BGA rework station is a type of equipment that effectively improves assembly yield and significantly increases usage frequency. It can perform assembly-compatible co-planar soldering, exhibiting high reliability, and is favored by many customers. Below is a classification introduction of BGA rework stations, hoping to be helpful to everyone.
- Manual Model
The manual model is suitable for BGA chips with larger ball pitches (0.6 and above). During placement, operators place the BGA on the solder paste printed on the PCB based on experience. Except for the automatic completion of the temperature curve during heating, all other operations require manual operation. Although the manual model operation is relatively cumbersome, it is a more common choice for repairing BGA chips with larger ball pitches.
- Semi-automatic Model
The semi-automatic model is suitable for BGA chips with smaller ball pitches (0.15-0.6mm). Due to the risk of manual placement leading to poor soldering, the semi-automatic model uses optical alignment principles. It enlarges the images of BGA solder joints and PCB pads through a prism imaging system, aligns them vertically after overlapping the enlarged images, thus avoiding placement errors. After placement, the heating system will run automatically and emit a beep alarm as a reminder.
- Fully Automatic Model
The fully automatic model is a high-tech device that achieves automatic repair processes using machine vision technology. It can locate BGA chips and perform automatic repair processes based on machine vision. Although the fully automatic model is relatively expensive, its efficient automation makes it very practical in situations requiring a large number of BGA chip repairs.
In addition to the common classifications mentioned above, there are also special models such as rework stations with 50x magnification positioning, which can be chosen according to actual needs.
The above is an introduction to the classification of BGA rework stations, each model has its characteristics and applicable scenarios. Hopefully, this information can help everyone better choose the BGA rework station that suits their needs. If you are interested in any of the models mentioned, feel free to share your thoughts in the comments section.
