A、LED
LAMP Precautions In Use |
1、Soldering Conditions：（Location
At least 2 mm away from resin body）
◆Solder dipping: 260 ℃max., 5
seconds max., one time.
◆Soldering iron: 350 ℃ max., 5
seconds max., one time.
In soldering, do not put any stress on
the lead frame, particularly when
heated. Please avoid conditions which
may cause the LED to corrode.This
corrosion may cause difficulty during
soldering operations.
2、Lead frame
Forming and Use：
◆Lead forming should be performed
prior to soldering.When mounting the
LEDs onto a printed circuit board ,the
holes on the circuit board should be
exactly aligned with the leads of the
LEDs.
◆Cutting the lead frame at high
temperature may cause problems.Cut the
lead frame at room temperature.
◆Care should be taken to avoid any
shock or vibration to the LED resin body
after it has been soldered until the
temperature of he LED has returned to
normal.
3、Static
Electricity
The high brightness Blue、green、white
products are sensitive to static
electricity charge. The customer is
requested to take adequate
countermeasures against static
electricity charge and surge when
handling Products.A tip of soldering
iron is requested to be grounded.
4、Cleaning
Special care shall be taken when
applying the chemicals listed below for
cleaning because certain chemicals such
as Trichloroethylene and Acetone may
damage the surface of lens or case and
cause discoloration., but you can use
Ethyl alcohol cleanse instead，Dipping
time 3 minutes max.at normal
temperature. |

B、CHIP
LED Precautions In Use |
1、Soldering Conditions：
◆ Reflow solder: 240℃ max, 5 seconds
max,one time. Pre-heat is 150℃ max, 2
minutes max.
◆Soldering iron: Power dissipation
of Iron should be smaller than 25W,and
temperature should be controllable.The
work must be finished within 3sec under
320℃, only once.
Do not stress its resin while soldering.
After soldering,do not warp the circuit
board.
2、Package and
Storage：
◆When moisture is absorbed into the
package it may vaporize and expand
during soldering. There is a possibility
that this can cause exfoliation of the
contacts and damage to the optical
characteristics of the LEDs. So the
moisture proof package is used to keep
moisture to a minimum in the package.
◆Before opening the package: The
LEDs should be kept at 5~30℃ and 60%RH
or less. The LEDs should be used within
a year.
◆After opening the package: The LED
must be used within 24 hours, else
should be kept at 5~30℃ and 30% RH or
less. The LEDs should be used within
7days after opening the package. If
unused LEDs remain, they should be
stored in moisture proof packages,
recommended to return the LEDs to the
original moisture proof bag and to
reseal the moisture proof bag again.
◆If the LEDs have exceeded the
storage time, baking treatment should be
performed more than 12 hours at 60℃
◆The LED electrode sections are
comprised of a gold plated. Please avoid
conditions which may cause the LED to
corrode or discolor. It may cause
difficulty during soldering
operations.Please use the LEDs as soon
as possible.
◆Please avoid rapid transitions in
ambient temperature, especially in high
humidity environments.
3、Static

electricity charge. The customer is
requested to take adequate
countermeasures against static
electricity charge and surge when
handling Products.A tip of soldering
