9. Soldering Profile
1) Wave Soldering Conditions / Profile
• Preliminary heating to be at 85ºC(120 ºC max) for 20 seconds(60 seconds max).
• Soldering heat to be at 255 ºC (260ºC max) for 10 seconds
• Soak time above 200 ºC is 5 seconds

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.
