could you tell me what is the part you used in the video? Like the thermal coupler, the double sided tape and the heat sink with thread? Where I can buy it?
-
could i use:
1. hair dryer
2. solder gun
3. stove and frying pan
to heat the bottom of the pcd board? -
How do i know what side to solder the correct wires to +CutterElectronics

A little more info during the whole process will be helpful for the handy people watching this otherwise very informative video. Specifically all the parts and components used should be introduced and how they function as well.
The paste thing in the beginning, a novice, like myself would certainly not know what that is and would require clarification of that segment as it does seem very important. -
vídeo bem elaborado, parabéns infelizmente não é PT BR.

Hi! Were can i get the cree without the star or circuit board?
-
The temperature is determined by the melt point of the solder you use, around180- 200C is a good start point
-
whats the temperature for soldering?
-
Thanks for watching. The glue is not glue, it is solder paste which reflows with heat to create electrical bond
-
Thanks for this video
Which glue has used to put led on star? -
Thanks for the video. It's very informative& and it helped me greatly. What are the lumens rated at on those particular chips?

Yes there is: don't use a 9-volt battery, they are absolutely horrible for anything over 150-300ma. If you must use a 9-volt, buy a proper switching-mode constant-current driver to bring the voltage down to a reasonable level. You'd be much better off using two lithium-ion cells in series with said driver module; for the same size and weight as a 9-volt, you'll get a lot more performance, and much longer battery life.

No resistor, they used a constant-current LED driver module. Resistors are very inefficient and are not good if the system voltage fluctuates more than 10% or so. A proper driver will work a lot better, produce less heat, and protect your expensive LEDs.

what kind of resistor did you use?
-
Why dont you solder the connecting wires first to the star mount and then attach the led, It will avoid damaging th LED?

Could you power this with a 9 volt? I am thinking these would draw too much amperage? The red one I am looking at is 2.1Vf @ 350 mA or 2.3Vf @ 700 mA, when I look online to step down the voltage with a resistor, the power dissapation across the resistor is very high, around 2.6 watts. I know very little about electronics, is there a better way?

Suggest you show use of flux on the pads you tin. Always say which LED you are using? Why use a 20mm star, not say 16mm? Your iron looked low in wattage, would not a 60 watt iron with slightly bigger tip have been more useful? If reflow technique is used to mount the LED what temp should be sought, what solder, what flux paste & typically how long would this take? What is the blue film you put on & them take off? What is the heat sink & what is its capacity what wattage LEDs can it cope with?

Hello, I would like to make this kind of soldering at home, as the leds I want aren't available pre-mounted in stars.Do you think is as easy as it looks? I will use Osram Oslons thought, that are slightly smaller. What kind of soldering paste do you use? regards.

we use lead and lead free

What kind of solder paste y'all use?

This is a basic demonstration of reflowing a Cree XML Led on a 20mm Star MCPCB and attaching wires and a heatsink and optic to show how you can assemble a complete basic light source from an extremely bright LED.www.cutter.com.au
