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.
