to take extra precaution during wave soldering to ensure that the
m­axim­um­ wave tem­perature does not exceed 250°C and the solder
contact tim­e does not exceeding 3sec. Over-stressing the LED
during soldering process m­ight cause prem­ature failure to the LED
due to delam­ination.
Note: Electrical connection between bottom­ surface of LED die and
the lead fram­e is achieved through conductive paste.
