10. The relevant knowledge for automatic reballing infrared BGA repair machine
Using a BGA rework station can be roughly divided into three steps: desoldering, placement, and soldering. Below, we take the BGA rework station DH-A2 as an example:
Desoldering:
1,Preparation for Repair: Determine the air nozzle to be used for the BGA chip being repaired. The rework temperature is set according to whether leaded or lead-free solder is used by the customer, as the melting point of leaded solder balls is generally 183°C, while the melting point of lead-free solder balls is around 217°C. Fix the PCB motherboard on the BGA rework platform and align the red laser spot at the center of the BGA chip. Lower the placement head to determine the correct placement height.
2,Set the Desoldering Temperature: Store the temperature setting so it can be recalled for future repairs. In general, the temperature for desoldering and soldering can be set to the same value.
3,Start Desoldering: Switch to disassembly mode on the touch screen interface and click the repair button. The heating head will automatically lower to heat the BGA chip.
4,Completion: Five seconds before the temperature cycle ends, the machine will sound an alarm. Once the temperature curve is completed, the nozzle will automatically pick up the BGA chip, and the placement head will lift the BGA to the initial position. The operator can then connect the BGA chip to the material box. Desoldering is now complete.
Placement and Soldering:
1,Placement Preparation: After the tin removal from the pad is complete, use a new BGA chip or a reballed BGA chip. Fix the PCB motherboard and approximately position the BGA on the pad.
2,Start Placement: Switch to placement mode, click the start button, and the placement head will move down. The nozzle will automatically pick up the BGA chip and move it to the initial position.
3,Optical Alignment: Open the optical alignment lens, adjust the micrometer, and align the PCB on the X and Y axes. Adjust the BGA angle with the R angle. The solder balls (displayed in blue) on the BGA and the solder joints (displayed in yellow) on the pad can be seen in different colors on the display. After adjusting so that the solder balls and joints completely overlap, click the "Alignment Complete" button on the touch screen.
4,Completion: The placement head will automatically lower, place the BGA on the pad, and turn off the vacuum. The head will then rise by 2-3mm and begin heating. Once the temperature curve is completed, the heating head will rise to the initial position. Soldering is complete.
Soldering:
This function is used for BGAs that are poorly soldered due to low temperature and require reheating.
1,Preparation: Fix the PCB board on the rework platform and position the laser red dot at the center of the BGA chip.
2,Start Soldering: Set the temperature, switch to welding mode, and click start. The heating head will automatically lower. After contacting the BGA chip, it will rise by 2-3mm and then start heating.
3,Completion: After the temperature curve is completed, the heating head will automatically rise to the initial position. Soldering is now complete.
