RECOMMENDED WAVE SOLDERING PROFILE:
Soldering General Notes:

Through-hole displays are incompatible with reflow soldering.
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:

Mild "no-clean" fluxes are recommended for use in soldering.
If cleaning is required, Kingbright recommends to wash components with water only.
The cleaning process should take place at room temperature and the devices should not be washed for more than one minute.
When water is used in the cleaning process, immediately remove excess moisture from the component with forced-air drying afterwards.

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:

The installation process should not apply stress to the lead terminals.
When inserting for assembly, ensure the terminal pitch matches the substrate board's hole pitch to prevent spreading or pinching the lead terminals.
The component shall be placed at least 5mm from the edge of PCB to avoid damage caused by excessive heat during wave soldering.
CIRCUIT DESIGN NOTES:

Protective current-limiting resistors may be necessary to operate the LEDs within the specified range.
LEDs mounted in parallel should each be placed in series with its own current-limiting resistor.
The driving circuit should be designed to protect the LED against reverse voltages and transient voltage spikes.
The safe operating current should be chosen after considering the maximum ambient temperature of the operating environment.
Prolonged reverse bias should be avoided, as it could cause metal migration, leading to an increase in leakage current or causing a short circuit.
