I have everything done except solder to the #4 LED. This seems very small. Any tips on how to solder to it? I assume I cannot get any on the traces around it?
I would assume the led contact is for a indicator, and not a swap of leds. I personally have never had any problems with this, but alot of people have.
the way I do it is:
strip the wire you want to attach, only a very small amout like 1/8-1/4 inch bare wire. next affix a small blob of solder to the bare end of this wire. now after blob has dried, hold it next to the led. use a small clamp or piece of tape so it dont move now just brush the tip of your iron across the blob. just touch it dont hold your iron there. keep tapping it with your iron untill it bonds. DONOT OVER HEAT!!!!! BONDING SHOULD HAPPEN ALMOST INSTANTLY
the biggest problem people have is over heating the led.
