Selecting the right BGA rework station that meets your needs can greatly enhance your efficiency. If you are procuring a BGA rework station for a company, your primary consideration should be how to reduce costs. Here, cost does not only refer to the equipment cost but also includes time, labor, and the cost associated with the success rate of rework. Only by considering these three points and selecting a manufacturer accordingly can you find a cost-effective Station de reprise de BGA. So, how do you choose a BGA rework station? Let me explain how to choose a cost-effective BGA rework station in detail.
Choosing the right BGA rework station is crucial. Therefore, first, we need to determine the size of the PCBA board to be reworked. If the BGA rework station can only handle a small area of the PCBA board, it won’t be able to preheat the entire board. This can lead to various issues such as board deformation, bubbles, yellowing, warping, delamination, etc., during subsequent heating. Therefore, when buying a BGA rework station, choose one that can handle a rework range larger than the PCBA board area.
Temperature accuracy is a key consideration when selecting a BGA rework station. During BGA rework, the temperature difference should not exceed 3°C. The smaller the temperature difference, the better. However, this is not absolute and depends on the requirements of different chips during rework. For example, if reworking closely spaced BGA chips, there are specific standards for the temperature difference between adjacent BGAs. The requirement may be that the temperature of the solder balls between adjacent BGAs is below 183°C. Choosing a BGA rework station depends on considering these details.
There are many models and prices of BGA rework stations. So, how do you choose a BGA rework station? Here’s a tip: try to choose one with comprehensive functionality. When comparing between two-zone and three-zone BGA rework stations, never skimp on cost and regret it later. It’s always better to choose a three-zone BGA rework station. Similarly, when comparing between optical alignment and non-optical alignment BGA rework stations, it’s better to choose optical alignment, as it’s difficult to change later if you opt for non-optical alignment. Silman Tech’s optical alignment BGA rework station has a rework success rate of over 95%.
These are all the details about how to choose a BGA rework station and which BGA rework station manufacturer offers the best value for money. In fact, it’s simple logic: choose based on the basic functions you need. Find the manufacturer with the highest success rate for rework; that’s the good manufacturer.
