BGA PCB By Package Type
What is BGA (Ball Grid Array) in a PCB?
A ball grid array (BGA) is a type of surface mount packaging (SMD) that’s used to mount ICs (integrated circuits) to a printed circuit board (PCB). The BGA package is composed of a substrate, solder balls and an integrated circuit in the center.
In a BGA assembly process, the chip is mounted on the BGA substrate and then each lead from the chip is soldered to the solder balls in a grid pattern. Then the whole structure is encapsulated with resin.
BGA packages can be found in many consumer electronics devices such as cell phones, smart watches and laptops.
Manufacturing with BGA PCB: Process and Inspection
BGA PCB manufacturing is a process that is used to create circuit boards with ball grid arrays soldered to them. These circuits are generally used in high-end computers and other products that require a large number of connections between the different components of the system.
The process begins by creating a design for the circuit board, which will be printed onto a photoresist layer on top of a silicon wafer. This photoresist layer is then exposed to UV light, which causes it to harden into an opaque form, thereby creating patterns that align with where electronic components should be placed during assembly.
The inspection of BGA PCBs is an important step in the manufacturing process. It is important to ensure that all components are properly placed, soldered and aligned. This will ensure that your product will work as desired after the manufacturing process.
Why do BGA PCBs Need Special Handling?
BGA PCBs need special handling because of the way they are designed. BGA stands for Ball Grid Array, and it refers to the way that the connections on a BGA PCB are laid out.
The connections on a BGA PCB are laid out in a grid pattern with small balls of solder between each connection. This means that if you were to just press down on the board, you’d likely cause all of the connections to touch together and short-circuit your board.
BGA PCBs need special handling because the solder joints are delicate, and the package can be easily damaged. The PCBs are also more prone to failure if they are bent or flexed.

BGA PCB Fabrication
BGA stands for Ball Grid Array, while FBGA stands for Fine Pitch Ball Grid Array. The difference lies in the pitch of the pins and pads on the board.
In a BGA board, the distance (or pitch) between each pin is small, which means that it is easier to solder individual components onto this type of board. However, because of its small size, it is more difficult to work with than an FBGA board.
An FBGA board is larger than a BGA board because the distance between pins or pads is greater apart than on a BGA board. This makes it easier to work with than a BGA board because you have more room to move around on the board when soldering components into place.
The Assembly Board of BGA PCB is a testing board that allows you to test your product in a realistic environment. It uses real-life BGA components and has connectors for the cables that will go on it. The board also has a variety of test points that allow you to run tests on various parts of your product.
Testing your product before you ship it can save you time, money, and effort by ensuring that all parts are working properly together before they get shipped out to customers who may be waiting on them. It’s also good practice because it allows you to see how well all of your products are working together before they’re shipped out, which will help prevent issues later on down the line.

“I recently ordered a customized circuit board from PCBTok. They were able to create my design and give me a quote in less than 48 hours. I was impressed that they were so quick and responsive. Most companies would take days to get back to you. The best part is that they showed up at my office the day after I ordered the PCB! They dropped it off at my office with everything I needed and even checked to see if I had questions about assembling the product.”Brad Elery, Mechanical Engineer from Quebec, Canada
“I was in need of a last minute PCB from China. I did not have time to send my design to a local supplier. I found PCBTok on the web and I was able to send my design directly to them. The following day they sent me a quote, and they shipped it after receiving payment. The PCB arrived at my office within a week of ordering. I am impressed with their service, communication and shipping speed!”Blake Johnsons, Electronics Technologist from Kallang, Singapore

Thanks! “Carlos Vives, Process Engineer from Bogota, Colombia
The quality of the BGA PCB is determined by several factors. Some of them are the type of BGA, the quality of BGA placement, and the thickness of the board.
The type of BGA affects your PCB’s quality because each type has its own set of requirements. For example, some BGAs require a foil underlayment to help hold them in place during soldering. Others may need an insulating layer to prevent shorts from occurring when they’re placed on the surface.
The placement quality also affects your BGA PCB’s quality because it can make or break how well your product performs. If an engineer doesn’t have proper training in making sure their BGA placement is accurate, they could end up with a faulty product that doesn’t work properly or even worse, creates dangerous situations for consumers!
The thickness of your board will affect its quality if it’s too thin or too thick compared to what it should be for the electronics inside it; this can cause problems like short circuits or even fire hazards if you don’t get it right!
While BGA rework is a more complicated process than the other types of rework, it is also one of the most common. With a BGA rework, you need to carefully remove the old solder from the pads and replace it with new solder. This can be done using a hot air gun or by using a solder wick tool. You will also need to remove any excess solder from under each pad before applying new solder paste.
After removing the old solder, you should clean the surface of each pad and then apply new solder paste. After that, you can place your components back onto their respective pads and reflow them in an oven. The oven must be set to its lowest temperature setting, which will typically be around 200 degrees Celsius (392 Fahrenheit).
There are a lot of different ways to clean a BGA PCB, but the most important thing you need to know is that you should never use a solvent. Solvents like acetone or alcohol can damage the BGA connectors, which can cause them to break down over time.
Instead, you should use a dry cleaning method. The best way to do this is with compressed air or an air duster. You can also use an ultrasonic cleaner if you have one available.
If you don’t have any of these options available, it’s possible to use a toothbrush in order to clean the circuit board surface without damaging it or leaving behind any residue.
