■ Manufacturing Guidelines
● Storage and Handling
1. Moisture-proofing: These parts are shipped in vacuum-sealed bags to keep them dry and ready for use.

2. Store these parts between 5°C and 30°C, at a relative humidity of less than 70%; for no more than one year
from the production date.
3. After breaking the package seal, maintain the environment within 5°C to 30°C, at a relative humidity of less than
60%. Solder the parts within 3 days.
4. If the parts will not be used immediately, repack them in a dry box, or re-vacuum-seal them with a desiccant.
5. If the parts are exposed to air for more than 3 days, or if the silica gel telltale indicates moisture contamination,
bake the parts:
• When in the tape carrier, bake them at a temperature of 60°C to 65°C, for 36 to 48 hours.
• When loose or on a PCB, bake them at a temperature of 100°C to 120°C, for at least 12 hours.
• Note that the reels may become distorted if they are in a stack when baking. Confirm that the parts have cooled
to room temperature after baking.
● Cleaning Instructions
1. Sharp does not recommend cleaning printed circuit boards containing this device, or cleaning this device with
ultrasonic methods. Process chemicals will affect the structural and optical characteristics of this device.
2. Sharp recommends the use of a solder paste that does not require cleaning.
