Notes
Lead Forming
1. During lead frame bending, the lead frame should be bent at a distance more than 3mm from
bottom of the epoxy.
Note: Must fix lead frame and do not touch epoxy before bending to avoid Photo Interrupter
broken.
2. Lead forming should be done before soldering.
3. Avoid stressing the Photo Interrupter package during leads forming. The stress to the base
may damage the characteristics of Photo Interrupter, or it may break the Photo Interrupter.
4. Cut the Photo Interrupter lead frame at room temperature. Cutting the lead frame at high
temperatures may cause failure of the Photo Interrupter.
5. When mounting the Photo Interrupter onto a PCB, the PCB holes must be aligned exactly with
the lead position of the Photo Interrupter. If the Photo Interrupter are mounted with stress at
the leads, it causes deterioration of the epoxy resin and this will degrade the Photo Interrupter.
Storage
1. The Photo Interrupter should be stored at 10~30°C and 70%RH or less after being shipped
from Everlight and the storage life limits are 3 months. If the Photo Interrupter are stored for 3
months or more, they can be stored at 10°C~25°C and 20%RH~60%RH for a year in a sealed
container with a nitrogen atmosphere. After opening the package, the devices must be stored
at 10°C~25°C and 20%RH~60%RH, and suggested to be used within 24 hours or as soon as
possible. Besides, suggest that the remaining devices seal in the package bag as soon as
possible please.
2. Please avoid rapid transitions in ambient temperature, especially in
high humidity environments where condensation can occur.

Soldering
1. Careful attention should be paid during soldering. When soldering, leave more than 3mm from
solder joint to epoxy bulb, and soldering beyond the base of the tie bar is recommended.
2. Recommended soldering conditions:
Hand Soldering
DIP Soldering
Temp. at tip of iron
300°C Max. (30W Max.)
Preheat temp.
100°C Max. (60 sec Max.)
Soldering time
3 sec Max.
Bath temp. & time
260 Max., 5 sec Max
Distance
3mm Min.(From solder
joint to epoxy bulb)
Distance
3mm Min. (From solder joint
to epoxy bulb)
3. Recommended soldering profile
4. Avoiding applying any stress to the lead frame while the Photo Interrupter are at high
temperature particularly when soldering.
5. Dip and hand soldering should not be done more than one time
6. After soldering the Photo Interrupter, the epoxy bulb should be protected from mechanical
shock or vibration until the Photo Interrupter return to room temperature.
7. A rapid-rate process is not recommended for cooling the Photo Interrupter down from the peak
temperature.
8. Although the recommended soldering conditions are specified in the above table, dip or hand
soldering at the lowest possible temperature is desirable for the Photo Interrupter.
9. Wave soldering parameter must be set and maintain according to recommended temperature
and dwell time in the solder wave.
Cleaning
Do not clean the Photo Interrupter by the ultrasonic.
Heat Management
1. Heat management of Photo Interrupter must be taken into consideration during the design
stage of Photo Interrupter application. The current should be de-rated appropriately by
referring to the de-rating curve found in each product specification.
2. The temperature surrounding the Photo Interrupter in the application should be controlled.

ESD (Electrostatic Discharge)
1. The products are sensitive to static electricity or surge voltage. ESD can damage a die and its
reliability.
2. When handling the products, the following measures against electrostatic discharge are
strongly recommended:
Eliminating the charge
Grounded wrist strap, ESD footwear, clothes and floors
Grounded workstation equipment and tools
ESD table/shelf mat made of conductive materials
3. Proper grounding is required for all devices, equipment, and machinery used in product
assembly. Surge protection should be considered when designing of commercial products.
4. If tools or equipment contain insulating materials such as glass or plastic, the following
measures against electrostatic discharge are strongly recommended:
Dissipating static charge with conductive materials
Preventing charge generation with moisture
Neutralizing the charge with ionizers
