The base current Ib should high enough so that it saturates the collector current of the transistor with the CB load.

 

G. Soldering Condition
(1)Recommendable reflow soldering condition is as follows
(Reflow soldering is twice)
Note:It is requested that reflow soldering should be executed after heat of product goes down to normal.
