Dear buyers:
Please pay attention to follwing instruction upon receipt our chips.
The BGA chips you buy from our company are of high technology and as pricise as nanometer.
For small quantity of chips,they are exposed to the air after being taken out from package.so they probably will adhere to some humidity,thus,in order to avoid quality problem,we suggest that you put them inside a baking chamber for at least 24 hours at 100-110°C(Maximum).
When soldering,please make sure that the temperature for lead-free /No Pb BGA chips is 245-260°C(Maximum),Leaded/Pb BGA chips 180-205°C(Maximum).
The soldering process is complicated.Soldering/replacing chips must be operated by engineers who have proficient skills.
As BGA chips are fragile,complicatedly structured,with mumerous balls,any slightly faulty positioning,careless temperature-comtrol,or incomplete cleaning PCB boards will result in insufficient soldering or missing soldering.the chips will ,as a result ,die.
