Step 5: Solder the LEDs

Picture of Solder the LEDs
Here please refer to the step 12 of the original Instructable.

Take time doing this step. LED pins are very close together, so you might have to use solder wick often to clear the solder bridges. Also, use of high-quality flux is essential here. Use pen tip or small brush to apply flux to the pads and leads.

I soldered all of the LEDs without using flux. I would say that if you have a decent soldering iron with a fine tip and a high quality solder with a flux core, flux is not absolutely necessary, although you will probably do a cleaner job if you use it.

You must be very good with your soldering iron!
