This typically applies to wave soldering processes. For reflow soldering, a standard lead-free profile with a peak temperature not exceeding 260°C should be used, ensuring the time above liquidus is controlled. Prolonged exposure to high temperature can cause internal wire bond failure, epoxy cracking, or degradation of the LED chip's optical properties. It is recommended to avoid mechanical stress on the pins during insertion. The device should be stored in its original moisture-barrier bag until use to prevent moisture absorption, which can cause \"popcorning\" during soldering.
