3) Similarly, when a jig is used to solder the LED to PC board, take care as much as possible to
avoid steering the leads (See Fig.3).

4) Repositioning after soldering should be avoided as much as possible. If inevitable, be sure to
preserve the soldering conditions with irons stated above: select a best-suited method that
assures the least stress to the LED.
5) Lead cutting after soldering should be performed only after the LED temperature has returned to
normal temperature.
STORAGE
1) The LEDs should be stored at 30℃ or less and 70% RH or less after being shipped from PARA
and the storage life limits are 3 months .
2) PARA LED lead frames are comprised of a stannum plated iron alloy. The silver surface may be
affected by environments which contain corrosive gases and so on. Please avoid conditions
which may cause the LEDs to corrode, tarnish or discolor. This corrosion or discoloration may
cause difficulty during soldering operations. It is recommended that the LEDs be used as soon
as possible.
Please avoid rapid transitions in ambient temperature, especially, in high humidity environments
where condensation can occur.
