In this tutorial, we learn how to solder a 0603 LED. First you will get a business card or card with a piece of masking tap. Then, place our LED on the masking tape and apply posts to it. From here, you will apply some solder to the LED as well. Make sure you apply enough pressure to the LED so it will not pop up. Use just small touch of solder and put it on the top of the iron. Touch both sides of the contact and you will have enough solder on the LED. This will finished your soldering, just add wires!
