  • is it possible to solder the emiter onto the star in an oven? or would this damage the emitter?

  • @monkey08642

    It would be possible.

    But, as I found out recently, heating the whole part from underneath with a hot air gun works better and faster.

  • Well, a split second touch does not transfer enough heat into the skin to cause severe burns. It's like moving the finger quickly through a candle flame; we all did this as kids :-)

    But recently, I found out that it is much simpler to put the basis in a third hand, and to heat the thing from below with a hot air gun. Then remove the Cree with tweezers. Place it on the other base, heat it from below, too, done. Much simpler.

  • If I wanted to solder the LED to the board, could I heat the back of the board with a soldering iron or would that not work?

  • Keep in mind that LED structure is a crystal. By cooling it in a water, You 're shortening its life around ten times. On Cree homepage is preety big tutorial about soldering them. I make LED lighting for living. Trust me. Things like that only kill diodes. It's 100 times better to let it cool on its own.

  • Excellent, very nice video, interesting, Thanks

    You can also see my video, cree led and with solar

    Congratulations and Good Continuation

  • WOW.. you touched the heatsink star?  I had to use a rock to separate mine it was so hot.
