What is BGA Reballing?

BGA (Ball Grid Array) reballing is a process of replacing the solder balls on a BGA chip or package. This process is often necessary when the original solder balls have been damaged or have deteriorated, causing issues with the device’s functionality. Reballing involves removing the old solder balls, cleaning the pads, and then applying new solder balls to the package.

The Importance of BGA Reballing

BGA reballing is crucial for many industries, including:

• Electronics manufacturing
• Aerospace
• Automotive
• Medical devices
• Consumer electronics

Without proper BGA reballing, devices may experience:

• Intermittent failures
• Complete device failure
• Reduced lifespan
• Decreased reliability

The BGA Reballing Process

The BGA reballing process typically involves the following steps:

1. Inspection: The device is inspected to determine the extent of the damage and the specific BGA package that needs to be reballed.

2. Removal: The old solder balls are removed using specialized equipment, such as a BGA Rework station or a hot air soldering iron.

3. Cleaning: The pads on the PCB and the BGA package are cleaned to remove any residue or oxidation.

4. Alignment: The BGA package is aligned with the PCB using specialized alignment tools to ensure proper placement.

5. Reballing: New solder balls are applied to the BGA package using a reballing stencil and solder paste.

6. Reflow: The device is heated to melt the new solder balls and create a strong connection between the BGA package and the PCB.

7. Inspection: The device is inspected again to ensure proper connectivity and functionality.

BGA Reballing Equipment

To perform BGA reballing, companies use specialized equipment, such as:

• BGA rework stations
• Hot air soldering irons
• Reballing stencils
• Solder paste
• Alignment tools
• Microscopes for inspection

Choosing a BGA Reballing Company

When selecting a BGA reballing company, consider the following factors:

Experience and Expertise
