ø5mm bi-color LED (common anode)

Distributed by Conrad Electronic SE
Precautions:
TAKE NOTE OF THE FOLLOWING IN USE OF LED
1) Temperature in use
Since the light generated inside the LED needs to be emitted to outside efficiently, a resin with
hight light transparency is used; therefore, additives to improve the heat resistance or moisture
resistance (silica gel, etc) which are used for semiconductor products such as transistors
cannot be added to the resin.
Consequently, the heat resistant ability of the resin used for LED is usually low; therefore,
please be careful on the following during use.
Avoid applying external force, stress and excessive vibration to the resins and terminals at
high temperature. The glass transition temperature of epoxy resin used for the LED is
approximately 120-130
℃
.
At a temperature exceeding this limit, the coefficient of liner expansion of the resin doubles or
more compared to that at normal temperature and the resin is softened.
If external force or stress is applied at that time, it may cause a wire rupture.
2) Soldering
Please be careful on the following at soldering.
After soldering, avoided applying external force, stress and excessive vibration until the
products go to cooling process (normal temperature). <Same for producrs with terminal leads>
(1) Solder measurements:
Distance between melted solder side to bottom of resin shall be 1.6mm or longer.
(2) Dip soldering:
Pre-heat: 90
℃
max. (Backside of PDB), within 60 seconds.
Solder bath: 260 ±5
℃
(Solder temperature), within 5 seconds.
(3) Hand soldering: 350
℃
max. (Temperature of soldering iron tip), within 3 seconds.
3) Insertion
Pitch of the LED leads and pitch of mounting holes need to be same.
4) Others
Since the heat resistant ability of the LED resin is low. SMD components are used on the same
PCB. Please mount the LED after adhesive baking process for SMD components. In case
adhesive baking is done after LED lamp insertion due to a production process reason.
Make sure not to apply external force, stress and excessive vibration to the LED and follow the
conditions below.
Baking temperature: 120
℃
max. Baking time: within 60 seconds.
If soldering is done sequentially after the adhesive baking, please perform the soldering after
cooling down the LED to normal temperature.
