristics of BGA chips
BGA chips are characterized by spherical tin-lead or tin-silver-copper solder balls placed on its bottom, which form the electrical path to the PCB. Due to their unique design, BGA packages can offer higher pin counts and are smaller than conventional package forms, making them widely used in high-performance electronic devices.
However, due to the complexity of BGAs and the tiny solder area, it can be very difficult to repair a chip if it has a problem. This is where the BGA rework station comes into play.
II. Role of the BGA Rework Station
The BGA rework station allows the technician to precisely control the repair process, including the speed of heating and cooling, as well as the precise alignment of the soldered area. This is achieved through the use of advanced hot air rework technology and high precision optical alignment systems.
The BGA rework station is also equipped with many other advanced features, such as a built-in high definition microscope for checking the quality of the soldering, and automated software for controlling the entire repair process.
III. Basic steps for BGA chip repair using a BGA rework station
1. Identify and locate the problem: First, the technician needs to determine which BGA chip needs to be repaired and pinpoint the exact location of the problematic solder.
2. Heat and Remove: Using the heating system of the BGA rework station, the technician can precisely control the heating process in order to remove the problematic BGA chip without damaging the surrounding components.
3. Cleaning and Preparation: Once the defective chips have been removed, the technician needs to clean and prepare the PCB in order to install the new BGA chips.
4. Installation of new BGA chip: The new BGA chip is placed in the proper location and soldered into place using the rework station's heating system.
5. Inspection and Testing: Finally, the technician needs to check the quality of the new soldering and perform tests to ensure that the new chip is working properly.
Features of NeoDen BGA rework station
1. The linear slide base allows the X, Y and Z axes for precise fine-tuning or quick positioning action.
2. Touch screen controls the heating system and optical alignment device for convenient and flexible operation to ensure alignment control accuracy.
3. Advanced programmable temperature control system is selected to achieve multiple precise temperature control.
4. The three-temperature area is heated independently, the temperature is accurately controlled in ± 3℃, and the infrared heating plate can make the PCB board heat evenly.
5. The PCB board positioning uses the V-shaped card slot, flexible and convenient mobile universal fixture, to protect the PCB board.
