BGA rework stations which are also referred to as SMD and SMT rework stations are very important in the modification and repair of the printed circuit board. From their names, rework stations can be seen as spaces whereby circuit boards and surface-mounted devices can be altered by technicians with BGA packaging.
BGA rework stations are great for several repairing and refinishing applications, which includes getting rid of defective components, replacing components that are missing, reversing incorrectly installed components, and more.
Many low-volume or short-run or production operations utilize BGA rework stations. With respect to the system and task, these stations may provide partial automation capabilities, using or without using a connected PC. These bga machines are totally self contained having their own individual internal vacuum and air unless specified otherwise.
What Is a BGA Rework Station?
A BGA rework station can be defined as a workspace which technicians use in altering PCBs with surface-mounted devices and BGA – ball grid array packaging. These stations can cause changes in circuit boards as well with chip packages, grid array packaging, land arrays, flat packages, as well as other SMDs. These rework stations can also be referred to as SMD – surface-mounted device rework stations, as well as SMT – surface-mounted technology rework stations.
These stations come with great features, which can tell the circuit board’s size that work can be done on and abilities determining the volume and types of jobs to be done. There are BGA stations having assist cameras with split-vision; however, not all of them do. BGA stations lacking this split-vision function are usually great for entry jobs, while those having this function ensure that more difficult jobs can be handled. Also some stations come with automated functions.
BGA rework stations let technicians perform different things, which include repair, rework, and refinishing. These stations also empower and help technicians in reinstalling parts that are incorrectly attached, removing defective parts, replacing parts that are missing, and removing damaged parts. You can place BGA rework stations on surfaces that are flat. Technicians can also make use of BGA stations that are cabinet-mounted and have wheels.
Benefits of BGA Rework Stations
The BGA station stands for a great investment. However, they have many great benefits.
Accuracy: The BGA rework station is regarded as a complex process, which requires great detail and skill. It is very easy to destroy or damage the whole PCB anytime you try reworking a BGA. These rework stations provide the necessary tools to successfully achieve the right precision to get the rework completed safely and accurately, without causing damage to the whole device.
Efficiency: These very specialized tools like solder balls, pickup tubes, and nozzles, which are usually found in BGA rework stations, make sure that trained technicians tackle their rework job efficiently.
Volume: With the appropriate BGA rework station, companies such as equipment manufacturers can be aided in handling a large quantity of jobs on several PCBs with different sizes.
Cost: The initial BGA rework station price is a great investment. However, it is worth it. With rework, your PCB’s lifetime can be extended significantly. Also, it costs less to handle a PCB rework than buying or assembling one that is new.
Application of BGA Rework Stations
A BGA rework station can be applied in different ways in the PCB alteration and repair world. The following are just a few areas of where BGA rework machines are most commonly used.
Upgrades: These are regarded as one very common reason for rework. In some cases, technicians may see the need to add upgraded pieces to PCBs.
Faulty or damaged parts: Some parts in PCBs can become faulty and may need rework. While BGA removal is on, pads may get damaged. Also, one or more of the parts can become heat-damaged. There can be high solder voiding as well.
Faulty assembly: Some mistakes may happen whenever a rework is on. There may be a wrong BGA orientation of the PCB. The thermal profile could be poorly developed too. If this happens, then there may be a need for the PCB to go through more rework to help in addressing this faulty assembly.
Infrared (IR) vs. Hot Air BGA Rework Machines
The BGA rework stations used by PCB contract producers as well as manufacturers of original equipment are of two types. These include the infrared and hot air. What differentiates between both BGA rework machines? Also, which is better between the two?
Hot Air Rework Stations
This makes use of hot air in heating up the components of the PCB all through the project. Different nozzles circulate and guide hot air in order to make sure that heat is distributed evenly. These nozzles can be moved by technicians to direct the air, which allows for quick accomplishments when working on delicate and small components.
You’ll hear some noise whenever you use air pumps for your hot air rework station. Although, there are many models that operate very quietly. Due to the fact that hot air technology is older, there are more technicians trained to use hot air stations compared to those using IR rework stations.
IR Rework Stations
Rather than use hot air, the IR rework stations heat components of PCB making use of infrared rays coupled with fixed ceramic heaters. The IR BGA rework station operates silently. Also, fewer pieces are involved, which could ensure that maintenance comes easier.
However, with respect to the machine’s quality, there may be a need for frequent maintenance. Also, you may need additional tools in order to help you achieve and accomplish your desired jobs. This technology is newer, as a good number of technicians don’t have the necessary training to make use of IR BGA stations.
These two BGA stations have their benefits and pitfalls. However, an important factor anyone must look into is how skillful the technician handling the machine’s operations will be.
