█ Description：
：：
：
z The 42-21 SMD Taping is much smaller than
leaded components, thus enable smaller board
size, higher packing density, reduced storage
space and finally smaller equipment to be
obtained.
z Besides, lightweight makes them ideal for
miniature application, etc.

█ Applications：
：：
：
z Automotive: backlighting in dashboard and switch.
z Telecommunication: indicator and backlighting in telephone and fax.
z Flat backlight for LCD, switch and symbol.
z General use.

■ 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 time
2.1 The operation of temperature and R.H. are : 5℃~35℃, R.H.60%.
2.2 Once the package is opened, the products should be used within a week.
Otherwise, they should be keeping in a dampproof box with desiccants.
Considering the tape life , we suggest our customers to use our 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.

■ 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 sm aller than 15 W , 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. Tw in-head type is preferred.
