Data Sheet Overview The Broadcom® ASMB-UTF0 is a series of tricolor LEDs in PLCC-6 package. The package is (2.8 x 2.8) mm, and it is designed for small pitch display. The black outer appearance helps to improve the contrast of the display. To facilitate easy pick-and-place assembly, the LEDs are packed in a tape and reel format. Every reel is shipped in single intensity and color bin to ensure uniformity. Features ■ PLCC-6 package with black outer appearance ■ Short leads for better potting process ■ Diffused encapsulation ■ Compatible with reflow soldering process ■ MSL 5a Applications ■ Outdoor full color display CAUTION! This LED is ESD sensitive. Observe appropriate precautions during handling and processing. Refer to application note AN-1142 for additional details.

Precautionary Notes Handling Precautions Do not perform reflow soldering more than twice. Observe necessary precautions of handling moisturesensitive devices as stated in the following section. Do not apply any pressure or force on the LED during reflow and after reflow when the LED is still hot. Use reflow soldering to solder the LED. Use hand soldering only for rework if unavoidable, but it must be strictly controlled to following conditions: – Soldering iron tip temperature = 315°C maximum – Soldering duration = 3s maximum – Number of cycles = 1 only – Power of soldering iron = 50W maximum...

ASMB-UTF0-0D20B Data Sheet 2828 Tricolor PLCC-6 LED ■ Baking is required if: - The HIC indicator indicates a change in color for 10% and 5%, as stated on the HIC. - The LEDs are exposed to conditions of >30°C/60% RH at any time. - The LED's floor life exceeded 24 hours. The recommended baking condition is: 65°C ± 5°C for 24 hours. Baking can only be done once. ■ Storage: The soldering terminals of these Broadcom LEDs are silver plated. If the LEDs are exposed in ambient environments for too long, the silver plating might be oxidized, thus affecting its solderability performance. As such, keep...

Eye Safety Precautions LEDs may pose optical hazards when in operation. Do not look directly at operating LEDs because it might be harmful to the eyes. For safety reasons, use appropriate shielding or personal protective equipment.
