How To Rework Your BGA

1. How To Rework Your BGA

2. If you want to learn how to solder BGAs, you may need the assistance of a BGA reballing service. While many individuals have access to a hot air gun, you can learn how to modify various BGA components in our guide utilizing a variety of standard equipment. Precautions must be taken since high temperatures might be induced even during ordinary operations. For example, high temperatures can cause issues with the tin solder used to attach the pins to pads on the board. Excessive heat may cause the circuit board or the component to shrink or expand over time. With BGA Reballing, you may reuse components instead of throwing them away. The BGA package is separated and rejoined in this operation, saving both money and resources. Redesigning BGA packages decreases the cost from more than 25 percent less than QFP with leads. Moreover, it is essential to note that BGA components have a particular cooling curve, which necessitates expensive equipment for expert repairs. Reworking Your BGA Requires the Following Supplies: You’ll need a soda can, some flux, a hot air gun, tin solder, a vice or a set of pliers, a pair of scissors, and some scrap iron strips.

3. These may be found in pallets, which are used to keep products secure. Step 1 You’ll need to measure your BGA chip correctly. To make a square out of the strip, you’ll need to bend it with a hammer and vice. The strip may also be bent using a pair of pliers, or you can utilize the pliers, hammer, and vice to accomplish the task faster. As a general rule, the square you build should be somewhat more significant than the actual BGA chip you own so that the heat may pass beneath the chip body. Step 2 You’ll need to create a clip for your bracelet using some iron wire. Once you’ve constructed your clip, be sure to save it since you’ll need it to keep everything together later. Step 3 Use scissors or a cutter to open your soda can once you’ve finished drinking it. The next step is to straighten the can and carve out a square hole.

4. Since you made a square frame at the beginning of the process, the hole must have a square form to accommodate it. Aluminum foil from your soda can should be sufficient to insulate the rest of your circuit board components from excessive heat after your hot air cannon has begun heating the chip. If you followed the instructions carefully, you shouldn’t have any problems with your heating system. Step 4 Your soldering flux will need to enter the real BGA chip at this stage. With the use of a little brush, make sure to cover all the areas. Step 5 The next step is to roll a little bit of tin solder into a ball. Next, place your ball somewhere safe since you’ll need it again when the heat is applied. Step 6 Clamping the circuit board to your workbench will ensure that it doesn’t slide around as you work. You can simply heat the chip from beneath if you keep the chip off the surface.

5. Next, you’ll need to take your square frame and aluminum foil and place them in the wire clip that you constructed at the beginning of your project. It’s time to place your tin ball into the BGA chip’s nucleus. The board must be positioned such that the tin solder ball does not roll away after the tin has been heated to a suitable degree. Step 7 Heating is now the most satisfying aspect of the process. Using hot air cannon, begin the heating process by turning it on at a low setting first. Once the tin blob begins to melt, you will need to heat the board both from the bottom and from the top. Afterward, keep the area heated for at least another thirty seconds to ensure that it has completely melted. A shining metallic ball will be formed when it has been heated to the melting point and will roll away from you if you don’t follow our instructions in this guide. As an extra suggestion, make sure that the distance between the chip and your hot air pistol is enough by holding the gun perpendicular to the board and above the chip. You should be able to keep the tin ball in place on your chip if you complete it correctly.

6. Step 8 The final step is to allow the board to cool down. The board should be thoroughly rebuilt when it has cooled down to room temperature. In this way, it will be reused instead of ending up in the trash and being hauled to a local landfill for further disposal. Despite variations in printed circuit boards and BGA devices, the BGA rework process may be carried out systematically by following the steps mentioned above.
