How does a BGA rework station work?

A BGA rework station allows technicians to do several different things, including refinishing, rework and repair. These rework stations empower technicians to remove defective parts, reinstall incorrectly placed parts, replace any missing parts and remove parts that are no longer working.

How many times can a BGA be reworked?

O’Brien points out, a board with one reflow cycle has margin for only one BGA replacement. So we limit our assembly suppliers to 6 thermal cycles at any one site, but only one BGA replacement.

How is BGA reflow?

The BGA soldering technique In the PCB assembly process, the BGA is soldered on to the circuit board by the solder reflow process, using a reflow oven. During this process, the solder balls melt in the reflow oven.

How do you’re ball a BGA?

In order to reball a BGA, you will need a soldering iron. A soldering iron is a hand-based apparatus that is designed for soldering projects. It will send heat to the solder metal so that it can be melted to optimize flow into the broken joints between the electronic component and the PCB itself.

Is solder paste needed for BGA?

In most cases BGA rework can be achieved, and is often more reliable, without addition of solder paste (i.e., using only the solder balls). This assumes a good site prep and proper flux process. In cases where there may be planarity issues, solder paste can be beneficial.

How do you assemble a BGA?

BGA Soldering by Hand

1. Apply Flux Paste (Not Liquid Flux) on to the pad.
2. Place solder balls very carefully on the pad.
3. Apply paste flux to the bottom (soldering side) of the BGA package.
4. Carefully place the BGA Package on the solder balls.
5. Preheat and then apply Hot Air with Hot Air Blower from both top and bottom.

Why is reballing necessary?

Jaywn, reballing is usually performed to replace a BGA IC, not a device. It has become somewhat more accepted to reflow devices like PS3 XBox etc. Most of the time a reflow is based on generally known failures. It is the thermal cycling that causes the following in Lead-Free Solder over time.

Do I need solder paste for BGA?

Can a BGA be Reballed?

Our high-reliability BGA Reballing service can quickly rework BGA components that require reballing. Reballing is most often required when the alloy of the BGA component solder balls needs to be changed from lead-free to leaded.

How many times can you rework a PCB?

The total number of heat and cooling cycles should be part of the decision to limit the number of rework cycles. In general, the typical number of rework attempts (multiply by two to get to the number of heat cycles) for Class-2 and Class-3 PCBs is three.

How do you become a BGA?

What are the steps of BGA repair?

1. First, remove the components, such as the PCB.
2. Next, remove the residual solder.
3. Once you have removed all the excess solder, the BGA can be reballed.
4. After the excess solder has been removed and the BGA has been reballed, the components and PCB can be re-soldered and reattached.
