RECOMMENDED WAVE SOLDERING PROFILE Soldering General Notes

1. Through-hole displays are incompatible with reflow soldering.

2. If components will undergo multiple soldering processes,

or other processes where the components may be subjected

to intense heat, please check with Kingbright for compatibility.

CLEANING

1. Mild "no-clean" fluxes are recommended for use in soldering.

2. If cleaning is required, Kingbright recommends to wash

components with water only. Do not use harsh organic

solvents for cleaning because they may damage the plastic

parts .

3. The cleaning process should take place at room temperature

and the devices should not be washed for more than one

minute.

4. When water is used in the cleaning process, Immediately

remove excess moisture from the component with forced-air

drying afterwards.

Notes:

1. Recommend pre-heat temperature of 105°C or less (as measured with a thermocouple

attached to the LED pins) prior to immersion in the solder wave with a maximum solder bath

temperature of 260°C

2. Peak wave soldering temperature between 245°C ~ 255°Cfor 3 sec (5 sec max).

3. Do not apply stress to the epoxy resin while the temperature is above 85°C.

4. Fixtures should not incur stress on the component when mounting and during soldering process.

5. SAC 305 solder alloy is recommended.

6. No more than one wave soldering pass.

7. During wave soldering, the PCB top-surface temperature should be kept below 105°C.

PACKING & LABEL SPECIFICATIONS

THROUGH HOLE DISPLAY MOUNTING METHOD

Lead Forming

Do not bend the component leads by hand without

proper tools. The leads should be bent by clinching the

upper part of the lead firmly such that the bending force

is not exerted on the plastic body.

Installation

1. The installation process should not apply stress to the lead terminals.

2. When inserting for assembly, ensure the terminal pitch matches the substrate board's hole pitch to prevent spreading or pinching

the lead terminals. (Fig.1)

3. The component shall be placed at least 5mm from edge of PCB to avoid damage caused excessive heat during

wave soldering.(Fig.2)

CIRCUIT DESIGN NOTES

1. Protective current-limiting resistors may be necessary to operate the LEDs within the specified range.

2. LEDs mounted in parallel should each be placed in series with its own current-limiting resistor.(Fig.3)

3. The driving circuit should be designed to protect the LED against reverse

voltages and transient voltage spikes when the circuit is powered up

or shut down.

4. The safe operating current should be chosen after considering the

maximum ambient temperature of the operating environment.

5. Prolonged reverse bias should be avoided, as it could cause metal

migration, leading to an increase in leakage current or causing

a short circuit.
