Soldering heat reliability(DIP)
Please refer to the following figure
Soldering Iron
Basic spec is ≦5 sec when 260℃. If temperature is higher , time should be shorter
(+10℃ -1sec ).Power dissipation of Iron should be smaller than 15W ,and
temperature should be controllable. Surface temperature of the device should be
under 230℃.
Rework
1.Customer must finish rework within 5 sec under 260℃
2.The head of iron can not touch copper foil.
3.Twin-head type is preferred.

Reflow Temp./Time
Precautions For Use
1.Over-current-proof
Customer must apply resistors for protection , otherwise slight voltage shift will cause
big current change(Burn out will happen).
2.Storage
2.1 The operation of temperature and R.H are：5℃ ~ 35℃ ， R.H.60%.
2.2 Once the package is opened , the products be should be used within a week.
Otherwise , they should be keep in a damp proof box with desiccation anent.
Considering the tape life , we suggest our customers to use products within a year
(from production date).
2-3.If opened more than one week in an atmosphere 5℃ ~35℃，R.H.60%.,they
should be treated at 60℃± 5℃ for 15hrs.
2-4.When you discover that the desiccant in the package has a pink color(normal=blue),
you should treat them in the same conditions as 2.3
