Some Skills About Using a BGA Rework Station System
The development of electronic components has become increasingly important as they become smaller and more complex, with more pins (legs). This trend has led to the development of more complex and expensive systems, such as BGA (Ball Grid Array) and CSP (Chip-on-Board) versions, making it difficult to verify the reliability of welds that may be compromised by configuration issues in the cavity. The quality of manual soldering depends on various factors, including the operator's skill, the quality of the materials used, and the effectiveness of the rework station.
Manual soldering is also influenced by the evolving technological landscape, which constantly demands innovative solutions. In manual soldering, the performance of the welding or rework station is closely tied to the operator's skill. A well-designed rework station can achieve excellent results even with a less experienced operator. Conversely, even the most skilled operator cannot overcome the limitations of a poor welding system.
This process has been established to improve rework efficiency, as recovery during rework is often more cost-effective than replacement. High-tech equipment used in rework stations provides excellent control over key variables, ensuring consistent results. This technology allows for efficient heat transfer, which enables repeated soldering at a constant temperature, minimizing vibration caused by slow heat recovery.
The rework process can be broken down into four main stages:
- Removal of components
- Cleaning of pads
- Placement of new components
- Soldering
One of the significant challenges at the production level is applying solder paste to pads when modifying components. If this step is not done correctly, it can negatively affect the integration process in the subsequent stages. If your budget allows, a vision system is highly recommended to improve accuracy.
Additional practical difficulties arise during the rework process, especially as the number of terminals increases and their pitch (spacing) decreases. Typically, the size of the circuit board also shrinks, which reduces the available space and increases the risk of interference with surrounding components.
