2) Hand Soldering conditions

• Not more than 3 seconds at max. 350ºC, under Soldering iron.

3) Caution

• Lead frames are silver plated copper alloy. This substance has a low thermal coefficient

(easily conducts heat)

• The LEDs must not be repositioned after soldering.

• Do not apply any stress to the lead particularly when heat.

Note : In case the soldered products are reused in soldering process, we don’t guarantee the products.
