Applications
CAUTION! The LEDs are ESD sensitive per ANSI/ESDA/JEDEC JS-001. Please observe appropriate precautions during handling and processing. Refer to Application Note AN-1142 for additional details. CAUTION! Customers should always keep the LED in the moisture barrier bag (MBB) with < 5% RH when not in use because prolonged exposure to the environment might cause the silver-plated leads to tarnish or rust, which might cause difficulties in soldering.

ALMD-EG1E/2E, ALMD-EL1E/2E Data Sheet High Brightness SMT Round Red, Amber LED Lamps Broadcom ALMD-ExxE-DS102 Precautionary Notes Handling Precautions For automated pick-and-place, Broadcom has tested the following nozzle size made with a urethane material to work well with this LED. However, due to the possibility of variations in other parameters, such as pick-and-place machine, maker and model, and other settings of the machine, verify the selected nozzle before using it. Figure 19: Nozzle Size Handling of Moisture Sensitive Devices This product has a Moisture Sensitive Level 3 rating per JEDEC J-STD-020. Refer to Application Note AN-5305, Handling of Moisture Sensitive Surface Mount Devices, for additional details and a review of proper handling procedures. Before use: You can store an unopened moisture barrier bag (MBB) at <40°C/90% RH for 12 months. If the actual shelf life has exceeded 12 months and the humidity indicator card (HIC) indicates that baking is not required, then it is safe to reflow the LEDs per the original MSL rating. Do not open the MBB prior to assembly (for example, for IQC). Control after opening the MBB: Read the HIC immediately upon opening the MBB. Keep the LEDs at <30°C/60% RH at all times, and complete all high temperature-related processes, including soldering, curing, or rework, within 168 hours. Control for unfinished reel: Store unused LEDs in a sealed MBB with desiccant or desiccator at <5% RH. Control of assembled boards: If the PCB soldered with the LEDs is to be subjected to other high-temperature processes, store the PCB in a sealed MBB with desiccant or desiccator at <5% RH to ensure that all LEDs have not exceeded their floor life of 168 hours. Baking is required if the following conditions exist: The HIC indicator is not BROWN at 10% and is AZURE at 5%. The LEDs are exposed to conditions of >30°C/60% RH at any time. The LED floor life exceeded 168 hours. The recommended baking condition is: 60°C ± 5ºC for 20 hours. Baking should 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 oxidize; thus affecting their solderability performance. As such, keep unused LEDs in a sealed MBB with desiccant or in desiccator at <5% RH. Application Precautions The drive current of the LED must not exceed the maximum allowable limit across temperature as stated in the data sheet. Constant current driving is recommended to ensure consistent performance. LEDs exhibit slightly different characteristics at different drive currents, which might result in larger performance variations (that is, intensity, wavelength, and forward voltage). Set the application current as close as possible to the test current to minimize these variations. The LED is not intended for reverse bias. Use other appropriate components for such purposes. When driving the LED in matrix form, it is critical to ensure that the reverse bias voltage does not exceed the allowable limit of the LED. Avoid rapid changes in ambient temperatures, especially in high-humidity environments, because this situation causes condensation on the LED.
ALMD-EG1E/2E, ALMD-EL1E/2E Data Sheet High Brightness SMT Round Red, Amber LED Lamps Broadcom ALMD-ExxE-DS102 If the LED is intended to be used in outdoor or harsh environments, protect the LED leads with a suitable potting material against damages caused by rain water, oil, corrosive gases and so on. Use a louver or a shade to reduce direct sunlight on the LEDs. The number of reflow cycles and reflow temperature conditions used might affect the optical characteristics of the LED. Use LEDs with the same number of reflow cycles and same reflow temperature conditions within the same finished product. Eye Safety Precautions LEDs might pose optical hazards when in operation. Do not look directly at an operating LED as it might be harmful to the eyes. For safety reasons, use appropriate shielding or personal protective equipments.
