Dear buyer
After receiving our chip, please pay attention to the following instructions.
The BGA chip you purchased from our company is high-tech and has a precision of up to nanometers.
For a small amount of chips removed from the packaging, they are exposed to air, so they may adhere under certain humidity conditions. Therefore, to avoid quality issues, we recommend storing them in a baking room at 100-110 degrees Celsius for at least 24 hours.
When soldering, ensure that the temperature of lead-free/position free BGA chips is between 245 ° C and 260 ° C (maximum), and the temperature of lead-free/PB BGA chips is between 180 ° C and 205 ° C (maximum).
The welding process is complex, and welding/replacing chips must be operated by qualified engineers.
Due to the fragility, complex structure, and numerous spheres of BGA chips, any minor positioning errors, temperature control negligence, or incomplete PCB cleaning may lead to insufficient soldering or leakage. The chip will die. BGA chips are easily damaged due to improper soldering. Before making a purchase, you should consider three questions:
1. Did you buy the right one?
2. Do you have the appropriate equipment?
3. How much do you know about chip soldering technology?
