SOLDERING
• Recommended Hand Soldering Condition
* For a better thermal performance, copper alloy is used for the leadframe of the product.
* Solder the LED no closer than 3mm from the base of the lens.
* Dip soldering/hand soldering must not be performed more than once.
* Care should be taken to avoid cooling at a rapid rate and ensure the peak temperature ramps down slowly.
* When soldering, do not apply stress to the lead frame while the LED is hot.
* After soldering, the LED position must not be corrected.
* After soldering, NO mechanical shock or vibration should be applied to LED lens
* In order to avoid damage on the lens during cutting and clinching the leads,
* When it is necessary to clamp the LEDs to prevent soldering failure,
* Cut the LED lead frames at room temperature. Cutting the lead frames at high temperature may cause failure of the LEDs.
Care must be taken for the soldering conditions and handling of the products after soldering.
Soldering beyond the base of the tie bar is recommended.
until the LEDs cool down to room temperature.
it is not recommended to solder the LEDs directly on customer PCB without any gap between the lens and the board.
If it is unavoidable, customer is advised to check whether such soldering will not cause wire breakage or lens damage.
Direct soldering to double-sided PCBs must be avoided due to an increased effect of heat on the lens.
it is important to minimize the mechanical stress on the LEDs.
