Can a BGA be Reballed?
Reballing is most often required when the alloy of the BGA component solder balls needs to be changed from lead-free to leaded. Every BGA Reballing project is completed to meet IPC and JEDEC specifications.
How do you rework a BGA?
What are the steps of BGA repair?
- First, remove the components, such as the PCB.
- Next, remove the residual solder.
- Once you have removed all the excess solder, the BGA can be reballed.
- After the excess solder has been removed and the BGA has been reballed, the components and PCB can be re-soldered and reattached.
What is a BGA failure?
BGA failure analysis is made difficult by the high density of I/O pins in the Ball Grid Array (BGA) devices. BGA packaging involves the packing of large numbers, sometimes upwards of 400 to 500 I/O pins, into a relatively small area, which is their primary advantage to manufacturers.

What is re balling?
Reballing involves dismantling, heating the chip until it can be removed from the board, typically with a hot-air gun and vacuum pickup tool, removing the device, removing solder remaining on the device and board, putting new solder balls in place, replacing the original device if there was a poor connection, or using …

Why is reballing necessary?
Why a BGA Chip May Need Reballing The first reason is overuse. That is, the overuse of a graphics chip, which may involve running it for a prolonged time or extended use into several days, may require BGA reballing. More often than not, the solder joints between the PCB and the chip will become loose over time.
What temperature should I reflow my BGA?
If you must use lead-tin solder paste with lead-free BGA packages, ensure that the reflow temperature is high enough to provide a reliable interconnection. A minimum peak temperature of 220°C is recommended, but a range of 225–245°C (for qualified components) is preferred.
How long does reballing last?
120 Minutes – Total Time for a REBALL. This is assuming you have no distractions and you do it perfectly! Add extra 50 minutes if you missed a ball and have to do it all over again.
Why Reballing is done?
How much does reballing cost?
The process involves detatching the gpu or cpu using a very expensive tool then replacing the gpu or cpu dots with a reballing device. This process costs $100, and I need to go to a third party computer repair shop to get my laptop reballed.
What temp does GPU solder melt?
Most lead-free solder used in electronics starts to melt and become liquid at 217 degrees. EXACTLY. You can heat it to about 222-224 degrees and that’s it. You keep the heat at that temp applied for about 20 seconds, which is called the dwell time.
