Choosing the right brand of BGA rework station may pose a challenge for those who are new to Equipamento de retrabalho BGA. To select a high-quality and practical BGA rework device, it is essential to understand several factors, such as whether a three-zone or two-zone system is preferable, the size of the PCBA boards you need to rework, and other considerations. Here’s a guide on how to choose the right brand of BGA rework station:
- Before selecting a brand of BGA rework station, it is crucial to determine the size of the Chips BGA you need to rework. The size of the chips will determine the appropriate size of the nozzle to choose. It’s preferable to select a machine with a larger size compatible with BGA chips, as it allows for better preheating of the PCB boards. If the rework area is too small, the PCB board may be prone to deformation, blistering, discoloration, or delamination. Therefore, opting for a brand of BGA rework station with a larger rework area ensures a broader range of rework capabilities.
- Choose a brand of BGA rework station with minimal temperature difference between zones. A lower temperature difference indicates a higher success rate for rework. Temperature precision is crucial for BGA rework stations, with an industry standard of within ±3 degrees Celsius. Currently, there are two-zone and three-zone systems available, with the main difference being the heating zone at the bottom. For lead-free products requiring higher temperatures, a narrower heating window may be used. Therefore, it is recommended to purchase a three-zone BGA rework station for better performance.
- Determine your rework requirements and budget constraints before selecting a brand. Choose a brand based on its functionality, and consider factors such as pre-sales, in-sales, and after-sales services. Opt for a machine with high rework success rates and ease of operation. For example, Silman Tech’s fully automatic BGA rework station can automatically complete the steps of chip removal and placement without human intervention, ensuring a high yield rate. It can easily rework various devices such as BGA, CSP, POP, WLCP, QFN, Chip0201, 01005, shielding frames (covers), modules, etc.
- Quality should be a primary consideration when choosing a brand of BGA rework station. Assess factors such as build quality, temperature precision meeting industry standards, temperature control, and overall craftsmanship. Only by comparing these criteria can you determine which brand is superior.
- A good brand of BGA rework station should feature PLC-controlled temperature stability and high precision. An integrated design of the upper heating device and placement head can automatically recognize the material suction and placement height, with automatic soldering and desoldering functions. Evaluation of optical alignment systems and the components used is also necessary.
If your rework volume is not particularly high, using a hot air gun may suffice, given its lower price. However, if you intend to purchase a branded BGA rework station, it’s advisable not to compromise on quality. Equipment design, lifespan, and after-sales service are all more reliable with reputable brands.
