APPLICATION NOTES

Introduction

Kingbright AA3528AVU series are surface-mounted right-angle light-emitting diode (LED) circuit-board indicators. It offers the

convenience of surface-mount production while offering the right-angle height profile of circuit-board indicator lamps. The part is

suitable for automated SMT and lead-free reflow soldering production. The clear silicone lens extends out to provide broad viewing

angles. When installed on customer’s circuit board, it can provide illuminated indication or backlight panel indicators.

Transport and Storage

Surface mount devices (SMD) are moisture sensitive components. Atmospheric moisture will seep into the component package,

so when placed on the circuit board for 160-200°C reflow soldering, the high temperatures cause the absorbed moisture to vaporize

and rapidly expand, creating vapor pressure that could damage the LED component by causing cracks in the lens, delamination

of the chip and wire bonds, or other reliability issues.

1.Transportation

The product is packed in anti-static, moisture-proof mylar bags. The package should be carefully handled to avoid external pressure

and accidental puncture during transport. Proper anti-static practices should be in place. If package leakage or damage is found

before opening, suggest customer take the damaged package off-line for additional testing and bake to dry before use.

2.Storage Conditions (Before Opening)

To prevent moisture-absorption reliability issues, the parts must be properly stored. Suggest do not open the moisture-proof package

until immediately before usage (except for sample inspection purposes). The opened package must be re-sealed with fresh desiccant

and humidity indicator and Stored in a dry box (<30°C/60%RH).

3.Humidity Control (After Opening)

After opening the moisture-proof packaging, immediately check the humidity indicator card contained inside to confirm the parts have

been exposed to excess moisture. The production environment should follow IPC/JEDEC J-STD-020 standards for temperature,

humidity, and exposure time. SMD environmental exposure time accumulates as long as the parts are outside the packaging, unless

they are being baked dry.

PRECAUTIONARY NOTES

1. The information included in this document reflects representative usage scenarios and is intended for technical reference only.

2. The part number, type, and specifications mentioned in this document are subject to future change and improvement without notice. Before production usage customer should refer to

the latest datasheet for the updated specifications.

3. When using the products referenced in this document, please make sure the product is being operated within the environmental and electrical limits specified in the datasheet. If

customer usage exceeds the specified limits, Kingbright will not be responsible for any subsequent issues.

4. The information in this document applies to typical usage in consumer electronics applications. If customer's application has special reliability requirements or have life-threatening

liabilities, such as automotive or medical usage, please consult with Kingbright representative for further assistance.

5. The contents and information of this document may not be reproduced or re-transmitted without permission by Kingbright.

6. All design applications should refer to Kingbright application notes available at http://www.KingbrightUSA.com/ApplicationNotes

4. Storage of Unused and Remaining Parts

If the full reel was not consumed during production, the production environment was within limits (<30°C/60%RH), and the exposure

time did not exceed the limits in Table 1, then the remaining parts may be stored as below:

zRe-sealed with desiccant.

zStored within a dry box (5% RH). The dry box storage time would not count against the total exposure time. When the

stored parts are taken out, the exposure time is accu-mulated from the previous production run.

5. Humidity Control of PCB-Mounted Parts

If the moisture-sensitive SMD parts will not undergo further reflow or other high-temperature processes, then no special treatment is

required. However, if the PCB assembly requires further reflow or other high-temperature process, including rework, then the mounted

SMD’s exposure time should continue to accumulate against the MSL limit, unless the board is kept in a dry environ ment (<5% RH).

If the exposure time exceeds the MSL limit, the board and part must be baked dry to reset the exposure time before undergoing further

reflow.

Installation and Usage

If the part’s silicone lens extends beyond the board’s edge after installation, proper protection Should be made (such as covers) to

prevent accidental impact or stress on the exposed lens that would cause damage or detachment. The silicone lens may withstand

up to 1.5-newton in shear force when properly mounted. If external protection is not available, strongly suggest following these handling

procedures to prevent damage:

1. When the PCB assembly is handled or transported after reflow soldering, care must be taken to

prevent accidental contact or impact on the exposed silicone lens.

2. When the PCB assembly is installed into the casing or panel, care must be taken to maintain

sufficient clearance for the lens.

3. Do not subject the silicone lens to outside impact or friction.

Cleaning

1. Do not use unknown chemicals or acidic solvents to clean the part. Please check to insure the cleaning solvent will notcorode

epoxy resin, silicone resin, silver plating, and other component materials before using.

2. Kingbright suggests ethanol as a safe solvent for use with the surface mount devices. Softly wipe away any surface parcles,

avoiding excessive force scratching the surface or damaging the structures. Then place down and allow to naturally dry under

room temperature conditions before further use. Do not soak the component in the solvent.
