What should we pay special attention to when determining the placement height of the PCB BGA rework station?

When determining the mounting height of the PCB BGA rework station, you need to pay attention to the following points:

  1. Determine the height of the chip: First, you need to determine the height of the chip to be repaired in order to adjust the height of the placement head. The height of the chip can be obtained by measuring the size of the chip or consulting the chip’s technical manual.
  2. Adjust the height of the placement head: Adjust the height of the placement head according to the height of the chip. Generally speaking, the height of the placement head should be consistent with or slightly higher than the height of the chip. If the height of the placement head is too low, it may not be able to pick up the chip or the suction force is insufficient; if the height of the placement head is too high, it may cause excessive pressure on the chip, thereby damaging the chip or circuit board.
  3. Confirm the suction power of the placement head: After determining the placement height, you need to confirm whether the suction power of the placement head is sufficient. If the suction power is insufficient, the chip may not be placed correctly or may fall off. Generally speaking, the suction power of the placement head can be adjusted by adjusting the air pressure or replacing the adsorption sheet.
  4. Pay attention to the placement position of the chip: After determining the mounting height and suction force, you need to pay attention to the placement position of the chip. Generally speaking, the chip should be placed in the center of the placement head to ensure placement stability and accuracy. If the chip is not placed correctly, it may cause the chip to be offset or tilted after placement, which will affect the soldering effect and the performance of the circuit board.
    When determining the placement height of the PCB BGA rework station, you need to pay attention to the height of the chip, the height of the placement head, the suction force, and the placement position of the chip to ensure the accuracy and reliability of the rework.

What is the working principle of PCB BGA welding machine?

The working principle of the BGA welding machine is to use infrared rays or lasers to melt the solder balls and weld them to the chip. During the BGA welding process, the chip is first placed in a heated environment for preheating. This stage is to bring the solvent to the desired viscosity and screen printing performance, and to prevent boiling and splashing. Next, the flux becomes active, cleaning metal oxides and certain contaminants from the metal and solder particles that are about to join. When the temperature continues to rise, the solder particles first melt individually and begin the “light grass” process of liquefaction and surface absorption of tin. This covers all possible surfaces and begins to form solder joints. Finally, the welding is completed.

What are the uses of PCB bga rework stations?

The PCB BGA rework station is mainly used to disassemble and solder BGA packaged IC chips. Its uses include:

  1. Electronic manufacturing and assembly: During the electronic manufacturing and assembly process, problems such as poor welding of BGA packages, component damage, or assembly errors may occur. The BGA rework station can be used to quickly and accurately rework these problems to ensure product quality and performance.
  2. Electronic product repair and maintenance: During the use of electronic products (such as mobile phones, laptops, tablets, etc.), due to various reasons, BGA packaged integrated circuits may malfunction or be damaged. The BGA rework station can be used to disassemble and replace these faulty components and restore the normal operation of the equipment.
    In addition, the BGA rework station can also be used for research and education. For example, in the teaching of electronic engineering and related majors, students can learn and master BGA packaging technology and welding technology through the BGA rework station.

How to operate the PCB bga rework station?

The operating steps of the PCB BGA rework station are as follows:

  1. Preparation: Place the BGA chip on the rework table and fix the PCB motherboard. The temperature for rework is determined based on the leaded and lead-free soldering used, because the melting points of solder balls are different. At the same time, set the desoldering and welding temperatures so that they can be called directly during future repairs.
  2. Heating and desoldering: At the end of the second constant temperature period, the temperature of the BGA should be maintained between 150-190°C (lead-free) or 150-183°C (lead-containing). If it is too high, you can lower the temperature of the heating section or shorten the time; if it is too low, you can increase the temperature or time of the preheating section and the heating section. Then switch to the removal mode on the touch screen interface, click the repair button, and the heating head will automatically come down to heat the BGA chip. After the temperature curve is completed, the suction nozzle will automatically pick up the BGA chip, and then the placement head will suck the BGA and rise to the initial position.
  3. Placement: Switch to the placement mode, click the start button, the placement head will move downward, and the nozzle will automatically pick up the BGA chip to the initial position.
