Manual Solder Condition
The specimen should be in the as-delivered condition. Set the soldering iron at a temperature of 300 +/- 10
o
C
(at the iron bit). Place the iron and flux-cored solder in parallel with each and every terminal/lead on the back
of the board for a duration which does not exceed 5 seconds without applying any mechanical stress on the
component body.
It can also be applied under 350 +/- 10
o
C at the iron bit within 3 seconds, please treat it carefully under such
condition.
The chip can’t do DIP soldering.

15-2 After Open the Bag
A.
SMT: Should finish the SMT process within 168 hours
B.
Check the humidity check card: The value should < 20% (blue), if the value >= 30% (red), it means
the IC has got moisture.
C. Factory environment control: <= 30
o
C, <= 60% R.H.
