Descriptions: Please note the following instructions after receiving our chips. The BGA chips you buy have high-tech and nano-prices. For a small number of chips, they are removed from the package and exposed to the air. Therefore, they may adhere to a certain humidity, so in order to avoid quality problems, we recommend that you put them in the baking room at least 100-110 ° C (maximum) for 24 hours. When soldering, make sure that the lead-free/lead-free BGA chip has a temperature of 245-260°C (maximum) and the lead/lead BGA chip has a temperature of 180-205°C (maximum). The welding process is complicated. Soldering/replacement of the chip must be performed by a skilled engineer. Due to the fragile BGA chip, complex structure, a large number of balls, any slightly wrong positioning, careless temperature control or incompletely cleaned PCB boards can lead to insufficient soldering or insufficient soldering. The chip will die as a result. BGA chips are easily damaged by improper soldering. Before buying, you should consider 3 points: 1) Have you bought the right chip? 2) Do you have the right equipment? 3) Are you skilled enough to solder the chip? Returns for parts that have been used on the machine are unacceptable.
