Precautions For Use
1. Over Current Proof
Resistors must properly applied for protection, slightly voltage shift will cause big current
change, BURN OUT will happen.
2. Storage Time
2.1. The operating temperature and RH: 5
o
C ~ 35
o
C, RH60%.
2.2. Once the package is opened, the products should be used within a week. Otherwise, they
should be kept in a damp proof box with desiccating agent. Taping life considering,
strongly suggest using this products within one year from date of production.
2.3. Package opened more than one week in an normal atmosphere environment, before
soldering, they should be treated at 60
o
C ± 5
o
C for 15 hrs.
2.4. When the desiccant agent changed to pink, the device should be treated as condition 2.3.
Rework Soldering Heat Reliability
1. Rework must be finished within 5 sec.
under 245
o
C.
2. The head of Iron must not touch the
copper foil.
3. Twin-head type is preferred.
Reflow Temp. / Time
Soldering Iron
Basic spec is ≦5 sec. / 260
o
C. If
temperature is higher, time should be
shorted (+10
o
C→-1 sec.). Power
dissipation of Iron should be smaller than
15 W, and temperature should be
controllable. Surface temperature of the
device should be under than 230
o
C.
