Suggestions to prevent ESD damage: Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs. All devices, equipment, and machinery must be properly grounded. Work tables, storage racks, etc. should be properly grounded. Use ion blower to neutralize the static charge which might have built up on surface of the LED’s plastic for N/D as a result of friction between LEDs during storage and handling. 7/13 Part No. : LTD-4830CTB-P BNS-OD-FC002/A4 LED DISPLAY LTD-4830CTB-P 5.3.

The displays should be stored at 30°C or less and60% RH or less. Once the package opened, moisture absorption begins. If the parts are not stored in dry conditions, they must be baked before reflow to prevent damage to the parts. Baking should only be done once Package In Reel In Bulk Temperature 60°C 100°C 125°C Time ≧48hours ≧4hours ≧2hours 13/13 Part No. : LTD-4830CTB-P BNS-OD-FC002/A4
