Related Information

Applied for:

The SMD LED is widely applied for ordinary electronic equipment (such as office equipment,

communication equipment and household applications). Checking with BETLUX's Sales in

advance for information on applications in which exceptional reliability is required, particularly

when the failure or malfunction of the LEDs may directly jeopardize life or health (such as in

aviation, transportation, traffic control equipment, medical and life support systems and safety

devices).

CAUTIONS for SMD LED
1. Application
The SMD LED is widely applied for ordinary electronic equipment (such as office equipment,
communication equipment and household applications). Checking with BETLUX's Sales in
advance for information on applications in which exceptional reliability is required, particularly
when the failure or malfunction of the LEDs may directly jeopardize life or health (such as in
aviation, transportation, traffic control equipment, medical and life support systems and safety
devices).

2. Storage
The storage ambient for the LEDs should not exceed 30℃ temperature or 70% relative humidity.
It is recommended that LEDs out of their original packaging are IR-reflowed within one week.
For extended storage out of their original packaging, it is recommended that the LEDs be stored
in a sealed container with appropriate desiccant, or in a desiccator with nitrogen ambient.
LEDs stored out of their original packaging for more than a week should be baked at about 60 deg C
for at least 24 hours before solder assembly.

3. Cleaning
Use alcohol-based cleaning solvents such as isopropyl alcohol to clean the LED if necessary

Soldering

When soldering, leave a minimum of 2mm clearance from the base of the base of the lens to the soldering point. Dipping the lens into the solder must be avoided.

Do not apply any external stress to the lead frame during soldering while the LED is at high temperature.

Recommended soldering conditions:

IR Reflow Soldering		Soldering Iron
Pre-Heat	150-180°C	Temperature	300°C Max.
Pre-Heat Time	120sec Max.
Peak Temperature	260°C Max.	Soldering Time	3sec Max.(one time only)
Soldering Time	10 sec Max.

Note: Excessive soldering temperature and/or time might result in deformation of the LED lens or failure of the LED

ESD (Electrostatic Discharge)

Static Electricity or power surge will damage the LED.

Suggestions to prevent ESD damage:

n Use a conductive wrist band or anti-electrostatic glove when handling these LEDs

n All devices, equipment, and machinery must be properly grounded

n Work tables, storage racks, etc. should be properly grounded

n Use ion blower to neutralize the static charge which might have built up on surface of the LED's

plastic lens as a result of friction between LEDs during storage and handling

ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current,

low forward voltage, or “no light on” at low currents. To verify for ESD damage, check for “light on”

and Vf of the suspect LEDs at low currents.

The Vf of “good” LEDs should be>2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP

product.

Drive Method

An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs

connected in parallel in an application, it is recommended that a current limiting resistor be

incorporated in the drive circuit, in series with each LED as shown in Circuit A below.
