What is BGA Reballing?
BGA (Ball Grid Array) reballing is a process of replacing the solder balls on a BGA chip or package. It involves removing the old, damaged solder balls and replacing them with new ones to restore the electrical connection between the chip and the printed circuit board (PCB). This process is often necessary when the solder balls have become damaged due to physical stress, thermal cycling, or manufacturing defects.
Why is BGA Reballing Important?
BGA reballing is crucial for several reasons:
- It restores functionality to damaged electronic devices, such as smartphones, tablets, laptops, and gaming consoles.
- It extends the lifespan of electronic devices, reducing electronic waste and saving money for consumers.
- It enables the repair of complex electronic components that would otherwise need to be replaced entirely.
The BGA Reballing Process
Step 1: Removal of the BGA Chip
The first step in the reballing process is to remove the BGA chip from the PCB. This is typically done using a hot air soldering station, which heats the solder balls until they melt, allowing the chip to be lifted off the board.
Step 2: Cleaning the BGA Chip and PCB
Once the chip is removed, both the chip and the PCB must be cleaned thoroughly. Any remaining solder or flux residue is removed using a soldering iron and solder wick or a specialized cleaning solution.
Step 3: Applying New Solder Balls
Next, new solder balls are applied to the BGA chip. This is done using a reballing stencil, which ensures that the balls are placed in the correct positions and at the proper height. The solder balls are then reflowed using a hot air soldering station or an infrared reflow oven.
Step 4: Reattaching the BGA Chip
Finally, the reballed BGA chip is reattached to the PCB. This is done by aligning the chip with the PCB using a pick-and-place machine or by hand, then reflowing the solder balls to create a strong electrical and mechanical connection.
Choosing a BGA Reballing Company
When selecting a BGA reballing company, there are several factors to consider:
Experience and Expertise
Look for a company with extensive experience in BGA reballing and a proven track record of successful repairs. The company should have technicians who are skilled in working with a wide range of electronic devices and components.
Equipment and Facilities
A reputable BGA reballing company should have state-of-the-art equipment, including hot air soldering stations, reflow ovens, and inspection microscopes. They should also have a clean, well-maintained facility to ensure the best possible results.
Turnaround Time and Pricing
Consider the company’s turnaround time and pricing. While it’s essential to get your device repaired quickly, be wary of companies that offer extremely low prices or unrealistically fast turnaround times, as this may indicate a compromise in quality.
Customer Service and Support
Choose a company that offers excellent customer service and support. They should be responsive to your inquiries, provide clear communication throughout the repair process, and offer a warranty on their work.

Frequently Asked Questions
How long does BGA reballing take?
The time required for BGA reballing varies depending on the complexity of the device and the extent of the damage. Generally, the process can take anywhere from a few hours to a few days.
Is BGA reballing expensive?
The cost of BGA reballing depends on several factors, including the type of device, the complexity of the repair, and the BGA reballing company you choose. On average, prices can range from $100 to $1,000 or more.
Can I do BGA reballing myself?
While it is possible to perform BGA reballing yourself, it is not recommended unless you have extensive experience and the proper equipment. BGA reballing requires precision, skill, and specialized tools, and attempting it without the necessary expertise can result in further damage to your device.
How can I tell if my device needs BGA reballing?
Some common signs that your device may need BGA reballing include:
– Intermittent functionality
– No power or display
– Overheating
– Physical damage to the device
If you experience any of these issues, it’s best to consult a professional BGA reballing company for an assessment.
Is BGA reballing a permanent fix?
When performed correctly by a skilled technician, BGA reballing can be a permanent fix for many electronic devices. However, the longevity of the repair depends on various factors, such as the quality of the solder balls used, the cleanliness of the repair environment, and the device’s exposure to physical stress and thermal cycling.
Conclusion
BGA reballing is a crucial process for restoring functionality to damaged electronic devices and extending their lifespan. When choosing a BGA reballing company, it’s essential to consider factors such as experience, equipment, turnaround time, pricing, and customer support. By selecting a reputable company, you can ensure that your device receives the best possible care and that the repair is performed to the highest standards.
