LAMP HANDLING AND APPLICATION PRECAUTIONS
STORAGE
1. It is recommended to store the products in the following conditions:
a. Humidity: 60% RH Max
Temperature: 5°C ~ 40°C (41°F ~ 105°F)
b. Shelf life in sealed bag: 3 month < 40°C and 90% RH
FORMING
1. Any forming on lead pin must be done before solding, not during or after soldering
2. Avoid applying any stress to resin in order to prevent the epoxy fracture and break on
bonding wire.
3. While forming, please use a tie bar cut or equivalent ot hold or bend the pin.
4. 2mm from the base of resin is the minimum distance for the place bending the lead pin
5. Avoid bending the lead pin at the same point twice or more
SOLDERING
1. No stress can be applied to lead pins when they are heated, otherwise disconnection may
occur.
2. When an LED is mounted into a P.C. board, pitch spacing should be aligned carefully to
avoid causing any stress to the lead wires.
3. Mounting direction (electrode direction) of SMD LED and Display should be
perpendicular to direction of PCB curve
4. After soldering, don’t bend the PCB
CLEANING
1. Avoid using any unspecified chemical solvent to clean LED. For example,
Trichoroethylene, Chlorosen, Acetone, and Diflon S3MC.
2. Any cleaning method can only be taken under normal temperature in one minute or less if
it is required
3. Special attention should be taken when using any chemicals for claning because some
chemicals may damage the surface of epoxy.
