With the increasing prevalence of products using BGA packaging, such as laptops, smartphones, network cameras, TV motherboards, and more, the application of BGA chips in China is strongly supported and encouraged. However, the level of BGA repair technology is significant, so it’s crucial to choose the right BGA rework station. Here, Silman Tech will explain some key points to consider when purchasing a BGA rework station.
Basic Considerations:
- Select Based on the PCB Size of the Products You Need to Repair: Most customers buying BGA rework stations use them to repair BGA chips on laptops or desktop computers. It’s essential to understand the maximum repair size of the BGA rework station you’re considering.
- Consider Chip Size: Most manufacturers provide corresponding nozzle sizes, and custom nozzle sizes can also be ordered. Silman Tech’s nozzles are standard, but custom sizes are available upon request. Therefore, you don’t need to worry about not having the right nozzle size for your chip.
Functional Considerations:
Most rework stations on the market now have three temperature zones, which is a crucial feature. Three temperature zones refer to the heating zones in the upper, lower, and bottom parts of the machine. Currently, most rework stations in China use hot air for the upper and lower parts and infrared preheating for the bottom. This is the current trend. Rework stations with only two temperature zones usually omit infrared preheating or bottom hot air. I strongly advise against purchasing such models because saving a little money is not worth compromising the quality of rework.
Other factors to consider include whether the rework station comes with a vacuum pen (to remove the BGA after rework), cross-flow cooling fans (for rapid cooling to prevent PCB deformation), and delayed heating functions (to extend heating time when the set temperature is insufficient). However, these are basic features that most BGA rework stations should have to facilitate user convenience.
Finally, after-sales service and brand reputation are crucial factors to consider. These aspects provide assurance and support in case of any issues. It’s not advisable to blindly opt for the cheapest option if there is no after-sales service available. It’s not worth it if there’s no one to turn to when problems arise.
