ALMD-CY3F-YZ002

Data Sheet ALMD-CY3F-YZ002 High Brightness SMT Round White LED Lamps Overview The new Broadcom® ALMD-CY3F series is essentially like a conventional high brightness through-hole LED in the form of a surface mount device. It can be assembled using common SMT assembly processes and is compatible with industrial soldering processes. The LEDs are made with an advanced optical grade epoxy for superior performance in outdoor sign applications. For 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      High brightness InGaN Typical viewing angle: 30° Supports EN12966-1 white color class C2 JEDEC MSL3 Compatible with industrial reflow soldering process Applications   Variable message signs Highway signs CAUTION! This LED is ESD sensitive. Please observe appropriate precautions during handling and processing. Refer to application note AN-1142 for additional details. The LED must be kept in a moisture barrier bag with < 5% relative humidity (RH) when not in use because prolonged exposure to the environment might cause the leads to tarnish or rust, which might cause difficulties in soldering.

ALMD-CY3F-DS100 8 ALMD-CY3F-YZ002 Data Sheet High Brightness SMT Round White LED Lamps Precautionary Notes Handling Precautions Soldering      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 Do not touch the LED package body with the soldering iron except for the soldering terminals, because it may cause damage to the LED. Confirm beforehand whether the functionality and performance of the LED is affected by soldering with hand soldering. For automated pick-and-place, Broadcom has tested the following nozzle size to work well with this LED. However, due to the possibility of variations in other parameters, such as pick-and-place machine maker/model, and other settings of the machine, verify that the selected nozzle will not cause damage to the LED.

Broadcom ALMD-CY3F-DS100 9 ALMD-CY3F-YZ002 Data Sheet Handling of Moisture-Sensitive Devices High Brightness SMT Round White LED Lamps  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 unused LEDs in a sealed MBB with desiccant or in a desiccator at < 5% RH. This product has a Moisture Sensitive Level 3 rating per JEDEC J-STD-020. Refer to Broadcom Application Note AN5305, Handling of Moisture Sensitive Surface Mount Devices for additional details and a review of proper handling procedures.    Before use: – An unopened moisture barrier bag (MBB) can be stored 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, it is safe to reflow the LEDs per the original MSL rating. – Do not open the MBB prior to assembly (for example, for IQC). If unavoidable, the MBB must be properly resealed with fresh desiccant and HIC. The exposed duration must be taken in as floor life. Control after opening the MBB: – Read the HIC immediately upon opening of 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: Application Precautions     Store unused LEDs in a sealed MBB with desiccant or a 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 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 168 hours. The recommended baking condition is: 60°C ± 5ºC for 20 hours. Baking can only be done once. Broadcom Storage:     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. Circuit design must cater to the whole range of forward voltage (VF) of the LEDs to ensure the intended drive current can always be achieved. The LED exhibits slightly different characteristics at different drive currents, which may result in a larger variation of performance (meaning: 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, ensure that the reverse bias voltage does not exceed the allowable limit of the LED. White LEDs must not be exposed to acidic environments and must not be used in the vicinity of any compound that may have acidic outgas, such as, but not limited to, acrylate adhesive. These environments have an adverse effect on LED performance. As actual application might not be exactly similar to the test conditions, do verify that the LED will not be damaged by prolonged exposure in the intended environment. Avoid rapid changes in ambient temperature, especially in high-humidity environments, because they cause condensation on the LED. If the LED is intended to be used in harsh or outdoor environments, protect the LED against damages caused by rain water, water, dust, oil, corrosive gases, external mechanical stresses, and so on.
